Advertorials New 70mm Ø x 20mm centrifugal fan delivers up to


39.9CFM airflow and 560Pa static pressure EAO Ltd has introduced the new Sanyo Denki 9TD12P6G001 70mm Ø x 20mm centrifugal fan with for use in electronic equipment and ventilation systems.


Developed by Sanyo Denki, the San Ace 9TD compact centrifugal fan measures just 70mm Ø by 20 mm but delivers the high static pressure and the airflow demanded by thin high-density equipment with restricted space such as graphics cards, digital signage and for ventilation systems. With its extremely compact size and centrifugal airflow direction it can provide high static pressure and airflow in a smaller depth than an axial fan or typical 76mm blower fan.


When compared to the existing 76 x 20mm Sanyo Denki blowers the new fan provides 1.9 times higher static pressure and 3.9 times higher airflow.


The new San Ace 9TD12P6G001 centrifugal fan is available in 12VDC with a matching inlet nozzle type 109-1106 and features PWM control, which facilitates external control of fan speed for lower noise and high efficiency. Engineered with dual ball bearings the new fan provides reliability figures of 70,000 hours MTBF at 40ºC (40,000 hour at 60ºC), ensuring trouble-free long-term operation.


The 9TD blower fan is part of range of Sanyo Denki, San Ace brand centrifugal fans that also includes 100, 133, 150, 175, 221, 225 and 270mm diameter fans.

New Micro Series waterproof connectors


Selwyn Electronics, the interconnection specialists, have added another series to their extensive range of Waterproof Connectors. These connectors offer an easy push together mate and un- mate friction lock, with up to 6 contacts. With body diameters of less than 10mm, they offer a low cost, robust and reliable connection for a wide variety of applications where small size and water sealing (IP66) is required.


The Micro A series is a 2 way panel mount male with a moulded female plug and is rated at 2A.


The Micro B series is available with a panel mount receptacle, cable mount plug, and cable mount in-line receptacle for cable to cable connection. The mixed 2+2 arrangement has 2 contacts rated at 10A and 2 at 2A. The B series also has 2 through to 6 way versions all with 2A contacts.

Smiths Interconnect opens a new


qualification and test laboratory in Dundee The Centre of Excellence will offer a one-stop-shop to the global customer base for the certification of products used in space applications


Smiths Interconnect proudly celebrated the Grand Opening of its new Qualification and Test laboratory in its site in Dundee, Scotland.


The new laboratory offers a one-stop shop for critical qualification and testing of Smiths Interconnect’s products in Europe. The structure is equipped with in-house multipaction testing and SRS mechanical shock testing system, both in dedicated and environmentally controlled areas.


The Dundee facility can now replicate deep space in terms of vacuum and heat

with high power amplifiers and vacuum systems. It can therefore analyse high power devices that are used in space with regards to their breakdown voltage behaviour in a vacuum or near-vacuum environment. This effect, called multipaction, can render a device useless and, thus degrades the reliability of the satellite.


www.smithsinterconnect.com Extension of miniature cooling aggregates


The so-called miniature cooling aggregates are very efficient and reasonable to use for dissipating heat in larger amounts in smallest space. The combination of a fin structure, optimized in terms of flow technology, in connection with powerful fans leads to a significantly greater heat dissipation per volume unit than natural convection. To this end, Fischer Elektronik is expanding its existing product range of miniature cooling aggregates with the LAM 6 and LAM 6 K design. The new versions have the dimensions 60x60mm and are available for transistor screw mounting or special clip mounting. The basic profile of the miniature cooling aggregates consists of one piece and is manufactured using the aluminum extrusion process. The basic structure of the individual cross sections consists of a circumferential rectangular base frame with a material thickness of 5.5 mm, which also serves as a component mounting surface.


For better heat dissipation of the power loss arising on the device, the semiconductor mounting surfaces on the back, which means inside the closed channel structure, have an additional cooling fin geometry. This absorbs the heat given off by the device and dissipates it to the inner air of the chamber structure. The axial fans, which are adapted to the channel structure of the aluminum profile, are of very high quality and can be installed in mounting holes which are already integrated in the profile. The new miniature cooling aggregates LAM 6 and LAM 6 K are optionally available with the fan voltages 12V, 24V and 48V, depending on the customer's requirements. On the LAM 6, device assembly is made by using the classic screw mounting using additional threads, or on the LAM 6 K using so-called snap-in transistor retaining springs.


Designs of the LAM K series contain a special groove geometry in the lateral semiconductor mounting surfaces, which means that the device can be securely and quickly attached to the semiconductor mounting surface using snap-in transistor retaining springs that are also adapted to the geometry. The respective contact pressure achieved by the springs provides an optimal heat transfer between the device and the unit. The universal snap-in transistor retaining springs THFU 1-7 have been developed for the transistor designs TO 218, TO 220, TO 247, TO 264 and various SIP Multiwatt as well as hole- free power transistors. After installing the snap-in transistor retaining spring, regardless of the type of mounting, the spring stays in place and fixes the transistor on the mounting surface with high contact pressure. Falling out in the transverse direction is not possible due to the overall construction. Additional mechanical CNC processing, modifications or special designs and surfaces are realized according to customer-specific specifications.

www.fischerelektronik.de Problem solved: Discontinued passives and


long lead times with current components To help engineers and buyers in the Electronic Components Industry with End-of-Life (EoL) issues and today’s long lead times for current products, BEC Distribution has announced the availability of direct alternatives to TOKO/Murata, Coilcraft, Vishay and Sumida lines, with short lead times of 6-8 weeks, where most manufacturers are currently working on 16-30 weeks.


BEC’s range of EoL replacements and pin-for-pin replacements for current passives includes: shielded power inductors, multi-layer ceramic chip inductors, radial peaking coils, open wire-wound chip inductors and thin-film chip inductors.


Typically, large component manufacturers discontinue product lines after 5-10 years. This can have a potentially disastrous impact on customers whose products have longer expected lifetime eg Aerospace, Medical, Surveillance or Defence industry equipment. The availability of BEC’s component replacements will far exceed 10 years.


BEC Distribution’s EoL component supplies will be a lifeline to R&D engineers and buyers, where components have been designed into their product lines. With a stock of 15m passive components and franchised distribution agreements with quality alternative component manufacturers, BEC can provide high quality, pin-for-pin direct replacement or alternatives. If the required components are not in stock, then BEC will track down and source matching alternatives, ensuring that EoL issues will not hinder customers’ projects.


With support from BEC, engineers and buyers alike can plan ahead right from the beginning when components are first used or when they are designed-in, ensuring that EoL does not necessarily mean end of supply or support.


BEC Distribution offers drop-in alternates for most manufacturers including Toko, Sumida, Murata, TDK, Coilcraft, Cooper, Bourns, Vishay, Wurth… etc.
