ELECTROLYTIC CAPACITORS


The high ripple current, large can, QP and WP series of high reliability electrolytic capacitors has been introduced by Components Bureau, for alternative energy solar PV inverter applications. Manufactured by Jamicon, the two new series are available with a large number of capacitance values, with ripple currents as high as 40A (rms) at 85°C, 120Hz. This series offers 2,000 hours life at 85°C,


THERMALLY CONDUCTIVE MATERIAL OFFERS HEAT TRANSFERABILITY


Henkel Adhesive Technologies has developed a thermally conductive material with the ability to transfer heat through the encapsulating layer. These thermally conductive products offer dual-function performance in a single material solution and are offered as an alternative to multi-step, messy potting processes. Because they can be melted, moulded and cooled quickly under low pressure, they deliver an encapsulation technique that provides a high throughput solution for protection of delicate circuitry and PCB assemblies, while forming a self-enclosed housing. These inherent Technomelt advantages are now expanded with the addition of thermal conductivity to enable heat dissipation. "Thermal control is one of the biggest challenges for today's electronic products," says Art Ackerman,


Henkel Global Product Manager for Circuit Board Protection Materials. "For certain applications, adding another layer of heat transfer only serves to improve reliability and long-term performance, which is the objective of this new Technomelt platform." The first commercialised material in the novel Technomelt portfolio delivers a thermal conductivity of more


than 0.5W/m-K and is well-suited for applications such as LED drivers, power supplies, solar inverters, camera modules and automotive electronic power systems, among others. In testing, the material has shown a 40°C component temperature reduction as compared to standard Technomelt, effectively diffusing heat from its source. Uniquely formulated for moulding techniques, the new Technomelt materials draw on Henkel's broad knowledge of hot melt resin and filler technology to deliver a melt viscosity that is compatible with standard low pressure moulding processes and equipment. Filler dispersion is maintained for long periods of time at melt temperatures above 180°C.


“Current and next-generation product designs will continue to need more material capability than ever before," concludes Ackerman.

High current capable screw connections are made via M5 bolts, (M6 for the 90mm diameter case). Multiple working voltages can be


selected in the industry standard values from 160Vdc to 550Vdc (500Vdc for the WP), capable of withstanding surges voltages of up to 600Vdc. www.componentsbureau.com


Farnell element14 has expanded its portfolio of AEC-Q200 qualified products with the addition of the newest passive components from AVX, Bourns, Kemet, Murata, Panasonic and Vishay, which include capacitors, resistors, inductors and other passives.


AEC-Q200 qualified passives have been designed for automotive electronics applications where reliability and stability are required in challenging conditions of high temperature changes, pressure resistance, humidity and mechanical stress. www.farnell.com


NEW REVOLUTIONARY FANLESS POWER SUPPLY FOR INDUSTRIAL AND MEDICAL APPLICATIONS


The CoolX600 Series is the new, revolutionary, convection-cooled modular power supply platform from Excelsys Technologies, which delivers 600W without fan assisted cooling from a compact 8.5 x 4.5 x 1U package. This solution offers a very good level of efficiency and reliability in addition to a comprehensive feature set and specifications. The power supply comes with a five year warranty ensuring reliability. Key features and options include 600W output


with natural convection cooling, no fan/airflow required. This results in higher system reliability, with typically 25% longer lifetime than competitors. In addition, the CoolX600 features conversion efficiencies of up to 94%. The device


/ ELECTRONICS


is claimed to provide higher input surge protection of 4KV Line to PE for operation in harsh environments, reverse energy protection without the use of external blocking diodes as well as safety certified operation at altitudes of up to 5000m. A 24W, medically isolated, auxiliary supply is available as a standard feature, offering effectively another output for system intelligence, control, displays etc. This power supply is available with full safety


certifications to IEC60950 2nd edition for industrial applications whereas the CX06M carries IEC60601-1 3rd edition & IEC60601-1-2 4th edition (EMC) for medical applications. www.excelsys.com
