What’s New Comfortable enclosures go large
include in-field test andmeasurement instruments,medical devices, data loggers andmuchmore.
The handheld enclosures feature soft-touch
Teko has extended its Teknet range of ABS enclosures with twelve newmodels featuring more internal space. Rectangular and pulpit models are available. Typical applications
edge grips for secure, comfortable handling and edge protection. Standard casematerial is off-white (RAL 9002) or black (RAL 9004) ABS (UL 94 HB) with a textured finish. Edge grips are in contrasting light grey or dark grey elastomer. Other colours are available.
External dimensions range from155 by 96 by 31mmto 155 by 96 by 55mm. Four
models also feature a standard battery compartment, with clip-on lid, for two or four 1.5V AA cells or one or two 9V cells.
Top and basemouldings include internal
screw pillars. Allmodels have a recessed top moulding for amembrane keypad or product label. Pulpitmodels have an inclined display area for fitting standard LCD displaymodules.
Prices start at £9.

Speedy oscillators
current steering logic oscillators for high volume applications.
The new HCK5361 and HCK5761 oscillators
are claimed to be highly competitive and deliver higher frequencies compared with surface acoustic wave designs. Specifications include jitter performance of less than 1ps (12kHz to 20MHz) and an operating temperature range of -40 to 85°C.
Details common to both ranges include:
Mercury Electronic Components Europe is offering two new ranges of high-speed
frequency range from40MHz to 200MHz; 2.5V or 3.3V supply; typical femtosecond integrated phase jitter of 200fs; and typical ultra-low phase noise of -138dB/Hz at 10kHz offset.
HCK5361 oscillators feature 5.0 by 3.2 by Resistor prices falling
Rapid Electronics has reduced its prices on two ranges of high energy dissipation carbon composition resistors from Arcol.
Totalling over 140 individual lines, the 0.25 and 0.50WRCC series of axial
lead resistors are available from2.2ohms to 910kohms. These solid carbon composition resistors are designed for high pulse capability and energy dissipation. Specifications include five per cent tolerance, peak pulse voltage of 6kV (025 series) and 10kV (050 series) and -55 to 125°C operating temperature range.
The RCC series’ carbon composition design is said to provide better pulse
endurance compared to filmresistors, suiting the components to prototyping, development, circuit assembly and audio applications.
Rapid’s passive components product manager, Richard Philpot, said:
“We are delighted to be able to offer competitive prices on these Arcol resistor lines. They are high quality components which we can offer in significant volumes.”
Price breaks are available across these Arcol ranges, with discounts possible
on bulk orders.

Small supply packs a punch
Powersolve has launched the TMR-3WI series DC/DC converters offering up to 3Wfroma 21.8 by 11.1mmSIP package. Height is 9.2mm.
With an ultra-wide 4:1 input voltage range, these Traco
Power products feature regulated output voltages from3.3 to 15VDC over an operating temperature range of -40 to 85°C.
Said to offer very low ripple and noise levels, the
converters incorporate short circuit protection, remote on/off and input/output-isolation to 1500VDC
