SAMPLING NOW: Passives for Power plus new 3-in-1 LED Combi Light
Replacement shunt resistors guarantee performance
Any size, any shape SMPS ceramic capacitors
3-in-1 standard, emergency and blackout LED Combi Light


Replacement shunt resistors guarantee performance
With performance guaranteed to meet the rated specification, Powertron FHR series resistors can replace existing current-sensing resistors to improve the reliability of high-power precision applications in the medical, scientific, military and industrial sectors.

Available in 2- and 4-terminal versions, the FHR series offer power ratings from 5W to 2500W and achieve load stability of 0.1%, with a temperature coefficient of resistance (TCR) of ±15ppm/k. Tolerances are available to 0.1%.

Any size, any shape SMPS ceramic capacitors
AMC multilayer ceramic capacitors can be manufactured in packages and footprints which accurately match the available board-space, whilst stacked versions, with a standard rectangular footprint, enable high levels of volumetric efficiency, combined with low ESR/ESL characteristics at high switching frequencies. J- and L-bend surface-mount or through-hole terminations also help to minimise manufacturing stress.

The Variable Pitch versions can achieve more than 25% improvement in volumetric efficiency with optimum use of the available space, and are created by AMC directly from customers’ mechanical designs and electrical parameters.

Stacked versions are available with capacitance values to 900μF and offer a wide operating temperature range of -55˚C to 125˚C, or up to 200˚C for some ranges. They are suitable for use in input/output filters, snubbers and coupling in SMPSs with voltage ratings from 25V to 5KV. J and L-bend surface-mount or through-hole terminations also help to minimise manufacturing stress.

3-in-1 standard, emergency and blackout LED Combi Light
Oxley Combi Lights integrate 3 LED lighting modes into a single fitting with a profile of just 20mm. In white mode, the Combi Light provides standard, dimmable illumination powered by a 100/230V AC input; the blackout mode uses the same power source and is triggered by a signal to eliminate residual glare by switching to red light, or other colour options. The emergency mode uses separate LEDs powered by a rechargeable battery.

Applications for the Combi Light include ground-control stations, as well as military shelters and forward command positions.
