The new HVC series high voltage chip resistors from Ohmite offer high voltage capability in a surface mount package. Meeting MIL-STD-202 specification, the HVC series uses the latest thick film technology to meet voltage applications of up to 3kV.

Bridging the gap between low power, high resistance potentiometers and high power, lower resistance wirewound rheostats, Ohmite’s new PE Series thick film potentiometers have a metal shaft and ceramic housing to provide a smooth linear operation and low noise performance.

Cherry will present its new range of automotive modules at the Southern Electronics exhibition which takes place at Thorpe Park on February 8th & 9th. The company will also exhibit switches and controls, including its DZ switch, for non-automotive applications.

knitter-switch now offers the widest range of toggle switches available to designers Worldwide. Switches are available for practically every application in industries such as electrical panel building, instrumentation, audio/broadcast, telecomms and board level products.

Specifically designed for EMI suppression of high frequency circuits, the latest range of air core chip coils from Murata is fully compliant with RoHS legislation and available immediately in full production volumes.

A new non-mechanical switching system has been developed by Wessex Advanced Switching Products (WASP) and has already been specified by a leading aircraft seat manufacturer. The capacitive switching system has been incorporated in the control system for a new and sophisticated range of seats being used by a major airline in their new Airbus A340 aircraft.

The latest surface-mountable AVX CANBus varistors replace three components typically used to protect against transient voltage spikes: two back-to-back Zener diodes and an EMC capacitor in parallel.

Niobium oxide and tantalum capacitors, manufactured by AVX, provide high capacitance performance in audio applications. Delivering a clear and rich flow to headphones and speakerphones, the parts realise the low frequency response demanded by high quality audio equipment.

AVX has introduced a low-profile TAJ lead-free “R” (0805) case size tantalum capacitor. Achieving high capacitance values, the device allows design engineers to reduce the size of their systems by downsizing components, or by reducing the amount of components needed in a circuit.

The SCHRACK RT1 power PCB relay from Tyco uses a bifurcated (twin) contact system and is specifically designed for switching from dry circuit up to 16A, including arc-less switching.
