Passives

Raychem Circuit Protection, a business unit of Tyco Electronics, has announced the introduction of its PolySwitch LVR series of resettable circuit protection devices. PolySwitch LVR devices help protect electric motors and transformers used in commercial and home appliances from failures caused by mechanical overloads, overheating, stall, lost neutral and other potentially damaging conditions.

New from Foremost Electronics is a range of short-travel haptic switches which, having the option of an integral LED, are ideally suited to a broad spectrum of switched control applications, such as in an automotive steering wheel which typifies its current use.

Groundbreaking patented technology and intelligent design have allowed passives specialist AVX to develop a number of exciting new electronic component devices in 2006 such as FLEXISAFE Ultra Safe capacitors for high protection against mechanical cracking issues; 2-terminal Land Grid Array capacitors that offer Equivalent Series Inductance similar to 8-terminal IDCs; and CoreCap capacitors that deliver Equivalent Series Resistance down to 3mΩ a...

Recently added to Tyco Electronics’ CGS range of power resistors, new aluminium housed THS series power resistors are based on the high performance HS series devices, featuring same basic performance levels but at lower costs.

A new method of heatsinking has been developed by Ohmite which is proving popular with design engineers because it solves the problem creating a gap if the screw is overtightened when installing conventional TO-220 resistors and creates optimal thermal transfer between the resistor (or semiconductor) and the heatsink.

Lorlin Electronics, the UK’s longest established switch manufacturer, is pleased to announce the availability of its wide range of coded rotary switches for control and programming functions.

Now available from TTI Europe, the world’s leading authorized specialist distributor of passive, connector and electromechanical components, Raychem Circuit Protection’s PolyZen™, a polymer-enhanced, precision Zener diode micro-assembly, is designed to meet the growing need for over-current and over-voltage protection on portable equipment that uses barrel jacks for DC power input. PolyZen helps protect sensitive electronics from damage...

The main target applications for the Schrack 410 83 power relays from Tyco Electronics are safe power supply disconnection - for example in photovoltaic inverters, washing machines and tumble dryers. The devices feature one pole (16A, 1 NO bridging contact) and have a contact gap of 3mm and low coil power of only 360mW. Quick connect terminals for load side ensure fast and easy mating.

Semtech has announced the uClamp 0524P, the first 5V electrostatic discharge protection device with a flow through design. The four-line device is ideal for portable systems and replaces four separate discrete components, saving both cost and board space.

New from RF and microwave component specialist Link Microtek are three series of miniature electromechanical RF switches that have been designed for use in 1-slot VXIbus modules and other applications where space is restricted.
