The vertical mount ceramic housed wirewound series from Stackpole has added 7 and 10W sizes. In addition, the vertical mount package reduces the amount of heat forced into the PCB, allowing applications to run at cooler temperatures. Finally, the ceramic and cement package is flameproof, an important feature for applications requiring power resistors.

The wirewounds are suitable for power supply and motor protection in appliances which have limited board space, but a large amount of headroom, claims the company. Other applications include robotics, wind energy inverters, UPS systems, remote telecomms and datacomms power supplies, welding equipment, and plasma cutting equipment.
