Stackpole offers 7W, 10W wirewound resistors

Stackpole Electronics Inc. has included 7W and 10W sizes in its line of vertical mount ceramic-housed wirewound resistors—the VM series. The devices provide high power handling and decreases board space, the company stated. The vertical mount package also reduces the amount of heat forced into the PCB, allowing applications to run at cooler temperatures.

In addition, the ceramic and cement package is completely flameproof, an important feature for many applications requiring power resistors. The VM is a popular choice for power supply and motor protection in appliances that typically have limited board space, but a relatively large amount of headroom, Stackpole added. Other applications that use this type of device include robotics, wind energy inverters, UPS systems, remote telecom and datacom power supplies, welding equipment and plasma cutting equipment.

The VM Series is available in bulk packaging ranging from 250–1500 pieces depending on size. Pricing varies with size and ranges from $0.10 to $0.30 each in minimum quantities.
