The VM Series from Stackpole has added 7 watt and 10 watt sizes. The VM Series is a vertical mount ceramic housed wirewound series, which provides high power handling while taking up less board space than many other high power resistors. 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 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 which typically have limited board space, but a relatively large amount of headroom. Other applications which use this type of device include robotics, wind energy inverters, UPS systems, remote telecom and data com power supplies, welding equipment, and plasma cutting equipment. The VM Series is available in bulk packaging ranging from 250 to 1500 pcs depending on size. Pricing varies with size and ranges from $0.10 to $0.30each in minimum quantities.
