Stackpole's WWP Series of wirewounds offers guaranteed pulse handling for high energy handling requirements. Standard wirewounds exhibit variable pulse handling due to materials flexibility and trimming processes.
The WWP Series defines the element wire as robust as possible and does not require trimming. The result is a thru-hole wirewound series with outstanding pulse handling that is very reliable and consistent and more repeatable than pulse handling film resistors.
The WWP is available in 3-, 5-, 7-, and 10-W power ratings. The exceptional energy ratings for the WWP are as follows: WWP3 energy ratings up to 35J; WWP5 energy ratings up to 75J; WWP7 energy ratings up to 160J; and WWP10 energy ratings up to 580J.
The WWP is designed for a wide range of power supply applications, LED lighting, motor controls, metering, and appliances and white goods.
Pricing for the WWP depends on size and resistance value. Contact Stackpole or a franchised distribution partners for specific pricing.
