The SP3A Series from Stackpole are axial leaded 3W wirewound resistors designed for applications requiring good surge handling and fusibility to prevent fire or significant heat generation. The SP3A resistors can survive hundreds of 3KV surges of less than 50 microseconds without failing or significantly shifting resistance. Additionally, the SP3A resistors will fuse quickly and without flame or significant heat when subjected to continuous overloads of 120VAC or more. Stackpole's proprietary design allows for fast fusing without sacrificing short-term pulse handling.

The SP3A Series UL-recognized part (file no. E344795) is available in resistance values from 10 ohms up to 100 ohms.  Other non-UL recognized values and sizes may be available.
