High-current jumpers handle up to 7 A

October 20, 2021 By Redding Traiger

Electronic circuits frequently require zero-ohm jumpers for ease of manufacture or to make trace routing easier. Some of these applications require current handling that exceeds the capabilities of general-purpose or high current jumpers. Stackpole’s HCJ series offers more than double the current rating of comparable high current jumpers. The HCJ current ratings range from 5.8A for […]
