Pin Header Shunt Jumper — Black, 2.54mm, 10-Pack
2.54mm pitch pin header shunt jumpers in black — pack of 10. A shunt jumper (also called a jumper cap or jumper block) is a small connector that short-circuits two adjacent pins on a pin header to select a configuration option. Used on Arduino bootloader selection headers, BIOS configuration jumpers, power selection headers, and PCB configuration jumpers. The most fundamental configuration component in electronics.
Key Specifications
- Pitch: 2.54mm (fits 2 adjacent pins)
- Color: Black
- Contact: Tin-plated brass
- Current rating: 3A
- Pack: 10 shunts
- Compliance: RoHS compliant
Why Keep Shunts in Stock?
- ✅ Configuration selection — select voltage, bootloader, and interface options on PCBs
- ✅ Easy to lose — 10-pack ensures you always have spares
- ✅ Universal 2.54mm — fits all standard 2.54mm pin headers
- ✅ 3A rated — suitable for power selection jumpers
Typical Applications
- Arduino bootloader and clock selection jumpers
- BIOS and motherboard configuration jumpers
- Power supply voltage selection headers
- PCB interface and mode selection jumpers
- Hard drive and optical drive master/slave jumpers
