NEW Surface Mountable 5mm Glass Fuse Holders

 

A new SMT Fuse Holder has been introduced which specifically allows standard 5 × 20 mm glass cartridge fuses to be mounted directly onto the surface of a PCB.

 

Designed to meet the rigorous demands of modern high-density circuit boards, this new component combines robust overcurrent protection with the efficiency of automated manufacturing. Rated for up to 10 Amps, 500 VDC, these new holders secure space on printed circuit boards without manual soldering.

 

These new Keystone holders are designed to bridge the gap between traditional glass fuse reliability and modern SMT production lines. Holders feature a durable PA9T UL94V-0 base with specially tensioned Tin-plated, Brass contacts enabling low contact resistance with optimal performance while ensuring the fuse remains securely fastened against severe vibration and mechanical shock..
