BK/S500-200-R is a fast-acting, low breaking capacity fuse designed to IEC 60127-2 standards in a 5 x 20mm glass tube form factor. The fuse features a 250V AC voltage rating with a nominal current rating of 200mA and a typical DC cold resistance of 0.016O, providing reliable overcurrent protection in electronic circuits. With a typical melting temperature of 1700°C and a maximum voltage drop of 1.7mV at rated current, this fuse delivers consistent performance across a wide range of applications. The glass tube construction includes nickel-plated endcaps for enhanced durability, and the fuse is available with optional axial leads for flexible installation. This fuse is widely used in consumer electronics, industrial equipment, and power distribution systems where fast-acting protection and compact form factor are essential.
