BK/GMC-100-R is a medium time-delay glass tube fuse designed for circuit protection in electronic applications. This fuse features a 5 mm x 20 mm physical size with a nickel-plated brass endcap construction and is rated for 100 mA at 250 Vac. The fuse exhibits a typical DC cold resistance of 35 O and a maximum voltage drop of 0.0094 mV at rated current, with a typical pre-arc time of 10,000 cycles. It is RoHS compliant, halogen-free, and designed to UL/CSA 248-14 standards with UL and CSA certifications. The GMC-100-R is commonly used in consumer electronics, industrial equipment, and power distribution systems where reliable overcurrent protection and medium time-delay characteristics are required.
