The C1Q 4 is a surface mount fast-acting chip fuse from Bel Fuse's C1Q series. Rated for 4A continuous current with voltage ratings of 125VAC and 63VDC, it features a fast blow response time suitable for protecting sensitive circuits. With an interrupting rating of 100A AC and 50A DC, it can safely clear fault currents. The fuse has a nominal cold resistance of 0.028Ω and a melting I²t of 0.038 A²s. It is housed in a 1206 (3216 metric) package, measuring 3.20mm x 1.58mm x 0.58mm, making it ideal for compact SMD designs. Operating temperature range is -55°C to 125°C. The C1Q 4 is RoHS, REACH, and halogen-free compliant, and approved by CE, CSA, and cULus. Typical applications include notebook computers, LCD monitors, power supplies, and DC-DC converters.
