The Littelfuse 0501020.WR is a 20A, 32V surface mount ceramic fuse from the 501 Series, designed for high current over-current protection in demanding environments. It features a fast-acting (fast-blow) response time suitable for circuits requiring quick interruption of overcurrents. The fuse is housed in a 1206 (3216 metric) package and is fully compatible with surface mount assembly processes.
Electrically, the fuse offers a breaking capacity of 150A at 32VDC, ensuring reliable fault interruption. Key electrical characteristics include a nominal resistance of 0.00194 ohms, a nominal melting I²t of 86.360 A²sec, and a nominal voltage drop of 0.05888V at rated current. The power dissipation is 1.1776W at rated current. The fuse operates over a wide temperature range from -55°C to 150°C, making it suitable for high-temperature applications.
This fuse is 100% lead-free, RoHS compliant, and halogen-free. It holds CSA and UL agency approvals. The ceramic construction provides excellent temperature stability and performance reliability. Typical applications include voltage regulator modules (VRM), notebook PCs, and DC-DC converters.
