S501-1-R – TBC

The S501-1-R is a Bussmann series fast-acting (F) fuse, conforming to RoHS standards, designed for circuit protection applications. Its current rating is 1 Ampere. This fuse is intended for use in circuits where rapid response to overcurrent conditions is critical. The “S501” designation likely refers to a specific Bussmann fuse series characterized by defined dimensions, voltage rating (which must be determined from supplementary datasheets or testing), and interrupting capacity. Engineers should consult the appropriate Bussmann datasheet to ascertain the precise voltage rating, breaking capacity, I²t value (melting integral), cold resistance, and applicable safety certifications (e.g., UL, CSA, VDE) before incorporating the S501-1-R into a design. Proper application requires consideration of the fuse’s derating factor based on ambient temperature and pulse characteristics of the protected circuit.
