Bourns SF-3812TM-T SinglFuse Telefuse Telecom Protectors

Bourns SF-3812TM-T Series SinglFuse Telefuse Telecom Protectors are designed for low current protection with high surge tolerance in telecommunications circuits. These fuses use a ceramic tube structure in an EIA 3812 surface mount package and provide controlled opening behavior for line interface protection. The SF-3812TM-T protectors meet Telcordia GR-1089-CORE and UL 60950 overcurrent requirements and support AC power fault and lightning surge coordination standards. These devices offer rated currents from 0.50A to 2A with defined resistance, I²t, and interrupting ratings across AC and DC systems.
