TeleLink Fuse
TeleLink Surface Mount (SM) surge resistant fuse offers circuit protection without requiring series resistor. When used conjunction with SIDACtor Transient Voltage Suppressor (TVS), TeleLink fuse SIDACtor provide complete regulatory-compliant solution standards such 1089, TIA/EIA-IS-968, 60950, K.20 K.21 (formerly known Part 68). series resistor required F1250T F1251T comply with these standards. Contact factory enhanced K.20 K.21 details.
