The SS-5H-1A-AP is a 1 A, 250/300 V subminiature radial-leaded time-delay fuse designed for primary and secondary circuit protection in consumer and industrial applications. It features a high breaking capacity of 100 A at rated voltage, a typical DC cold resistance of 78 mO, and a typical melting integral (I²t) of 7.4 A²s, with a typical voltage drop of 94.5 mV at rated current. The fuse is housed in a plastic cap and base with UL 94V0 flammability rating, is halogen-free and RoHS compliant, and is designed to IEC 60127-3 standards. It withstands high-frequency vibration per MIL-STD-202F Method 201A and operates across -40 °C to +125 °C with proper derating. Common applications include power supplies, notebooks and laptops, appliances, lighting ballasts, power adapters, set-top boxes, LED/LCD televisions, air conditioners, and battery chargers.
