Schurter Non-Resettable Fuse 3A, 125 V AC, 125 V DC Super Quick Acting Ceramic Body 3-103-122

Schurter 3-103-122 non-resettable fuse delivers reliable circuit protection with a 3 ampere current rating suitable for sensitive electronic devices. It supports a dual voltage rating of 125 V AC and 125 V DC, enabling its use in diverse electrical systems requiring stringent fuse response.

Constructed with a durable ceramic body, this fuse sustains high operating temperatures up to 125°C and offers consistent performance under harsh environments. Its super quick acting (FF) fuse characteristic rapidly interrupts circuits during fault conditions, helping prevent damage from overcurrents.

The fuse package adheres to a 1206 SMD size with compact 1.55 mm width and height, and 3.2 mm depth allowing compatibility with standard surface mount assembly processes. It features tin plated nickel terminals enhancing durability and conductive reliability.

This non-resettable fuse is hermetically sealed, eliminating tin whiskers and dendrites risks and ensuring long-term stability. With a high breaking capacity rated at 50 A and a maximum rating of 300 A at 125 V DC, it is suitable for demanding industrial and aerospace-grade applications.

Applications include avionics, defense, medical equipment, and space-grade electronics where performance and safety standards are critical. The fuse complies with international regulatory standards including REACH, CSA, CE, RoHS, and UL 248-14 demonstrating broad global acceptance.
