Schurter Non-Resettable SMD Fuse, 5A, 32V AC/DC, Ceramic, Super Quick Acting, 1.55mm x 1.55mm, MGA-A Series, 3-103-130

The Schurter 3-103-130 is a non-resettable surface-mount fuse engineered for robust circuit protection in advanced electronic systems. This component, from the highly regarded MGA-A series, is designed for the safeguarding of sensitive circuits against overcurrent conditions where a reliable, fast-acting response is critical.

Featuring a super quick acting FF characteristic, this fuse is constructed with a durable ceramic body and tin-plated nickel terminals which provide excellent resistance to thermal and mechanical stresses. The device is capable of handling a rated current of 5A and is suitable for use with both 32V AC and 32V DC supplies. It is enclosed in a compact 1206 SMD package measuring 1.55mm × 1.55mm, making it ideal for space-constrained PCBs and high-density assemblies.

With a maximum breaking capacity of 50A at its rated voltage and rated for up to 300A@125VDC (as the series’ peak capacity), this fuse ensures protection of components in the event of fault currents. The operating temperature range is impressive, spanning from -55°C to 125°C, providing stability for environments subjected to varying temperatures.

Schurter's design eliminates tin whiskers and dendrites, ensuring robust, hermetically sealed construction with no leaded coatings, making the fuse RoHS, REACH, and CE compliant. It has been tested and approved under major global safety standards including UL 248-14 and CSA.

This component finds application in industrial automation equipment, medical devices requiring stringent reliability, avionics, defence electronics, and many other sectors where circuit miniaturization and reliable protection are paramount.

Typical use cases include overcurrent protection in power management circuits, input power lines, DC-DC converter protection, medical device interfaces, and defence-grade electronics. Its reel packaging supports automated pick-and-place manufacturing processes.

For engineers and designers seeking a compact, high-reliability SMD fuse for demanding applications, the Schurter MGA-A 3-103-130 offers compliance with critical safety standards and a proven track record of performance.
