The 170M5412 from Littelfuse is a high performance midget Class CC fast blow metal-body fuse. It is specifically designed for reliable over-current protection of circuits with medium overload impulses and short-circuit currents. Its compact 5mm x 20mm size makes it ideal for applications where a space-saving design is critical. The 170M5412 offers superior performace with its current rating of 12A and its voltage rating of 300VAC/VDC.

The 170M5412 has a wide range of uses within the field of electrical circuitry. It is the preferred product for high inrush current circuits, due to its low I2t values, which gives it the ability to tolerate short-duration current bursts without loading or damaging the circuit it protects. It is suitable for use in a large variety of over-current protection applications, including consumer electronics, automobiles, industrial control systems, solar/photovoltaic systems, telecoms and LED lighting.

The working principle of the 170M5412 is relatively simple. It comprises an all-metal shell with a body made from silver zinc, featuring a fusible metal element within it. When the circuit it is protecting is overloaded or a short circuit occurs, the fusible element melts, disrupting the flow of electricity through the circuit and thereby preventing any further damage to it.

The 170M5412’s all-metal construction and reliable operation make it the ideal choice for use in medium-voltage and high inrush current applications. Its compact design also makes it suitable for use in tight spaces. Its performance and features make it an excellent choice for use in a variety of electrical circuitry protection applications.
