Introduction to Fuses

Fuses are an important part of electronic circuits and systems. They protect components from being damaged by power surges and shorts. Fuses may be rated with a voltage and amperage rating that cannot be exceeded without damaging the fuse. Some fuses are also designed to react quickly to high-current events.

CC12H375MA-TR Application Field and Working Principle

The CC12H375MA-TR is a surface-mount, 12V, 375mA and 125VAC fuse manufactured by Amphenol Advanced Sensors. This fuse is specifically designed for low and mid-voltage applications with a dual-element, time-delay structure. The time delay feature helps to protect the circuit from a short-term overload, while still providing enhanced multi-strike and surge capability.The element of the CC12H375MA-TR is composed of a nickel strip and a tin-plated steel strip. When the voltage across the fuse exceeds the rated voltage, the steel strip melts and creates a temporary short circuit, thus limiting the current flowing through the fuse. However, due to the low melting temperature of the tin-plated steel strip, the fuse is able to withstand repeated use, allowing it to offer a higher degree of protection than traditional fuses. The CC12H375MA-TR is intended for use in many different applications. It is ideal for use in consumer electronics, automotive applications, office equipment, instrumentation and other electronic systems. It is the preferred fuse for applications that require a high current rating, low voltage rating and time-delay feature.

Conclusion

The CC12H375MA-TR is a high-performance fuse manufactured by Amphenol Advanced Sensors. It is ideal for applications which require a high current and low voltage rating, as well as a time-delay feature. This type of fuse offers increased protection from short-term overloads and surges, and is suitable for use in a variety of consumer electronic, automotive, instrumentation and office equipment applications.
