87063-050

Varistors, or voltage dependent resistors, are designed to absorb transient voltage events in electronics circuits. Their function is similar to that of a fuse in an electrical circuit, but their properties make them more durable and more efficient in today’s fast-paced electronics world. The 87063-050 is a type of varistor that is specifically designed for high-energy circuit applications. This article will explain their application field and working principle.

87063-050 Application Field

The 87063-050 was developed to address a demand for high-powered electronics in the industry. Its application field is quite broad, and includes high-power circuits in telecommunications, automotive, and aerospace industries. Key features of the 87063-050 include a voltage dependent resistor rating of up to 85V, a holding current of 600A, and a high surge current rating up to 200kA. Due to its versatility and range of applications, the 87063-050 can be used in a variety of circuits, from basic power and data sources to complex digital systems.

87063-050 Working Principle

The 87063-050 works in a similar way to other varistors. It absorbs transient voltage events, or spikes, in an electronic circuit, which can cause circuit failure and component damage. When a voltage event is detected, the 87063-050 works by quickly diverting the excess energy away from the circuit, thus preventing damage and preserving system integrity.

The 87063-050 contains a high-resistance ceramic element, as well as a proprietary metal layer, which functions as an “electric fuse”. The ceramic element absorbs the transient voltage, while the metal layer conducts the excess energy away from the circuit. This combination of ceramic and metal elements safely dissipates the surge energy to an external routing device, such as a capacitor.

The 87063-050 can provide effective protection against transient voltage events, while still allowing signals to pass through the circuit. This enables the device to be used in a wide range of applications, such as in telecommunications, automotive, and aerospace industries. In addition, the 87063-050 is suitable for use in high-power circuits, as it can withstand up to a 600A holding current.

Conclusion

The 87063-050 is an excellent example of a modern voltage-dependent resistor. Its high-resistance ceramic element, combined with a proprietary metal layer, enables it to absorb transient voltage events and effectivelyconduit the excess energy away from the circuit. The 87063-050 is suitable for use in a variety of applications, from basic power and data sources to complex digital systems, and can withstand up to a 600A holding current.
