Varistor, MOV and other transient voltage suppression (TVS) devices have become integral components to provide electrical transient protection to delicate, expensive and sometimes even safety critical equipment. One such device is AVR-M2012C220KT6AB manufactured by Avago Technologies, which is a multilayer ceramic capacitor with NTC thermistor.

The AVR-M2012C220KT6AB is a transient voltage suppression device that combines a multilayer ceramic capacitor (MLCC) and a negative temperature coefficient (NTC) thermistor. It has a wide working temperature range of -55°C to 125°C and a wide sensing voltage range of 6.5V to 16V. The AVR-M2012C220KT6AB was designed to protect electronic equipment from over-voltage transients such as lightning and power surges. Its combination of MLCC and NTC thermistor provides a robust protection circuit with the device responding rapidly and with low clamping voltage.

The AVR-M2012C220KT6AB can be used in a wide range of applications such as consumer electronics, lighting controllers, industrial control systems, medical and automotive electronics and more. In consumer electronics, the AVR-M2012C220KT6AB can be used to protect expensive equipment such as home theatre system, game consoles, high-end televisions and other delicate electronic equipment. In lighting controllers, the AVR-M2012C220KT6AB can be used to prevent voltage fluctuations from affecting lighting systems and other connected electronic devices. In industrial control systems, the AVR-M2012C220KT6AB can be used to protect expensive industrial devices from electrical transients. In medical and automotive electronics, the AVR-M2012C220KT6AB can be used to protect delicate circuits from voltage transients caused by power surges.

The working principle of the AVR-M2012C220KT6AB is based on the combination of MLCC and NTC thermistor. The MLCC provides a low capacitance for suppressing high-frequency peak voltage transients. The NTC thermistor is used to absorb a portion of the energy, and it absorbs less energy as it heats up. The device also has a very low series resistance, providing fast response and low clamping voltage. This helps to reduce the effect of potential voltage spikes and protect the connected equipment from possible damage.

Overall, the AVR-M2012C220KT6AB is a robust and reliable transient voltage suppression device with wide working temperature range and sensing voltage range suitable for a wide range of applications. It also has the added advantage of having a fast response time and low clamping voltage, which makes it effective in protecting delicate circuits from over-voltage transients safely and reliably.
