Non-linear resistor energy storage

What is a non linear resistor?

Non-linear resistors are resistive components where its resistance is not behaving linearly with parameters such as voltage, current (varistors), temperature (thermistors), or it depends to the previous stage (memristors).

What is the difference between a linear resistor and a varistor?

It can be seen that the voltage curve for a varistor is very different to that of a linear resistor. The discharge time for a varistor is much shorter – usually ~30% of the linear discharge time. Metrosil varistors enable superfast energy discharge for high energy applications worldwide.

How reliable are non-linear resistors?

The reliability of non-linear resistors, including varistors, is today regarded as relatively good. It depends on serious manufacturers using SPC-based production programs and having verified type approvals. Examples of climatic category classified products 40/125/56 indicate good quality.

What is non-linear resistance?

The non-linear resistance behaviour is successfully used to get specific features like sensors, limiters, ESD protection, self-balancing temperature stabilisation etc., using still a relatively simple and reliable passive component.

How does a thermistor reduce resistance?

The reduced resistance is achieved by a construction that connects “resistor elements” in parallel inside the thermistor body. NTC stands for negative TCR (Negative Temperature Coefficient). The temperature dependence is strong and exponential and follows the formula: Thermistor temperature dependence equation

What is a memristor resistor?

Varistor and other ESD suppression devices application field vs frequency; source: Panasonic Memristors are non-volatile electrically-adjustable resistors. Made mostly from metal oxides, they scale well and are proposed as memory elements in nanometre-scale logic for future brain-like networks.
