So I'm not sure if it is a varistor or if it just has obscure markings. The markings are : 05 K385 1146 I know the k385 is the voltage from what I can find, but have no idea what the current is or what part number it matches up with.
A varistor is an electronic component that protects expensive devices from harmful power surges, much like a shock absorber. For example if there is a power surge, the varistor, normally having a very high resistance, responds to the voltage spike by absorbing its energy with a very low resistance.
varistor works as a capacitor. However, when the surge voltage exceeds the varistor voltage, the impedance across the varistor terminals decreases sharply. Since input voltage to the circuit depends on the varistor internal resistance and line impedance, the decrease in the impedance across the varistor terminals allows surge voltage suppression.

Mu503 varistor datasheet
Varistors vary quite heavily between different models. For example, a metal oxide varistor has a different build than a series built out of crystals. The series of a varistor varies depending on the voltage it can hold, the devices it is used to control, and the type of power used in its build.SpiMLV is an online engineering tool that defines the voltage-current characteristics and frequency response for AVX SMD and leaded multilayer varistors. Main features include easy part selection based on parameters, datasheets, interactive charts of voltage - current characteristics, S21 frequency response, power derating curve and ESD rating.A varistor is a voltage dependent variable resistor, of which a MOV is one type. A crude way to simulate is back to back zener diodes for bi-directional or a single zener for unidirectional. If you need more precise simulation then you should first check for a model from the manufacturer for the actual part you are using. information in the datasheet); these curves guarantee a maximum varistor voltage change of ± 10 % at 1 mA. MAXIMUM ENERGY During the application of one pulse of current, a certain energy will be dissipated by the varistor. The quantity of dissipation energy is a function of: • The amplitude of the current d. In terms of EMC elements, gas discharge tubes (GDT), metal oxide varistors (MOV), X-capacitors, and differential mode chokes are low-frequency elements, and common mode chokes, Y-capacitors and Electro Spark Detectors are high-frequency elements. 3) Differential Mode and Common Mode.
