1. The superiority of film capacitor temperature characteristicsThe good temperature characteristics of the film capacitor, unlike the other capacitors, are that the dielectric material is a high temperature polypropylene film, and its temperature characteristics allow it to swim back and forth betw

1. What does a varistor mean?A: Refers to the voltage across the varistor at the specified temperature and DC (typically 1 mA or 0.1 mA). 2. What is the reason for protecting the varistor?answer:(1) Distinguish between power protection, signal lines, and varistor for data line protection. They must

Once the rated power exceeds 500W, the shortcomings of passive circuit solutions become very obvious. If the ICL is always in series with the load, the power loss it introduces can be very large. The higher the rated power of the device, the longer the typical working time, and the more obvious the

Dielectric strength refers to the ability of a capacitor to withstand a dielectric. It is defined as the large voltage that a unit thickness is subjected to when the sample is broken down, expressed as volts per unit thickness. The greater the dielectric strength of a substance, the better its quali

1. Rated voltageThe rated voltage refers to the voltage value applied across the capacitor that the film capacitor can operate normally, stably, and reliably for a certain period of time in the circuit. The rated voltage is not only related to the dielectric structure of the capacitor, but also rela

The varistor is generally used in parallel in the circuit. When the voltage across the resistor changes abruptly, the short circuit of the resistor blows the current fuse to protect it. Varistors are used in circuits and are often used for power supply overvoltage protection and regulation. The reli

Although most NTC thermistors are typically suitable for use in the temperature range of -55 ° C to 200 ° C and provide accurate readings, the special series of NTC thermistors can be close to zero (-273.15 ° C) and Those designed for use above 150 °C. The temperature sensitivity of the NTC sensor i

1. Fuel injectionMost occur in high-voltage capacitor banks without internal protection components due to internal phase-to-phase shorts or relative case breakdown.The treatment can be installed with internal protection components to allow the capacitor to be removed from the grid before it occurs;

The effect of applied voltage on the self-healing properties of the film capacitor: in order to achieve self-healing, there must be a certain amount of action at the surrounding breakdown point to form a solid-opening zone where the metal is removed, but if the amount of release is too much, the adj

The main parameters of varistor are nominal voltage, voltage ratio, control voltage, residual voltage ratio, current capacity, leakage current, voltage temperature coefficient, current temperature coefficient, voltage nonlinear coefficient, insulation resistance, static capacitance and so on. Genera
