The key characteristics of ceramic resistors involve structure, material characteristics, power, power density and particle conductive solid core structure. The resistors absorb energy uniformly and conduct electricity as a whole without wire failure.

Resistor is made of some materials which hinder the current. It is one of the most basic and commonly used electronic components. Resistor has many uses in the circuit, which can be summarized as reducing voltage, distributing voltage, limiting current and providing necessary working conditions (voltage or current) to various components. For convenience of expression, resistor is usually referred to as resistance.
