Chassis Mount Resistors

A chassis mount resistor is a type of resistor which is designed to mount on the chassis of an electronic device. It is designed to dissipate heat generated by the resistor while also protecting the circuit from potential shorts and wiring errors. Chassis mount resistors are typically used in power supply applications where high currents and/or loads require a greater heat dissipation capacity.

C300KR25 is a type of chassis mount resistor, which is designed to provide a combination of high accuracy, stability, and low thermal impedance. The resistor is composed of a ceramic substrate layer with a metalized pattern on its surface, allowing for a very high power rating as well as good heat dissipation. It also features a temperature coefficient controlled by a thermistor, which allows for improved accuracy and stability in applications where temperature influences the performance.

The C300KR25 application field is mainly used in power supply applications such as lighting, IEEE-802.3af/at/bt, automotive, AC-DC and DC-DC power conversion. In these applications, the resistor is typically tasked with adjusting loading, balancing current or controlling voltage. The features of the C300KR25 make it suitable for use in high-power or high-precision applications.

The working principle of the C300KR25 is relatively simple. When the voltage or current passes through the resistor, a voltage drop is generated across its terminals. This voltage drop is equal to the product of the resistance and the amperage of the current passing through the resistor. By adjusting its resistance, the voltage drop can be adjusted accordingly, allowing for the desired parameters to be achieved in the circuit.

In summary, the C300KR25 is a type of chassis mount resistor designed to provide a combination of high accuracy, stability, and low thermal impedance. It is mainly used in applications such as lighting, IEEE-802.3af/at/bt, automotive, AC-DC and DC-DC power conversion, and its working principle is based on adjusting the voltage drop across its terminals.
