Chassis Mount Resistors are some of the most commonly used devices in electronic circuits. The RER70F4R87RC02 is a particular type of chassis-mount resistor that is designed to offer excellent performance. This device has a rugged construction and is capable of operating in environments characterized by extreme temperature, shock, and vibration.
The RER70F4R87RC02 is an axial-through hole, three-terminal, radial-leaded resistor that has a resistance value range from 1.2kΩ to 2MΩ, with a maximum power rating. The body is constructed of ceramic to ensure that the device is small, lightweight and able to withstand temperatures ranging from -55°C to 125°C. Its construction is also designed to resist shock and vibration.
The primary application field for the RER70F4R87RC02 is signal filtering and signal conditioning. In signal filtering applications, this resistor is used to dampen unwanted or unpackaged signal components, eliminate harmonic signal noise, and reduce amplitudes of oscillations. It is also used in signal conditioning applications, such as tuners and amplifiers, to provide gain control, improve sound quality, and compensate for component tolerance.
The working principle of the RER70F4R87RC02 is simple yet very effective. When a signal passes through the resistor, the resistor dissipates some of the signal’s energy. This reduces the amplitude of the signal and thus attenuates the unwanted or unpackaged signal components. This process is known as signal filtering. The resistor can also be used to reduce the amount of noise due to its low-impedance characteristics, allowing for more quiet signal production.
Apart from its primary application field, the RER70F4R87RC02 can also be used in many other application areas such as current-regulation, transceiver signal protection, gate charge suppression, interference cancellation, EMI reduction, earphone protection, as well as ESD protection. This versatility makes it ideal for use in a wide variety of circuits.
The RER70F4R87RC02 is a highly reliable, cost effective, and versatile chassis-mount resistor that is suitable for a large number of applications. Its wide range of resistance values and temperature range, as well as its high power rating, make it an excellent choice for many electronic circuit designs.
