Chassis Mount Resistors
Chassis mount resistors, also known as box, body, or panel mount resistors, are components that are meant to be mounted onto a chassis while dissipating power in an electronic circuit. This type of resistor is commonly used in circuits where power must be transferred through a high current channel, and where the overall size and weight of the device must be minimized. The RER50F7R87RCSL is one such chassis mount resistor which is available in both surface mount (SMD) and through hole (TH) versions.
The RER50F7R87RCSL is a thick film resistor with a maximum power rating of 7 Watts. These resistors are known for having high temperature coefficients, making them ideal for applications where there is a large temperature range. It has a large resistance range (5 to 10 mΩ) making it suitable for various applications. It is also highly resistant to the effects of humidity and other environmental factors. The RER50F7R87RCSL is available in a range of both standard and custom packaging, making it a ideal for a wide array of applications.
The RER50F7R87RCSL provides an alternative approach for reliably transferring power that is often used in applications where standard resistor designs are unsuitable. The device\'s design involves two ceramic plates that are separated by a layer of sputtered silicone material. This design creates a low-resistance, high contact area contact pad. This contact pad ensures efficient thermal transfer, making it a reliable solution for a wide range of applications.
The RER50F7R87RCSL is commonly used in different types of motor control applications, such as fan motors, tilt-motors, and other applications. This device provides efficient heat transfer for high currents and is designed to resist heat and moisture efficiently. It is also well-suited for applications where electrical and thermal management is a major concern. The RER50F7R87RCSL has a temperature coefficient of up to 500 ppm/°C making it suitable for long-term use in temperature-sensitive applications.
The working principle of the RER50F7R87RCSL is based on the use of two ceramic plates. The contacts are connected to each other using a sputtered silicone material which is designed to maintain a low-resistance, high contact area contact pad. The contact pad effectively dissipates the heat of the power dissipated in the circuit. Heat is then removed from the device by an attached heat sink, and then dissipated into the chassis.
In conclusion, the RER50F7R87RCSL is a reliable chassis mount resistor that can be used for various applications such as motor control and thermal management. This device offers a low-resistance, high contact area contact pad which provides efficient thermal transfer. It is also resistant to temperature and humidity, making it suitable for long-term use in temperature-sensitive applications.
