RER40F4870RCSL, to classify, is a high precision, 0.25 W rated surface mount resistor with closed loop design. It features adjustable resistance between 0.5 - 2.7 kΩ and a tolerance of ±10%. It is available in a single-in-line package and is compliant with IoP standards.

Application Field

The RER40F4870RCSL is suitable for a wide range of applications, including temperature control, current limitation, voltage regulation and gain-setting on amplifiers. It is often used in the automotive, medical electronics, instrumentation and consumer electronics markets, providing a stable performance in high-temperature environments. The low-power design makes them suitable for use in circuits with limited power. The RER40F4870RCSL is especially popular with designers that require precision and stability with minimal space.

Working Principle

The RER40F4870RCSL utilizes a cermet resistive element combined with a mechanical rotary switch to adjust the resistance output. Cermet is a combination of ceramic and metals that is both corrosion resistant and temperature stable. It is shaped as a disc surrounded by a metal shell. A spring is fitted to the disc in order to form the electrical connection when activated by the rotary switch. When adjusted, the spring provides variable contact with the resistive element, resulting in an adjustable resistance between 0.5 - 2.7 kΩ.

Conclusion

The RER40F4870RCSL is a low-power, high-precision, chassis mount trimming resistor that provides reliability and accuracy in a variety of applications. It is ideal for use in temperature control, current limitation, voltage regulation and gain-setting on amplifiers. It is also highly compatible with IoP standards and has proven its durability in high-temperature environments. As a result it is an excellent choice for those who require precision and stability in minimal space.
