## Overview

The RC Snubber/Absorption Circuit Module is a 5-piece set designed to protect relay contacts and thyristors from voltage spikes and electromagnetic interference in inductive loads ranging from 5 to 400 volts. Featuring a varistor for surge suppression and a resistor-capacitor network to absorb harmful electromotive forces, it ensures longer device lifespan and stable microcontroller operation. Its crimp terminal design allows for quick, hassle-free installation, making it an essential upgrade for professional-grade electronic switching circuits.

## Description

Module features: RC absorption circuit is also called RC buffer circuit. It is a circuit structure in which resistors and capacitors are connected in series and connected in parallel with switching devices. It is used to improve the voltage and current waveforms that electronic power devices endure when they are turned on and off. The RC absorption loop module can prevent the induced electromotive force generated at the moment when the inductive load is turned on and off from causing damage to switching devices such as relays and thyristors, prevent electromagnetic interference and increase the anti-interference ability of the microcontroller. Application: This module is suitable for circuits containing inductive loads and switching devices (such as relays and thyristors). When used, the two interfaces of the module are on the two contacts of the relay (such as the common end and the normally open end of the relay), or in parallel with the thyristor. , to avoid damage to relays and thyristors caused by induced electromotive force. Package includes: 5pcs RC Snubber/Absorption Circuit Module

Review: Simple to use - Easy to use and cuts down switch and relay contact arcing
Review: This is a useful snubber with good build. The only point is that the varistor type is 10D471K (10mm disk, with 470V +/-10% clamping voltage, 45-67mJ dissipation). This rating is typically used for 220/240VAC lines. For the North American market a 10D271K varistor is the better choice to effectively absorb transient energy for equipment operating at 110/120VAC voltage. The RC snubber is composed of a 220 Ohms/1Watt carbon resistor paired with a 100nF/630V film capacitor.

## Features

- Applicable Load: Suitable for AC or DC 5-400V inductive load (load less than 1000W) to protect relay contacts or thyristors.
- Prevention: Equipped with a varistor to prevent voltage fluctuations and excessive current, ensuring the relay's durability and preventing contact adhesion.
- Function: The RC absorption circuit module effectively safeguards relays and thyristors by preventing damage caused by inductive electromotive force during power on/off. It also enhances the microcontroller's anti-jamming capability and prevents electromagnetic interference.
- Efficient Absorption: Absorbs induced electromotive force generated by inductive loads, ensuring smooth operation and preventing damage.
- Convenient Design: Enjoy the convenience of crimp terminals, making wiring quick and hassle-free, saving you time and effort.
- Application: This module is suitable for circuits containing inductive loads and switching devices (such as relays and thyristors).
- Package includes: Includes 5pcs RC Snubber/Absorption Circuit Module, offering great value for money.
