Top Inrush Current Limiter Manufacturers in the World

In order to avoid gradual damage to an electronic component a tool has been used, which is known as inrush current limiter. NTC thermistors can be used as inrush-current limiting devices in power supply circuits when added in series with the circuit being protected. They present a higher resistance initially, which prevents large currents from flowing at turn-on. While focusing on the same, here we have mentioned the top inrush current limiter manufacturers in the world;


amethermAmetherm’s inrush current limiters are used to reduce the inrush current that occurs when an electrical device is switched on.

High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up. As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current. Additionally, devices that produce alternating current such as electric motors or transformers can draw several times their steady state current at switch on. Although this additional draw of inrush often lasts less than ½ of a normal 60 hertz cycle, that is enough time to cause possible damage to the equipment. The company has made its name in the top inrush current limiter manufacturers in the world.

AmphenolAmphenol’s thermometrics CL Series of Inrush Current Limiting Thermistors consists of a disc thermistor with uninsulated lead-wires, and are used to control inrush current when switching power supplies. The main purpose of limiting inrush current is to prevent components in series with the input to the DC/DC convertor from being damaged. Typically, inrush protection prevents nuisance blowing of fuses or breakers as well as welding of switch contacts. The company has made its name among the top inrush current limiter manufacturers in the world.

meanwellThe MEAN WELL ICL-16 is a 16A inrush current limiter that can be used to reduce the temporary peak current caused by capacitive loads, such as switch mode power supplies and LED drivers.

The ICL-28 is the 28A version of this device. Installing the inrush current limiter between the AC circuit breaker and the load can effectively reduce the possibility of the AC circuit breaker falsely tripping, when AC loads are started up, increasing the overall reliability of the system.  Meanwell has earned its name in the top inrush current limiter manufacturers in the world.

stThe STEVAL-SCR002V1 introduces a simple and innovative AC-DC front-end circuit that allows the designer to perform an inrush current limitation in any converter with input rectifier bridge topologies.

Based on a discrete control circuit made of one Z0110MN SMD triac and two STTH110A diodes, it offers a compact and non-insulated high voltage driver for the mains SCR. The drive circuit synchronizes the SCR gate signals with the AC line polarity and powers directly the SCR gate from the mains. This operation does not generate reverse losses in the SCRs. STMicroelectronics is one of the top inrush current limiter manufacturers in the world.
