Inrush current limiters (ICL) are used to mitigate potentially damaging inrush currents in power supply units. As key components of power electronics, ICLs are designed to limit peak currents in circuits and prevent damage to the board caused by the initial high current flow. The application field and working principle of the B57213P0160M351 ICL will be explored in this article.

Application Field of the B57213P0160M351 Inrush Current Limiter

The B57213P0160M351 is a thermistor-based inrush current limiter (ICL) designed to limit the magnitude of surge currents to prevent the risk of damage or malfunction of connected devices.

This device utilizes a unique laminated thermal sensor to detect the temperature of the circuit and also has a low profile that allows for small footprints. This makes it well suited for use in applications such as LED lighting, communications equipment, automotive systems, consumer electronics, and general electronic solutions.

The B57213P0160M351 is also designed to have a high thermal, electrical, and mechanical stability. This makes it suitable for applications where extreme temperatures, shock, or voltage variations occur; ensuring reliable operation even under tough conditions.

Working Principle of the B57213P0160M351 Inrush Current Limiter

The B57213P0160M351 inrush current limiter works on a simple principle that utilizes a negative temperature coefficient (NTC) to detect variations in current and voltage. The thermistor element within the limiter has a certain resistance value that decreases when subjected to higher temperatures. This decrease in resistance of the thermistor reduces the current flow, limiting the magnitude of inrush current.

The thermistor element is designed to react to temperature changes rapidly as well as return to its original resistance value. This helps to ensure that the limiter is able to protect the device from damage due to overcurrent.

The B57213P0160M351 also utilizes a unique lamination process which enables it to have a low self-heating rate. This improves the device\'s ability to control inrush currents quickly and accurately without requiring a long waiting period.

Conclusion

The B57213P0160M351 Inrush Current Limiter is a thermistor-based device designed to limit the magnitude of surge current and protect circuitry from damage or malfunction. The device has a low profile, allowing for small footprints and is also durable and reliable, making it suitable for a wide range of applications. The working principle of the device is based on the principle of a negative temperature coefficient, allowing for rapid and accurate current limitation.
