B57237S220M

The B57237S220M is a surface mount thermistor that is designed to measure and regulate temperature in electronic circuits and devices. Its primary function is to convert temperature changes into electrical resistance changes, which makes it an essential component in temperature sensing systems.

This thermistor has a resistance of 22 Ohms and a maximum power dissipation of 450mW at 25°C. It has a temperature coefficient of -4.5%/°C, which means that its resistance decreases as the temperature increases. This change in resistance allows it to be interfaced with other electronic components to provide accurate temperature measurement and control.

Furthermore, it is RoHS compliant, meaning it is free from harmful substances like lead and other toxic materials that can be dangerous to the environment and human health. 

The B57237S220M is a reliable and accurate temperature sensing component. It is designed to be soldered onto printed circuit boards (PCBs), making it easy to integrate into various electronic circuit designs. It is suitable for use in various electronic systems, including medical devices, telecommunications equipment, automotive electronics, and industrial control systems.

In summary, the B57237S220M thermistor provides accurate and reliable temperature measurement, which makes it a must-have component in electronic circuits and devices that require precise temperature sensing. It is a cost-effective and space-saving solution that is perfect for use with temperature-sensitive systems, and as it is RoHS compliant it's an ecofriendly option.
