EPCOS B57703M Temperature Measurement NTC Thermistors

EPCOS B57703M Series Temperature Measurement NTC Thermistors are a unique kind of variable resistive element that alters its physical resistance in response to temperature variations. The B57703M Temperature Measurement Thermistors’ relatively large negative response of an NTC thermistor means that even small changes in temperature can cause significant changes in their electrical resistance. These B57703M NTC Thermistors are highly accurate, easily mountable, and offer good thermal coupling through a metal tag. EPCOS B57703M Temperature Measurement NTC Thermistors feature an operating temperature range from -55°C to +300°C and a power rating of 150mW. Typically, B57703M NTC Thermistors are used in cooking appliances, commercial refrigeration, surface temperature measurements, and electric ranges.

Video Transcript

Some electronics enjoy the heat, while others feel the heat and become unable to function. So, measuring temperature is an essential component of your design, whether you're trying to cool something down or heat something up. EPCOS series S861 and M703 NTC Thermistors offer precise temperature readings in a variety of applications.

The S861 series are AEC-Q200-qualified sensors with a miniature epoxy-encapsulated thermistor. They provide a short response time with tight tolerance down to 1%. The M703 series encapsulates the thermistor in an eyelet tab that provides simple mounting and precise thermal coupling. These NTC Thermistors are UL-listed components that come in a variety of resistance values and arty characteristics. The leads are PTFE insulated with silver plating over copper or nickel wire. These components are the answer to your design and regulatory needs.
