New NTC Thermistor with Flexible Leads and Faster Thermal Response

108

Overview

Murata has improved its NXF series of thermal string type NTC thermistors with flexible leads, and commercialized it as a new type (NXF*15******E*****).

This product is intended for use in applications such as automotive onboard equipment and consumer equipment. Production is scheduled to commence in September 2017.

Background

The NXF series of thermal string type NTC thermistors with flexible leads is a series of electronic components for detecting and measuring temperature. These sensors feature one of the industry’s smallest sensor heads, realizing compact size and fast thermal response.
The new type (NXF*15******E*****) thermistor has 25% faster thermal response (compared to the hot constant of the previous model), which has been realized by selecting an appropriate wire material and internal construction. It is thus optimum for detecting the temperature at a point separate from the PC board, and also as a temperature sensor for assemblies.
