Product Overview

The Analog Technologies ATH5K1R8B3950K is an ultra-stable, axial-leaded thermistor designed for precise temperature sensing and control across a wide temperature range of -55C to 250C. Featuring glass encapsulation for long-term stability and reliability, this thermistor offers a high resistance accuracy of 1% and a quick response time of 20s. Its compact size (1.8mm x 3.7mm) and tin-plated copper-clad steel leads make it suitable for demanding applications in automotive electronics, industrial electronics, and home appliances where cost-sensitive and reliable temperature measurement is crucial. It is also widely used in temperature compensation, control systems, power electronics for thermal protection, battery management systems, and consumer electronics.
