Product Description
Product Overview
The TE Connectivity GA2.2K3A1 Series I thermistors are small, epoxy-coated devices featuring solid tin-plated lead wires. Designed for precision temperature measurements, indication, control, and thermal compensation, these thermistors offer interchangeability, proven stability, reliability, and rapid time response. The series utilizes alloy lead wires for reduced thermal conductivity and a thermally conductive epoxy coating. They are RoHS compliant and suitable for a wide range of applications including temperature sensing, control, compensation, and tight tolerance instrumentation.
