Product Description
Product Overview
CMF Chip NTC Thermistors are miniature, leadless devices designed for surface mount technology (SMT) applications. They offer superior solderability and resistance to soldering heat, making them ideal for both wave and reflow soldering processes. These thermistors are utilized for temperature compensation in various electronic components such as ICs, LCDs, transistors, and crystal oscillators in mobile communication equipment. They also serve as temperature sensors for rechargeable batteries and CPUs, and for temperature compensation in diverse circuit applications.
