The CMF Chip NTC Thermistors are miniature, leadless components 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 widely used for temperature compensation and sensing in various electronic devices, including mobile communication equipment, rechargeable batteries, and CPUs.
