Product Overview
The CMF Chip NTC Thermistors are miniature, no-lead surface mount devices designed for temperature compensation and sensing applications. Ideal for high-density SMT installations, these thermistors offer superior solderability and resistance to soldering heat, making them suitable for both wave and reflow soldering processes. They are commonly used in mobile communication equipment for temperature compensation of ICs, LCDs, transistors, and crystal oscillators, as well as for temperature sensing in rechargeable batteries and CPUs.
