Product Overview
The MF58 and MF51 series are precision glass-encapsulated NTC thermistors designed for accurate temperature compensation and detection. Manufactured using advanced ceramic, semiconductor, and glass encapsulation techniques, these thermistors offer high reliability, stability, and repeatability. They are suitable for a wide range of demanding applications, including household appliances, office equipment, industrial machinery, medical devices, and automotive electronics. The MF58 features tinned axial leads, while the MF51 utilizes bare radial copper leads, both encased in a robust glass shell for enhanced moisture resistance and durability in high-temperature environments. Their small size, light weight, and suitability for automatic insertion make them ideal for modern electronic designs.
