The MF58 glass-encapsulated NTC thermistor utilizes glass encapsulation technology and is designed for temperature monitoring in harsh environments. Its nominal resistance ranges from 0.1Ω to 3780kΩ, with a B value range of 3100K to 4500K, and it offers ultra-high accuracy of ±0.5%. Its operating temperature range extends from -55°C to +250°C.
Key specifications include a 50mW rated power, a dissipation factor of ≥2.0mW/°C, and a thermal time constant of ≤20 seconds, ensuring measurement stability over the entire temperature range. The cylindrical glass envelope, with a diameter of 4mm and a length of 27mm, ensures fast thermal response and mechanical strength. Tinned copper leads support automated assembly.
With resistance tolerances as low as ±1% and B value tolerances of ±0.5%, this series meets the needs of high-precision temperature compensation. This series is suitable for household appliance temperature control systems, industrial equipment overheat protection, mobile phone battery thermal management, and instrument circuit compensation.
Typical applications include air conditioning compressors, microwave oven sensors, printer fuser units and automotive electronic modules. Glass encapsulation ensures long-term reliability in high temperature and high humidity environments.
