MF58 MF51 PRECISION GLASS ENCAPSULATED NTC THERMISTORS (MF58 & MF51) MF58 Glass Shell Precision NTC Thermistors The MF58 is a NTC thermistor which is manufactured using a combination of ceramic and semiconductor techniques. It is equipped with tinned axial leads and then wrapped with purified glass. Applications Dimensions (mm) Temperature compensation and detection for: • Household appliances (air conditioners, micrwave ovens, electric fans, electric heaters etc.) • Office equipment (copiers, printers etc.) • Industrial, medical, environmental, weather and food processing equipment • Liquid level detection and flow rate measurement • Mobile phone battery • Apparatus coils, integrated circuits, quartz crystal oscillators and thermocouples. Features • Good stability and repeatability • High reliability • Wide range of resistance: 0.1~1000KΩ • Tight tolerance on resistance and Beta values • Usable in high-temperature and high-moisture environments • Small, light, strong package, • Suitable for automatic insertion on thru-hole PCBs • Rapid response • High sensitivity Specifications Main Techno-Parameter • Zero power resistance range (R25): 0.1~1000KΩ • Available tolerances of R25: F=±1% G=±2% H=±3% J=±5% K=±10% • B value (B25/50°C) range: 3100~4500K • Available tolerances of B value: ±0.5%, ±1%, ±2% • Dissipation factor: ≥2mW/°C (In Still Air) • Thermal time constant: ≤20S (In Still Air) • Operating temperature range: -55°C ~ +200°C • Rated Power: ≤50mW MF51-B Precision Glass Encapsulated NTC Thermistor for Temperature Measurement The MF51 NTC thermistor is a small chip thermistor encased in glass with bare radial copper leads. The chip is made from a new material using new techniques which provide benefits such as high precision, fast response, reliable stability, no aging effect and improved moisture resistance. Applications Dimensions (mm) It can be used in applications such as refrigeration, HVAC, heating equipment, electronic thermostats, liquid level sensing, automotive electronics, electronic dashboards, etc. Specifications The fourth pane shows the Beta value (B25/50C) The third pane shows the tolerance code of rated resistance.
