Temperature Measurement Radial Leaded Glass Encapsulated Bead MF51 NTC Thermistor
I Description Of The MF51 NTC Thermistor
Ampfort MF51 series of Glass Encapsulated thermistors are a special
breed of NTC thermistors. Hermetically sealed, these small
thermistors eliminate resistance reading errors caused by moisture
penetration and they function efficiently in extreme temperatures
as well as under severe environmental conditions.
This class of thermistor is free from limitations due to solder
temperature, which enables them to offer users a wide operating
temperature range of “-55 °C to +200 °C”. With diameters of only
1.5 mm, the devices’ small size allows for encapsulation in a
variety of housings, such as ring lugs and hex nuts.Radial leaded
glass encapsulated thermistors provide a low cost option for
applications that require superior stability and high temperature
operation. The thermistors are glass encapsulated to allow for
operation in a wide array of environments including high humidity
and rapid thermal cycling. The small size allows the sensor to
react quickly to small temperature changes.
II Features Of The MF51 NTC Thermistor
■ Glass-sealed bead provides High-level heat resistance and high
environmental Stability
■ Proven long term Reliability with low power requirement
■ Smaller size , High Sensitivity and Faster thermal response than
conventional thermistors
■ Operation from -50˚C up to 300˚C
■ Values from 2186Ω to 1.38MΩ at 25˚C
■ Standard tolerance of ±3% at rated temp
■ Temperature measurement and control
■ High temperature stability
■ Glass encapsulation provides resistance to moisture and other environmental factors
■ Available in ceramic reinforced glass body or glass bead configurations
III Applications Of The MF51 NTC Thermistor
■ Automotive (water, intake air, ambient, battery, motor and fuel)
, hybrid vehicles, fuel cell vehicles, automotive electronics
■ Assembly into various probes of Temperature sensors
■ General Instrumentation applications
■ Temperature measurement and control commonly used in HVAC
applications, water heaters, microwave ovens, home appliances
■ Temperature control in common household appliances such as coffee
makers, ovens, and refrigerator’s.
■ Industrial applications may include monitoring battery pack
terminal temperature while in a charge state.
■ Medical applications that rely on airflow such as respirators.
■ Outdoor applications such as infrared lighting systems.
