Overview

The 103JL1A is a 10k ohm NTC thermistor housed in a hermetically sealed DO-35 glass package. Designed for high-reliability temperature sensing, it operates across an exceptionally wide range from -55 degC to +300 degC. This axial-leaded component offers excellent long-term stability and high voltage insulation for demanding environments.

Why Choose This Part

The hermetically sealed glass package ensures superior resistance to moisture and environmental contaminants compared to epoxy-coated alternatives. Its wide operating temperature range up to 300 degC makes it suitable for extreme thermal applications, while the axial lead format allows for flexible mounting via soldering or welding.

Applications

Industrial High-Temperature Ovens
Monitoring and controlling thermal profiles in industrial processing equipment reaching up to 300 degC.
HVAC Temperature Sensing
Providing accurate air or fluid temperature feedback in heating and cooling systems.
Automotive Under-Hood Sensing
Measuring engine oil or coolant temperatures where hermetic sealing protects against harsh fluids.
Home Appliances
Thermal protection and temperature control in coffee makers, toasters, and small kitchen electronics.
