Product category:Thermistors
Material: Synthetic film
Quantity: 10PCS
Performance: General purpose
Temperature Coefficient: NTC
Working Temperature: -55~+200℃
Application Areas: Switching power supply, electronic energy-saving lamps, ballasts, etc.
High Quality: Thermistors are made of high-quality materials of synthetic films. Most NTC thermistors are oxide ceramics with spinel structure or other structures, with negative temperature coefficients. The resistance value can be approximately expressed as: Where RT and RTO are the resistance values at temperatures T and TO respectively, and Bn is the material constant. The resistivity of the ceramic grains themselves changes due to temperature changes, which is determined by the semiconductor characteristics.
Overview: This is a negative temperature coefficient thermistors whoseresistance changes with ambient temperature changes. Thermistors comprises 2or 4 kinds of metal oxides of iron, nickel, cobalt, manganese and copper, being shaped and Sintered at high temperature (1200℃ to 1500℃).
Features: Thermistors are radial lead resin coating type, with large material constant (B value), small residual resistance, thermal shock resistance, and wide operating temperature range. NTC thermistors are reliable and stable, with a wide overcurrent control range.
Small Size: This thermistors are small, powerful, fast, and have strong surge current suppression capabilities.Easy to store and carry.
Long Life: Thermistors have a long service life. High reliability, strong overload capacity, and easy to process into complex shapes.
High Sensitivity: Thermistors resistivity is more than 10~100 times greater than metal, and can detect temperature changes of 10-6℃.
Wide Temperature Range: Thermistors normal temperature devices are suitable for -55℃~315℃, high temperature devices are suitable for temperatures above 315℃, and low temperature devices are suitable for -273℃~-55℃.
Application: Suitable for power circuit protection of various electronic equipment such as conversion power supply, switching power supply, UPS power supply, various electric heaters, control motors, electronic energy-saving lamps, power lines, electronic ballasts, filament protection of lighting fixtures such as CRt and bulbs.
