Product Overview
Function: Negative Temperature Coefficient (NTC) Resistor, whose resistance
changes with ambient temperature changes. Thermistors are comprised
of 2 or 4 kinds of metal oxides (iron, nickel, cobalt, manganese,
and copper), shaped, and sintered at high temperatures (1200 to
1500).
Advantages: Small size, large power, strong capacity of inrush current
suppression, fast response, large material constant (B value),
small residual resistance, long life, high reliability, complete
series, and wide applications.
Applications: Switching power supplies, switch power, UPS power, electronic
energy-saving lamps, electronic ballasts, all kinds of electric
heaters, all kinds of RT, displays, bulbs, and other lighting
lamps.

Notes and Precautions
Storage Place: Do not expose the components to corrosive gas, deoxidizing gas,
flammable and explosive gases, oil, water, chemical liquid, or
direct sunlight, as this may result in deterioration of
characteristics.
Usage Precautions: Do not apply the components under conditions exceeding Imax,
exceeding the rated temperature range, or with inferior thermal
dissipation, as this may result in deterioration of
characteristics, component destruction, or in the worst case, fire.
