MZ6 Series 06D75C1500R800V Ceramic Thermistor Type PTC Positive Temperature Coefficient Resistor, Suitable For Ballasts,
Good Stability And Strong Overload Capacity Ceramic PTC Thermistor
For LED Over-Current Protection
Thermistor is a sensitive component developed early, with many
types and mature development. Thermistors are composed of
semiconducting ceramic materials and utilize the principle that
temperature causes a change in resistance. When the temperature is
lower than Tc, the negative charge at the grain boundary is
partially offset by the polarization charge, so that the barrier
height is greatly reduced, and the grain boundary is in a
low-resistance state; when the temperature is higher than Tc, the
spontaneous polarization disappears, and the negative charge at the
grain boundary cannot It is obtained that the polarization charge
barrier is at a high level, and the grain boundary is in a
high-resistance state. The overall resistance of the material rises
sharply.
Application
The characteristics of PTC thermistor are:
1. Power saving
The energy input of the thermistor adopts the proportional type,
which has the current limiting characteristic of the protection
circuit, and saves power compared with the switching energy input
of heating elements such as nickel-chromium wires.
2. Long service life
The PTC thermistor itself is an oxide, there is no high-temperature
oxidation defect of the nickel-chromium element wire, and there is
no fragile situation of the infrared diode, the service life is
long, and the service life of the porous type is longer than that
of the non-porous type
3. It has the special performance of constant temperature,
adjustment and temperature control
When AC or DC voltage is given to the thermistor element to heat
up, below the Curie temperature, the resistivity is relatively low;
if it is higher than the Curie temperature, the resistivity
suddenly increases, so that the thermistor current is reduced to a
fixed value, reaching Automatic constant temperature, temperature
adjustment purpose
Competitive Advantage:
1, Convenient installment and small size
2, No requirement for reseting after over-heat protection
3, Quick action
4, We can offer equivalent PTC thermistor of Thinking & TDK
5, Long life working time
6, Good stability
7, Wide range protection temperature: 30~150°C
