Plug in NTC Thermal Resistor transient current suppression
thermistor 5D7
Generalization
Mf72 Power Type Ntc Thermistor Is a Semiconductor Ceramic Component
Made Of Transition Metal Oxides As The Main Raw Material. Category
Of Thermistors With Negative Temperature Coefficient. In Order To
Avoid The Surge Current Generated In The Boot Of The Moment In The
Electronic Circuit, a Power Type Ntc Thermistor In Series In The
Power Supply Circuit, Inrush Current Can Effectively Inhibit The
Boot, And After The Inhibition Of Surge Current, The Current
Through Its Continued Use Of Power Type Ntc Thermistor Resistance
Value Will Drop To a Very Small Extent, The Power It Consumes
Negligible Voltage Applied To Almost All The Equipment Behind So As
To Ensure The Normal Work Of The Circuit, So The Use Of Power Type
Ntc Thermistor In The Power Supply Circuit, Is The Most Simple And
Effective Suppression Measures For Surge Protection Of Electronic
Devices From Damage.
Application
It Is Suitable For The Protection Of Power Supply, Switching Power
Supply, Ups Power Supply, All Kinds Of Electric Heaters, Electronic
Ballasts, Power Supply Circuits Of Various Electronic Devices, And
Filament Protection Of All Kinds Of Picture Tubes, Displays,
Incandescent Lamps And Other Lighting Lamps.
Characteristic
1. Small Size, High Power, Strong Ability To Inhibit Surge Current.
2. Fast Reaction Speed.
3. Material Constant (b Value) Is Big, Residual Resistance Is
Small.
4. Long Life, High Reliability.
5. Series Full, Wide Working Range.
