Socay NTC MF72 Series MF72-SCN10D-9 Power Thermistor Suitable for Transformer/Adapter/Projector
DATASHEET: MF72-SCN10D-9_v2105.1.pdf
| Part Number | Resistance at 25℃ ±20% | Max. Permissible Working Current | Resistance under Load (mΩ) | Dissipation Factor | Thermal Time Constant | Maximum permissible capacitance @240Vac |
| R25(Ω) | Imax(A) | (mΩ) | δ(mW/℃) | τ(Sec.) | C(uF) | |
| MF72-SCN10D-9 | 10 | 2 | 458 | 11 | 32 | 110 |
Main Material
Connected in series on the circuit, at room temperature, NTC resistance value is large, in the moment the circuit is connected, can play a current limiting role; when the circuit works normally, NTC due to the temperature rise caused by passing current, at this time the resistance value drops, will not affect the normal operation of the circuit.

NTC Working Principle
Connected in series on the circuit, at room temperature, NTC resistance value is large, in the moment the circuit is connected, can play a current limiting role; when the circuit works normally, NTC due to the temperature rise caused by passing current, at this time the resistance value drops, will not affect the normal operation of the circuit.
