描述
Power NTC Thermistor has an excellent non-linearity characteristic for the resistance and temperature, its appliance is an easy and effective method to protect electronic device through surge current restrainning.

Feature of Power Thermistor
  • Power NTC thermistors are in small size but with a high power that to restrain the
    Surge current.
  • Power NTC thermistors  possess the electronic character of fast reflection, high reliability and long-life for use.
  • The material has a high constant as “B value” with small remained resistance.
  • Power NTC thermistors have a large application range integrate products  series.
Rage of Application
  • Switch mode power supply,  Adapter.
  • Transformer,  LED driver circuit.
  • Electronic rectifier,  electronic heater.
  • Electric  motor.
  • It has a protected function for RT , display, lighting device and circuit of different electronic equipment.
Certificates
  • Safety Approval Certificate: UL / CUL
  • Quality management system Certificates:  ISO9001:2008 
  • ISO14001:2004
Electrical Characteristics
  • Rated Zero-Power ResistanceRN (Ω) : 5±20% Ambient temp. Range:25℃±2℃(TA).
    Testing voltage: 1.5VDC
    After placing for 1~2 hours under TA, the resistance value shall be measured.
  • Thermal Dissipation Constant δ(mW/℃) : ≥15 , The thermal dissipation constant(δ) could be calculated by the ratio of a change in power dissipation(ΔP) of the thermistor to a change in temperature(ΔT) of the thermistor at a specified ambient temperature
  • Thermal Time Constant τ(s) : ≤68, The time(τ shall be measured within which the temperature change of NTC thermistor is reached at 63.2% of the ambient temperature change under zero power condition
  • Material Constant B : 2700±10% B=T1T2/( T2- T1) ×Ln (R1/R2), R1 , R2 is zero-power resistance at T1 , T2
    T1 = 298.15 K(25℃)  T2 = 323.15 K(50℃)
  • Max.Steady State Current (A) : visible mechanical damage.
    ΔRN / RN ≤20% (ΔR =∣RN-RN'∣), 25℃±2℃Ambient temp. Range, 5.0A  Testing Current
