Passive Component Test Solution

Besides testing capacitors, inductors and resistors individually, the passive components test devices are also able to measure assorted electronic components which are composed of them. The former includes wound components, communication and power filters; the latter includes switches, connectors, lead wires, conductive, dielectric material, magnetic material and semiconductor components. The tests not only analyze the characteristics of these components but also optimize the entire application process such as the inspection of auto manufacturing and incoming/outgoing material, quality verification and RD analysis to meet the low cost/high efficiency requirements.

Passive component wide-ranging application field in power electronic products :

• Ÿ Switch mode power supply(SMPS) : adapter, charger
• Ÿ LED power driver circuit
• Ÿ Photovoltaic(PV) : PV module, PV inverter
• Ÿ Electric vehicle(EV) : BEV, HEV, PHEV

Passive component test solution :

• Electrical characteristic measurement :
  Inductance, capacitance, resistance, impedance, dissipation factor, quality factor, leakage current, insulation resistance.
• Reliability(load life) test :
  Bias current test, power loss & core loss test, ripple current test, high frequency withstanding voltage test, high frequency withstanding current test, temperature rising test.
