07D361K is a common varistor, which belongs to voltage-sensitive electronic components. The code in its name has a specific meaning:

  • "07" indicates that the diameter of the component is 7mm
  • "D" represents the disc shape
  • "361" indicates that the nominal voltage is 360V
  • "K" indicates that the voltage tolerance is ±10%

Main Techanical Parameters

  • Varistor voltage (V1mA): 360V±10% (@1mA)
  • Maximum continuous operating voltage: 230V AC/300V DC
  • Maximum clamping voltage: 595V (at 10A)
  • Energy absorption capacity: 42J
  • Response time: <25ns
  • Operating temperature range: -40℃～+85℃
  • Capacitance value: about 140pF (at 1kHz)

Working Principle

The core material of the varistor is a sintered body of zinc oxide (ZnO) and other metal oxides. Under normal voltage, the potential barriers between ZnO grains prevent the current from passing; when the voltage exceeds the threshold, these barriers are broken down, forming a conductive channel, and the current increases rapidly. This characteristic makes it an ideal transient voltage suppression device.

Applications

  • Consumer electronics: mobile phone chargers, USB interface protection
  • Industrial control: PLC input/output protection
  • Communication equipment: Modem, router surge protection
  • Automotive electronics:Overvoltage protection
  • Household appliances: low-power power adapter

Summary

As a basic circuit protection component, varistors play an important role in various electronic devices. Correct selection and use of varistors can significantly improve the reliability and anti-interference ability of electronic products and reduce the failure rate caused by voltage transients.
