MOV-20D112K - Bourns

MOV-20D112K Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the MOV-20D112K?
  The recommended PCB layout for the MOV-20D112K involves placing the device as close as possible to the circuit being protected, with the shortest possible leads. The PCB should also have a solid ground plane to help dissipate heat and reduce electromagnetic interference (EMI).
• How does the MOV-20D112K respond to repetitive surges?
  The MOV-20D112K is designed to withstand repetitive surges, but its performance may degrade over time. The device can handle multiple surges up to its rated voltage, but the number of surges it can withstand before failing depends on various factors, including the surge voltage, current, and frequency.
• Can the MOV-20D112K be used in high-frequency applications?
  While the MOV-20D112K is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz. However, its performance may be affected by the high-frequency noise, and additional filtering may be required to ensure optimal performance.
• How does the MOV-20D112K affect the circuit's normal operating voltage?
  The MOV-20D112K has a negligible effect on the circuit's normal operating voltage. It has a very high impedance at normal operating voltages, which means it does not significantly affect the circuit's operation. However, it will clamp the voltage to its rated value during a surge event.
• Can the MOV-20D112K be used in parallel or series with other MOVs?
  Yes, the MOV-20D112K can be used in parallel or series with other MOVs to increase the overall surge protection capability. However, care must be taken to ensure that the MOVs are properly matched and that the overall circuit design takes into account the combined characteristics of the multiple MOVs.
