Frequently Asked Questions:

Q: Is this MOV polarity sensitive?
A: No, Metal Oxide Varistors (MOVs) are bilateral devices and are not polarity sensitive.

Q: Can this varistor be used in AC circuits despite the DC voltage rating?
A: Yes, due to its bilateral and symmetrical V-I characteristics, this MOV can be used in AC circuits for transient overvoltage protection.

Q: What is the significance of the 8/20µs waveform for peak surge current?
A: The 8/20µs waveform is a standard industry test pulse used to characterize a varistor's ability to withstand a specific surge current magnitude and duration.

Q: What is the recommended mounting orientation for this 20mm disc varistor?
A: The 20mm disc varistor can be mounted in any orientation, provided there is adequate clearance and heat dissipation.
