Rising material costs and longer lead times are putting more pressure on both R&D and purchasing teams.
For MOV (Metal Oxide Varistor) selection, simply choosing the lower-cost option is not enough.
The key question is:
Can it deliver the required surge protection under your actual operating conditions?
Silver-electrode MOVs are well suited for demanding applications such as PV inverters, EV chargers and outdoor energy storage, where surge intensity and environmental conditions are more challenging.
Copper-electrode MOVs can be a cost-effective option for power adapters, smart home devices and indoor appliances, especially when BOM cost and supply stability are priorities.
The solution is not to replace silver with copper blindly, but to match the electrode, voltage rating, surge capability and application environment.
