Overvoltage Protection: Varistors with Increased Permissible Operating Temperature

TDK Corporation presents leaded EPCOS metal oxide disk varistors, which have now been approved for an increased operating temperature of 105 °C (previously 85 °C). The reason for this is the recertification of the B722* series of varistors in accordance with UL 1449, 4th Edition, and IEC 61051. Raising the permissible operating temperature to 105 °C also changes the climate category from...

ZVY Multilayer Varistors Offer High Temperature Operation

RALEIGH, NC – The ZVY Series of multilayer varistors is capable of operating temperatures of up to 150°C. Most multilayer varistors currently available are only able to operate up to 125°C. This higher temperature range makes the ZVY capable of voltage protection for low voltage electronics in a wider range of environments including industrial electronics and engine controls. Other...
