Metal Oxide Varistors - 10D Series
Features
1. Wide operating voltage (V1mA) range from 8V to 1800V.
2. Fast responding to transient over-voltage.
3. Large absorbing transient energy capability.
4. Low clamping ratio and no following-on current.
General Information
The MOV-10DxxxK Series of 10 mm radial leaded varistor devices protects against overvoltage transients such as lightning,
power contact and power induction. The metal oxide varistors offer a choice of varistor voltages from 18 V to 1800 V and Vrms
voltages from 11 V to 1000 V. The devices have a high current handling, high energy absorption capability and fast response
times to protect against transient faults up to rated limits.
General Characteristics
No Radioactive Material Storage Temperature: -55ºC to +125ºC
Operating Temperature: -55ºC to +85ºC
Body: Nickel Plated
Leads: Surface-mount, Axial Devices: Tin Plated
Devices with No Leads: Nickel Plated

Metal Oxide Varistors - 10D Series
Current Energy and Power Dissipation Ratings
Should transients occur in rapid succession, the average power dissipation is the energy (watt-seconds) per pulse times
the number of pulses per second. The power so developed must be within the specifications shown on the Device Ratings
and Specifications Table for the specific device. The operating values of a MOV need to be derated at high temperatures as
shown above. Because varistors only dissipate a relatively small amount of average power they are not suitable for repetitive
applications that involve substantial amounts of average power dissipation.
