390KD10 Description

Short technical summary and product information.

The Yageo 390KD10 is a metal oxide varistor (MOV) from the 10D series, designed for transient over-voltage protection in a wide range of electronic circuits. It features a typical varistor voltage of 39V (minimum 35V, maximum 43V) with a ±10% tolerance, and a maximum continuous AC voltage rating of 25V RMS and DC voltage rating of 31V.

 

This device can absorb surge energy up to 4.6J under a 10/1000µs pulse and handle a peak surge current of 1kA (8/20µs waveform). It has a typical capacitance of 2400pF at 1kHz, making it suitable for low-voltage power supply and signal line protection.

 

The 390KD10 comes in a disc 10mm through-hole package with 7.5mm lead spacing and 0.8mm lead diameter, enabling straightforward board assembly. It operates over a temperature range of -40°C to +105°C and is compliant with RoHS, Halogen Free, and MSL Level 1 requirements.
