AI Summary

ZV50K1812401NIR1HT by Bourns Inc.: 82 V 400 A Varistor 1 Circuit Surface Mount, MLCV 1812 (4532 Metric).

The Kyocera AVX VG series features glass encapsulation to protect the varistor ceramic body from moisture and harsh chemical environments, making it highly robust. It matches the primary electrical limits while trading off peak temperature rating.

  • Glass encapsulated design provides superior protection against harsh environments
  • AEC-Q200 Qualified for high reliability requirements
  • Matches 50 V AC, 65 V DC, and 82 V electrical ratings
  • Lower maximum operating temperature limit (+125°C vs +150°C)
  • Slightly lower maximum energy handling (4.5 J vs 4.8 J)

This is the standard-temperature sibling from the same Bourns ZV series, matching all electrical parameters except for the premium high-temperature capability. It acts as an immediate drop-in replacement if the application's operating ambient temperature does not exceed +125°C.

  • Direct sibling part from Bourns in the same series
  • Identical electrical specs: 50 V AC, 65 V DC, 82 V typ varistor voltage
  • Identical surge capability: 400 A peak current and 4.8 J energy absorption
  • Lower maximum operating temperature limit (+125°C vs +150°C)

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
