Low Voltage SMD 1812 Multilayer Chip Metal Oxide Varistors MVR1812-390H 39V 800A 2500pF 3.1J 4532 Metric Surface Mount


Description


The MVR Series of low voltage varistors is designed to protect sensitive electronics devices against high voltage surges in the low voltage region. They offer excellent transient energy absorption due to improved energy volume distribution and power dissipation. Low voltage varistors cover wide DC operating voltage range from 3V to 170V. The MVR Series is the same except for higher operating temperatures up to 150ºC. MVR varistors are typically applied to protect components at the circuit board level.



Features


* Sizes available: 0603, 0805, 1206, 1210, 1812, and 2220

* Nickel barrier terminations

* AC operating voltage range from 2 VRMS to 130 VRMS

* DC operating voltage range from 3 VDC to 170 VDC

* No plastic coating for a better flammability rating

* Inherently bi-directional

* Operating temperature range from -55°C to +125°C

* Compliant with AEC-Q200 (Grade 1)


Application


• On-board protection of voltage sensitive IC’s and transistors

• Fire and carbon monoxide detection

• Sensors and monitoring equipment

• Timers

• Auto and heavy equipment instrumentation

• ESD protection for components sensitive to IEC 1000-4-2, MIL-STD 883C Method 3015.7 and other industry specifications

• Suppression of inductive switching or other low to medium transient events at the circuit board level • Provides on-board transient voltage protection of ICs and transistors

• Replace larger surface mount TVS Zeners in many applications

• Used to help achieve electromagnetic compliance of end products

• 6 model sizes available 0603, 0805, 1206, 1210, 1812 and 2220
