The V18AUMLA2220H is a surface mount multilayer varistor (MLV) from Littelfuse's AUML series, designed for automotive transient voltage suppression. It offers a typical varistor voltage of 27.5V, with a minimum of 23V and maximum of 32V, and can absorb up to 25J of energy. The part is rated for a maximum DC voltage of 18V and maximum AC voltage of 14V, making it suitable for 12V automotive electrical systems.
This varistor is AEC-Q200 qualified for automotive applications and is listed as RoHS compliant. It is packaged in a 2220 (5750 Metric) surface mount package, allowing for compact board layouts. The operating temperature range is -55°C to 125°C, with storage temperature from -40°C to 150°C. The device features a temperature coefficient of clamping voltage less than 0.01 %/°C and a flammability rating of 94V-0.
Designed for load dump protection per SAE J1113, the AUML series provides robust protection against inductive energy discharges common in automotive environments. The leadless chip form eliminates lead inductance, ensuring fast response to transient surges. This varistor is bidirectional and requires no derating up to 125°C ambient.
