Product Overview
V120MLA1210NH is a Littelfuse MLA-series multilayer varistor for board-level transient suppression in a 1210 surface-mount package. It is the high-voltage 120 VDC member of the 1210 MLA range and is intended for protecting semiconductor and control circuitry from short-duration surge and ESD-related events.
The exact N/H ending identifies the nickel-barrier termination and reel packaging configuration. Electrically, the underlying V120MLA1210N grade is rated for 120 VDC or 107 VAC continuous operation.

Board-Level Protection Considerations
MLA parts are intended for transient events rather than continuous overvoltage absorption. PCB trace inductance between the protected node and the varistor should be kept low because long routing can add overshoot during fast transients.
