Littelfuse, Inc. Varistors, MOVs V56MLA1206T

The Littelfuse MLA Series Varistor, part number 05B9354, is a surface mount multilayer varistor designed for transient voltage surge suppression. It operates within a voltage range of 3.5V to 120V and is rated for a maximum clamping voltage of 120V at a surge current of 100A (8/20¬µs waveform). The device features a capacitance of 180pF at 1MHz and is suitable for applications requiring electromagnetic compliance, particularly for protecting integrated circuits and other components at the circuit board level. This varistor is RoHS compliant and can operate in ambient temperatures ranging from -55¬8C to +125¬8C. Its leadless design allows compatibility with modern reflow and wave soldering processes, making it a compact alternative to traditional plastic-housed components. The MLA Series is particularly effective in suppressing inductive switching and other transient events, including those specified in IEC 61000-4-2 for ESD protection.
