V250LA40A Description

Short technical summary and product information.

The Littelfuse V250LA40A is a metal oxide varistor (MOV) from the LA Varistor Series, designed for continuous operation across AC power lines for transient voltage surge suppression. It features a typical varistor voltage of 390V with a minimum of 351V and maximum of 429V, and can handle maximum continuous AC voltages of 250V and DC voltages of 330V.

 

This varistor offers a peak pulse current rating of 6.5kA (8/20µs waveform) and an energy absorption capability of 130J (10/1000µs single pulse). It has a nominal capacitance of 1000pF at 1MHz. The device is housed in a Disc 20mm package with through hole mounting and radial lead style, operating over an ambient temperature range of -55°C to 85°C.

 

The LA Series is UL recognized and certified by CSA, VDE, and CECC, making it suitable for a wide range of AC line voltage applications requiring robust surge protection.
