ERZ-V20D471 metal oxide varistor with 10kA surge rating

ERZ-V20D471 is a Panasonic ZNR series metal oxide varistor (MOV) built as a single-circuit, through-hole disc device with a 21.5 mm disc size. Maximum continuous ratings are 300 VAC and 385 VDC. Varistor voltage is 470 V typical, with a stated range of 423 V minimum to 517 V maximum. Surge current rating is 10 kA, and energy rating is 350 J. Capacitance is 900 pF at 1 kHz. Clamping voltage is specified at 775 V maximum. Mechanical attributes include straight leads with 10.0 mm lead spacing and 1.0 mm lead diameter, supporting stable radial mounting in power-entry and surge paths. ERZ-V20D471 is used where repeatable MOV behavior and defined surge handling are required. Request a quote for ERZ-V20D471.
