A June 30, 2003 Tyco Electronics Corporation 308 Constitution Drive, Menlo Park, CA 94025 Tel: (800) 227-4856 Fax: (800) 227-4866 1 of 10 GENERAL DESCRIPTION The ROV07-XXX (Radial-leaded Metal Oxide Varistor) products are 7mm radial leaded varistor devices suitable for protection of overvoltage transients. ROV devices can provide protection for a wide variety of power systems against overvoltage faults such as lightning, power contact and power induction. Suitable for a broad range of applications including, but not limited to security, power supplies, surge strips, etc., the ROV device helps to protect valuable equipment from potential power surge damage by clamping high energy, short duration impulses. The ROV devices have high current handling and energy absorption capability and fast response times to help protect against transient faults. FEATURES ? Radial leaded ? Broad Varistor voltage and Vrms range Varistor voltage : 18V - 820V Vrms voltage : 11V - 510V ? Two surge capability series Standard series, High surge series ?
