ROV10-331K-2 Application Field and Working PrincipleVaristors, also known as voltage-dependent resistors (VDRs), are essential for protecting electronic systems from voltage transients. The commonly used abbreviation for Varistors is MOVs. Radial Leaded Varistors, commonly abbreviated as ROV, are movs that come in a radial leaded package. ROV10-331K-2 is a radial leaded varistor designed to protect electronic systems from various transients, such as lightning, electrical and electro-magnetic.ROV10-331K-2 is designed for industrial-level protection in electronics and automotive applications, such as computers and related peripherals, communication equipment, consumer electronic products, industrial control equipment, and electrical and electronic appliances. The ROV10-331K-2 is constructed with a zinc oxide ceramic disc surrounded by a metal sheath, which consists of a lead-free, flame retardant encapsulation. The parameters are:•Varistor Voltage: 330V (typical)•Varistor Voltage: 331V (maximum)•Insulation Resistance >•Continuous voltage: 300VAC•Operating temperature range: -40°C to +85°C•Capacitance range: 1pF to 100nF•ESD Resistance: 100pF, 8kV (contact)The ROV10-331K-2 is mainly used in AC power line protection, automotive applications, and communication equipment. The varistor protects the connected circuit from overvoltage transients, thus preventing electrical and electronic components from becoming damaged. This protection is achieved by conducting electricity away from the connected components, thus passing the excess voltage harmlessly into the ground.The ROV10-331K-2 works according to the "varistor effect", which states that the electrical resistance of the varistor increases as the applied voltage decreases. In a nutshell, when a transient occurs, the voltage increases and the resistance of the varistor decreases allowing the current to flow. When the transient has passed, the voltage drops and the resistance of the varistor increases again, thus blocking the current flow and preventing further damage.In addition to its primary purpose of protecting against voltage and current transients, the ROV10-331K-2 also serves the following purposes:•To absorb and divert surges and spikes•To reduce audible noise in circuits•To extend the life of electrical components•To reduce electromagnetic interference•To reduce harmonic distortionFinally, the ROV10-331K-2 is a reliable and cost-effective solution for protecting electronic systems from various transients. It is also simple to install and easy to maintain, making it an ideal choice for industrial environment protection.The specific data is subject to PDF, and the above content is for reference
