Mov 14D471k varistor
Description
The 14D471K is a common Metal Oxide Varistor (MOV) used for surge protection in electronic circuits. It acts as a voltage-dependent resistor, rapidly dropping its resistance when a high-voltage spike occurs to shunt the excess energy away from sensitive components. Function: Designed to protect sensitive electronic equipment by shunting excess voltage surges. Technology: Made from semiconductor ceramic materials, typically zinc oxide, which have a non-linear, voltage-dependent resistance. Applications: Used in power supplies, surge protectors, inverters, and grid-tie equipment. Characteristics: These components generally have a high voltage rating, often operating up to 1000V or higher depending on the specific model.
Element Diameter 14 mm Varistor Voltage 470V (Typical) Voltage Range (V_{1mA}) 423V to 517V Maximum AC Voltage 300V RMS Maximum DC Voltage 385V Clamping Voltage 775V (at 50A) Max Surge Current 4500A (8/20\mu s pulse) Tolerance \pm 10\% (indicated by 'K')
Key Applications Power Supplies: Protecting AC input stages from mains transients. Industrial Equipment: Shielding relays and contactors from inductive kickback. Consumer Electronics: Common in surge protectors and power strips. Solar Inverters: Often used in the AC or DC protection stages to prevent damage from lightning-induced surges.
