En varistor är en elektrisk komponent, en typ av elektriskt resistor. Namnet är en kortform för varierande resistor. Ett annat namn är VDR, vilket är en förkortning . A varistor is an electronic component with an electrical resistance that varies with the applied voltage.

Electronics Tutorial about the Varistor and Metal Oxide Varistor or MOV which is used in power electronics circuits for protection against transients. En linje filter är ett elektroniskt filter som används för att dämpa eller minska oönskade signaler .

Varistors provide reliable and economical protection against high voltage transients and surges which may be produce. To find the varistor that meets your needs, start with Littelfuse. Metal-oxide varistors (MOVs) are relatively simple devices, choosing the right one requires some knowledge. Glosbe, online-lexikon, gratis. Bläddra milions ord och fraser på alla språk.

Varistors are electronic components for which the resistivity changes with the applied voltage. With industry-leading research and design tools, Arrow makes finding the right part easy. TVS diodes are not the only option.

Varistors are in stock and ship same-day at Mouser Electronics from industry leading manufacturers. Mouser is an authorized distributor for many varistor. Product information and news of Chip Varistor , Panasonic. ZNR stands for Zinc–oxide Non-linear Resistor – also known as Varistor or MOV.

Shop with confidence on eBay! Circuit Protection – TVS – Varistors , MOVs are in stock at DigiKey. The magnitude of the overshoot varies from device to device and depends on the varistor formulation. VARISTOR MICROSTRUCTURE AND FABRICATION . Voltage protection devices from EPCOS include Varistors , CeraDiodes, CTVS, Ceramic Transient Voltage Suppressors, Multilayer and SMD Varistors for . Products includes NTC, varistor (also known as MOV, metal oxide varistor , VDR), chip varistor (so-called MLV), PTC, PPTC (so-called resettable fuse) . Can be used with both DC and AC circuits. In the varistor according to the present invention, the varistor element body has the high-resistance region formed by diffusing the alkali metal in the . The MOV-14DxxxK Series of mm radial leaded varistor devices protects against overvoltage transients such as lightning, power contact and power induction.

Special varistor voltage range. If customers have no special request on lead shape, we provide straight lead for voltage type ≤ 471K and in-line crimped. Define varistor : an electrical resistor whose resistance depends on the applied voltage.
