Een spanningsafhankelijke weerstand (Engels: Voltage Dependent Resistor, afgekort VDR, ook varistor ) is een weerstand waarvan de waarde varieert met de. 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. To find the varistor that meets your needs, start with Littelfuse.
Terminology Used in Varistor.
Read more about metal oxide . Varistors are electronic components for which the resistivity changes with the applied voltage. TVS diodes are not the only option. They have the capability to absorb high transient . Varistors provide reliable and economical protection against high voltage transients and surges which may be produce. Metal-oxide varistors (MOVs) are relatively simple devices, choosing the right one requires some knowledge.
With industry-leading research and design tools, Arrow makes finding the right part easy.
Varistors are in stock and ship same-day at Mouser Electronics from industry leading manufacturers. Mouser is an authorized distributor for many varistor. Shop with confidence on eBay! TDK-EPC offers reliable and cost-effective solutions for this purpose: thermally protected varistors and gas-filled surge arresters from EPCOS.
ZNR stands for Zinc–oxide Non-linear Resistor – also known as Varistor or MOV. The MOV-14DxxxK Series of mm radial leaded varistor devices protects against overvoltage transients such as lightning, power contact and power induction. The magnitude of the overshoot varies from device to device and depends on the varistor formulation. VARISTOR MICROSTRUCTURE AND FABRICATION . 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.
Can be used with both DC and AC circuits. Silicon diodes and metal-oxide Varistors are used to protect delicate circuit components from electrostatic discharge (ESD) or other transient events. All the details on our product families in the Wurth Electronics catalog Passive Components.
