Micrograph at 2000x of a sintered ceramic, containing zinc oxide and bismuth oxide in a ratio of 50: Some la series model numbers are available with clamping voltage selections, designated by a model number suffix of either a or b. 130 vac to 465 vac
20N271K datasheet(1/5 Pages) HUAXINAN Metal Oxide
It is used to protect the circuit from high voltage spikes by varying its resistance.
The varistor is placed in a container holding 1.6 ±0.2 mm diameter metal balls such that only the terminations of the varistor are protruding.
The zinc oxide grains have been dissolved in an ammonium chloride solution, revealing the amorphous phase. There is no polarity for these leads and hence can be connected in both. You can determine this with a simple experiment. Use the varistor’s maximum load during a surge with the specifications on the datasheet.
Voltage range from 130v to 1000v, and an energy absorption capability up to 360j.
2 scanning electron micrograph (860x1. The metal oxide varistors offer a choice of varistor voltages from 18 v to 1800 v and vrms voltages from 11 v to 1100 v. For quantities of 500 and up, call for quote. The specified voltage shall be applied between both terminals of the specimen connected together and the electrode inserted between the metal balls.
(mm) device model number brand littelfuse metal oxide varistors za series *energy rating for impulse duration of 30ms minimum to one half of peak current (auto load dump).
The la varistor series are available in four model sizes: Metal oxide varistor huaan un datasheet est un document fourni par le constructeur du composant, où figurent toutes les données techniques sur le produit: Varistor voltage @ 1ma dc test current max. Ils sont en général fournis gratuitement, et se présentent très.
1 structure of metal oxide varistor.
Metal oxide varistor (mov) data sheet. Metal oxide varistors are similar to resistors and has only two leads. Once your experiment is complete, choose the metal oxide varistor that dissipates more energy that’s either equal or slightly higher than the required energy dissipation during a surge. Puissance dissipée, courant maximal, tension de seuil, tension de claquage, température de stockage, etc.
Metal oxide varistor (mov) data sheet.
Vdr metal oxide varistors standard links to additional resources ordering information the varistors are available in a number of packaging options: •bulk • on tape and reel • on tape in ammopack (fanfold) the basic ordering code for each option is given in tables titled varistors on tape on reel, varistors on tape in ammopack and. 7mm, 10mm, 14mm and 20mm; A metal oxide varistor (mov) is a protection component used in power supply circuits that is powered directly from ac mains.
