Metal Oxide Varistor | KOA Speer

The NV73 series varistors protect electronic components against static electricity as well as switching and incoming surges, making them ideal for a variety of electronic equipment applications. KOA Speer NV73 varistors feature a large withstanding surge capability and symmetrical V-1 characteristics that make surge absorption possible in either direction.  The NV73 series metal oxide varistors are available in sizes 0201, 0402, 0603, 0805, 1206, 1812 and 2220. Varistor voltage range from 8 ~ 150, with a max allowable voltage a.c. rms (V) of 4.2V ~ 95V and a maximum peak current (@ 8/20ms) of 0.5A ~ 1200A depending on the size and style of selected component.


The NV73DL metal oxide varistor, for operating up to +125°C high temperature applications, offers a high max energy (J) of 0.1 ~ 1.5, maximum peak current (@8/20ms) of 80A ~ 300A and a varistor range of 12 ~ 82.
