Capacitors
Find capacitors with the right voltage and capacitance from capacitor manufacturers, suppliers and distributors
Power capacitors go back to 1745 when E. G. von Kleist invented the Leyden jar; however, some credit Pieter van Musschenbroek with a similar device that same year. Today’s industry, far removed in time, reflects an accelerated pace for the capacitor due to technological advancements spurred by consumer demands for electrical devices. This isn’t about a flux capacitor, used for time travel in "Back to the Future," but down to earth components that store energy typically between two plates.Capacitors, once popularly known as condensers, find applications in most electrical devices. Common types include the electrolytic for timing circuits, tantalum that offers good characteristics for frequency and temperature and metalized polyester considered a multi-application capacitor. When buying electronic capacitors consider the following:
1. Decide on pre-manufactured capacitors or specially designed units with up-front production costs offered by manufacturers.
2. Deal with suppliers and distributors that offer discounts or wholesalers with limited types of capacitors.
3. When looking for high voltage capacitors choose from companies that specialize in these heavy-duty products offering a mix of voltage and capacitance ranges.
Work with capacitor manufacturers for business specific results
These manufacturers provide solutions for switching power supplies, numerous voltage environments and other industrial needs. Choose by application, such as input filters, snubbers, DC buss, AC voltage, pulse discharge and surge protection.

- A common misnomer for the abbreviation "NPO" defines the letters as non-polarized. This abbreviation stands for "Negative-Positive-Zero." A capacitor with a black top indicates the NPO value that typically ranges 1.8pF to 120pF. This black top qualifies that under any temperature, the capacitance stays constant.
