Vishay Intertechnology has pioneered a new series of miniature snap-in power aluminum electrolytic capacitors. The capacitors are ideal for power supplies, solar inverters, and industrial motor controls. The Vishay BCcomponents 259 PHM-SI series combines 30 % higher ripple current than previous-generation components with a long useful life.
The devices introduced today have ripple currents up to 4.42 A, and it enables designers to utilize fewer components to save board space and lower costs. Their long useful life of 3,000 hours at 105 °C permits use in demanding applications requiring more than 10 years of a lifetime from capacitors in ambient temperatures up to 60 °C.
The Key Feature of the Vishay Capacitors include
- A cylindrical aluminum case, insulated with a blue sleeve,
- 259 PHM-SI series devices feature rated voltages to 500 V in 25
- Compact case sizes ranging from 22 mm by 25 mm to 35 mm by 60 mm.
- The RoHS-compliant capacitors are also available with 3-pin keyed polarity snap-in terminals.
As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the devices are ideally suited for buffering, filtering, and energy storage in compact power applications, including power supplies for server farms or industrial tools such as plasma cutters; motor drives for compressors in industrial cooling systems; and industrial lamp drivers for UV water treatment systems.
Samples and production quantities of the 259 PHM-SI series capacitors are available now, with lead times of 15 weeks.
