JAMES has a comprehensive line of capacitors in metal cases (up to 525V ratings) and plastic cases
(up to 400V ratings). All Universal capacitors are designed for 60,000 hours of continuous life. They’re
exceptionally reliable because we put them through accelerated life testing at 125% rated voltage and
rated temperature +10°C.

A capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have know the battery works, then you know that a battery has two terminals. Inside the battery, chemical reactions produce electrons on one terminal and absorb electrons on the other terminal. A capacitor is much simpler than a battery, as it can't produce new electrons -- it only stores them.
JAMES capacitors are normally packaged with ballasts. They may also be ordered separately, bulk
packaged, or individually boxed with the suffix “BH” (metal cases only). Capacitor weights vary from
1/4 lb. to 1 lb. each.
