Dc Link Capacitors By Kowary Technology Co., Ltd.

1) Features of DC-Link Capacitors
Metallized film, dry construction, UL94V-0 resin end filled, non-inductive type.
Wide capacitance range, high voltage, long useful life, non polar dielectric.
Over voltage withstanding up to 1.5 or 2Un, high ripple current.
Possible to replace Electrolytic capacitors in some cases.
Coating: Aluminum case, fire-retardant plastic case (UL 94 V-0), or polyester tape wrapping(Axial)
Terminals: Tinned copper wire, or copper bolt nuts, with copper bolt in the bottom.

2) Applications
Widely used in solar and wind power inverter, electric vehicles, motor drives, welders, induction heating equipment, large-scale switching power supplies and other power electronic devices for filtering or energy storage.
