10 µF Feed-Thru Capacitors
for RFI/EMI test setups
The feed-thru capacitor is used for added filtering in conjunction with line impedance stabilization networks. The 10 µF feed-thru capacitor can also be used as a power-line filter installed in the wall of a shielded enclosure or equipment cabinet. The capacitor provides adequate insertion loss without suffering the power current saturation limitation of conventional filters which employ toroidal inductors.
The threaded feed-thru stud will accommodate power current of the listed rating without heating or voltage loss. Table 2 indicates available current and voltage ratings of the various Solar 10 µF Feed-Thru Capacitors. All have low dissipation factors, high temperature ratings, high insulation resistance, doubly rated dielectric strength, and long life characteristics. To satisfy safety requirements, a bleeder resistor is included within the capacitors, which serves to discharge the capacitors when applied voltage is removed.
|Capacitance: 10 µF
|Temperature: -55°C to +70°C @ rated voltage +105°C @ 50% of rated voltage
