Abstract
Abstract A capacitor arrangement comprising a pair of line to ground planar capacitors with electrical terminals on each side with a grounding tab connected to the electrical terminals on the first sides of the line to line capacitors, and with a pair of hair pin leads, respectively, connected to the terminals on the second sides of the line to ground capacitors. A modified form includes a line to line capacitor connected between the line to ground capacitors with very short leads so as to reduce the inductance.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
251 words
A capacitor arrangement comprising, first and second planar line to ground capacitors with electrical terminals on opposite sides thereof, an electrical conducting grounding tab electrically connected to first sides of said first and second line to ground capacitors, a line to line capacitor with electrical terminals on first and second ends thereof and positioned so that its ends are closely adjacent to said electrical terminals on the second sides of said first and second line to ground capacitors, respectively, a first short lead portion connected between the electrical terminal on the second side of said first line to ground capacitor and the electrical terminal on the first end of said line to line capacitor, a second short lead portion connected between the electrical terminal on the second side of said second line to ground capacitor and the electrical terminal on the second end of said line to line capacitor, a third lead portion attached to the electrical terminal on the first end of said line to line capacitor, a fourth lead portion attached to the electrical terminal on the second side of said first line to ground capacitor and said third and fourth lead portions extending parallel to each other, a fifth lead portion attached to the electrical terminal on the second end of said line to line capacitor, a sixth lead portion attached to the electrical terminal on the second side of said second line to ground capacitor and, said fifth and sixth lead portions extending parallel to each other.
Claim 2
Dependent Claim
251 words
A capacitor arrangement comprising, first and second planar line to ground capacitors with electrical terminals on opposite sides thereof, an electrical conducting grounding tab electrically connected to first sides of said first and second line to ground capacitors, a line to line capacitor with electrical terminals on first and second ends thereof and positioned so that its ends are closely adjacent to said electrical terminals on the second sides of said first and second line to ground capacitors, respectively, a first short lead portion connected between the electrical terminal on the second side of said first line to ground capacitor and the electrical terminal on the first end of said line to line capacitor, a second short lead portion connected between the electrical terminal on the second side of said second line to ground capacitor and the electrical terminal on the second end of said line to line capacitor, a third lead portion attached to the electrical terminal on the first end of said line to line capacitor, a fourth lead portion attached to the electrical terminal on the second side of said first line to ground capacitor and said third and fourth lead portions extending parallel to each other, a fifth lead portion attached to the electrical terminal on the second end of said line to line capacitor, a sixth lead portion attached to the electrical terminal on the second side of said second line to ground capacitor and, said fifth and sixth lead portions extending parallel to each other.
