Abstract
A low inductance multi-layer capacitor. The capacitor comprises interleaved parallel internal electrode plates with dielectric there between. Each internal electrode plate comprises two lead-out tabs and is generally T shaped. A first external electrode terminal is electrically connected to the lead-out tabs of the even internal electrode plates, and a second external electrode terminal is electrically connected to the lead-out tabs of the odd internal electrode plates. The external electrode terminals are on a common first exterior surface and a common opposing second exterior surface of the capacitor.
Claims18
A capacitor comprising:
- first internal electrode plates;
- second internal electrode plates arranged parallel to said first internal electrode plates with dielectric between;
- wherein said first internal electrode plates comprise a first and second lead-out tab, a first land, and a first end;
- wherein said second internal electrode plates comprise an opposing third and fourth lead-out tab, a second land, and a second end;
- a first external electrode terminal electrically connected to said first internal electrode plates by said first and second lead-out tab;
- a second external electrode terminal electrically connected to said second internal electrode plates by said opposing third and fourth lead-out tab;
- and
- wherein said first external electrode terminal and said second external electrode terminal are on a common first exterior surface and a common opposing second exterior surface of the capacitor.
A capacitor comprising:
- m interleaved internal electrode plates;
- wherein each internal electrode plate of said m internal electrode plates are arranged spaced apart in parallel with dielectric between;
- wherein m is an integer greater than 1;
- wherein each said internal electrode plate comprises a first and second lead-out tab, a land, and an end;
- a first external electrode terminal electrically connected to said first and second lead-out tab of even ones of said m internal electrode plates;
- a second external electrode terminal electrically connected to said first and second lead-out tab of odd ones of said m internal electrode plates;
- and
- wherein said first external electrode terminal and said second external electrode terminal are each arranged on a common first exterior surface, a common opposing exterior surface, and a perpendicular face between said first exterior surface and said opposing exterior surface of the capacitor.
