Abstract

An embodiment of an electronic system comprises a main board, and a modular capacitor subassembly mechanically and electrically coupled to the main board, wherein the modular capacitor subassembly provides backup power for the main board, and wherein the main board is adapted for use in at least two housing form factors. Other embodiments are disclosed and claimed.

First claim

What is claimed is:

1. An electronic system, comprising:
a main board which is adapted for use in any of at least two housing form factors which are each defined in an Enterprise & Datacenter Solid-State Drive Form Factor standard;
a socket connector mechanically and electrically coupled to the main board; and
a modular capacitor subassembly comprising:
a daughter board which is mechanically and electrically coupled to the main board via two connector leads which are plugged each into a respective one of two sockets of the socket connector, the daughter board comprising a first surface, wherein a first edge of the first surface is opposite a second edge of the first surface;
a first one or more capacitors arranged along the first edge, wherein for each capacitor of the first one or more capacitors, a respective two leads extend from a respective first end of the capacitor, and across the first edge, to couple the capacitor to the daughter board; and
a second one or more capacitors arranged along the second edge, wherein for each capacitor of the second one or more capacitors, a respective two leads extend from a respective second end of the capacitor, and across the second edge, to couple the capacitor to the daughter board;

wherein:
the respective first ends of the first one or more capacitors face the respective second ends of the second one or more capacitors; and
the first one or more capacitors and the second one or more capacitors are electrically coupled to provide backup power for the main board via the two sockets.

2. The electronic system of claim 1 , wherein the socket connector comprises a through board socket.

3. The electronic system of claim 2 , wherein the modular capacitor subassembly comprises two or more leads plugged into the through board socket perpendicular to the main board.

4. The electronic system of claim 1 , wherein the socket connector comprises a surface mount socket.

5. The electronic system of claim 4 , wherein the modular capacitor subassembly comprises two or more leads plugged into the surface mount socket parallel to the main board.

6. The electronic system of claim 1 , wherein a thickness of the first one or more capacitors is in accordance with a thickness of one of the at least two housing form factors.

7. The electronic system of claim 1 , wherein the main board comprises a processor motherboard.

8. The electronic system of claim 1 , wherein the main board comprises a solid state drive main board.

9. A modular capacitor apparatus, comprising:
a daughter board comprising a first surface, wherein a first edge of the first surface is opposite a second edge of the first surface;
a first one or more capacitors arranged along the first edge, wherein for each capacitor of the first one or more capacitors, a respective two leads extend from a respective first end of the capacitor, and across the first edge, to mechanically and electrically couple the capacitor to the daughter board;
a second one or more capacitors arranged along the second edge, wherein for each capacitor of the second one or more capacitors, a respective two leads extend from a respective second end of the capacitor, and across the second edge, to couple the capacitor to the daughter board; and
a connector electrically coupled to each of the first one or more capacitors and the second one or more capacitors via the daughter board, wherein the connector is to be mechanically and electrically coupled to a main board to enable the first one or more capacitors and the second one or more capacitors to provide backup power to the main board;

wherein the respective first ends of the first one or more capacitors face the respective second ends of the second one or more capacitors.

10. The modular capacitor apparatus of claim 9 , wherein the connector includes two or more leads arranged to couple perpendicular to the main board.
