3. REQUIREMENTS

3.1 Item requirements. The individual item requirements shall be in accordance with MIL-PRF-123 including those for deliverables

data, production lot definition, and traceability, and as specified herein. These capacitors shall be capable of meeting all design,

electrical, environmental, and mechanical requirements of MIL-PRF-123, unless otherwise stated.

3.2 Interface and physical dimensions. The interface and physical dimensions shall be as specified in MIL-PRF-123 and herein (see

figure 1).

3.2.1 Tin plated finishes. Tin plating is prohibited as a final finish or as an undercoat. Tin-lead (Sn-Pb) finishes are acceptable

provided that the minimum lead content is 4 percent.

3.3 Electrical characteristics.

3.3.1 Dielectric type. The dielectric type shall be BG (90

±20ppm/°C), or BP (0 ±30 ppm/°C) ceramic in accordance with

MIL-PRF-123.

3.3.5 Equivalent series resistance. In accordance with MIL-PRF-55681.

3.3.6 Series Resonance. In accordance with MIL-PRF-55681.

3.4 Marking. Marking shall be as specified in MIL-PRF-123. In addition, these capacitors shall be marked with a contrasting color dot

placed on the side of the capacitor to indicate the vertical plate orientation to that side. When laser marked, the marking shall be on the

surface which is parallel to the plane of the embedded electrodes (this is the larger area which is normally the imprint area). If the

capacitor is so marked, the vertical plane orientation is defined; therefore the contrasting color dot on the capacitor to indicate vertical plate

orientation to that side is optional. Packaging shall be marked as specified in MIL-PRF-123 except the PIN shall be as specified in 1.2 and

the “JAN” brand is not applicable.

3.5 Manufacturer eligibility. To be eligible for listing as an approved source of supply, a manufacturer shall be listed on the

MIL-PRF-55681/4 Qualified Products List for “S” failure rate level.
