1.2.1 Dielectric. The dielectric type is identified by the following 2 letters as defined in 3.3.1: BP or BG.
1.2.2 Capacitance value. The nominal capacitance value, expressed in picofarads (pF) is identified by a three digit number; the first
two digits represent significant figures and the last digit specifies the number of zeros to follow. When the nominal value is less than
10 pF, the letter “R” is used to indicate the decimal point and the succeeding digit(s) of the group represent significant figure(s). 1R0
indicates 1.0 pF; R75 indicates .75 pF; and 0R5 indicates 0.5 pF. See table IV for values.
1.2.3 Voltage. The rated voltage for continuous operation at +125°C is identified by a single letter as shown in table I.

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.

All capacitance values:
≤
0.15%
BG
All capacitance values:
≤
0.05%
3.3.4 Insulation resistance. At +25°C: 10 megohms, minimum
5
At +125°C: 10 megohms, minimum
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.
