SCOPE
1.1
Purpose. This specification defines the general requirements for high reliability, ceramic
dielectric, multilayer, fixed value chip capacitors for space, missile and other high reliability
applications. It defines the test and qualification parameters for extended range capacitors
required by the very low power, low voltage assemblies used for flight.
1.2
Part or Identifying Number (PIN). The complete PIN for the Multilayer Chip Capacitors
supplied to this specification shall be specified as follows. Allowable combinations of voltage,
capacitance, dielectric type, and package size shall be described in Table I herein.

1.2.1 Ultrasonic examination. Devices supplied to this specification shall be subjected to
ultrasonic examination in accordance with the manufacturer’s standard procedures and
MIL-PRF-123, except as modified herein. 100% inspection complies with the MIL-PRF-123
sample requirements. Ultrasonic examination may be performed prior to capacitor termination
(in accordance with MIL-PRF-123 requirements) or after capacitor termination, at the
manufacturer’s option.
1.2.2 Dielectric Type. The voltage temperature characteristic shall be referenced to the +25°C
value, and shall be applicable over the entire temperature range of -55°C to +125°C. Dielectric
type NPO (“N”) shall be 0 ±30 ppm/°C, and dielectric type X7R (“X”) shall be +15, -15 percent.
1.2.3 Termination. Devices supplied to this specification shall have a termination coating of
palladium silver alloy (MIL-PRF-123, type M), or base metal barrier tin-lead solder
(MIL-PRF-123, type Z) plated, or base metal barrier gold (MIL-PRF-123, type G) plated. Tin
lead solder plating shall contain a minimum of 4% lead, by mass. Note that the palladium silver
alloy termination coating is not recommended for applications using eutectic solder attach
methods; PdAg termination coating is appropriate for conductive epoxy mounting techniques
only.
1.2.4 Package/Marking. Capacitors supplied to this specification may be supplied as unmarked
or marked, as designed by the marking identifier code in the GSFC PIN. Capacitors shall be
unmarked, and packaged on 7” tape and reel (identifier code 1), or in waffle packs (identifier
code 3). Capacitors shall be marked per the manufacturer’s standard marking procedure and
nomenclature (or MIL-PRF-123 nomenclature), and packaged on 7” tape and reel (identifier
code 2), or in waffle packs (identifier code 4). For marked capacitors, size codes smaller than
0805 (A, B, C, D, L, M, N, and P) are not available, due to physical size constraints.
