CERAMIC HIGH RELIABILITY MOLDED & CHIPS
GENERAL INFORMATION MIL-C-123
INTRODUCTION
MIL-C-123 specification covers the general requirements for high
reliability, general purpose (BX) and temperature stable (BP) ceramic
dielectric fixed capacitors for space, missile, and other high reliability
applications. Capacitors covered by MIL-C-123 may be used in criti-
cal frequency determining applications, timing circuits, and other
applications where absolute stability is required (BP) and in applica-
tions where appreciable variations in capacitance with respect to
temperature, voltage, frequency, and life can be tolerated (BX).
SCREENING TESTS
Each lot has the following In-Process Inspections performed:
1. 100% Ultrasonic Scan
2. n-Process Destructive Physical Analysis
3. 100% visual inspection at a minimum of 10X magnification
4. Pre-encapsulation terminal strength evaluation (leaded devices
only). Radial leaded capacitors must meet a minimum lead pull

The following Group A shall be performed on each lot:
1. Thermal Shock—Performed in accordance to MIL-STD-202,
Method 107, Condition A, with step 3 being 125°C. Number of
cycles shall be 20 (100% of lot).
2. Voltage Conditioning—The voltage conditioning shall consist
of applying twice the rated voltage to the units at the maximum
rated temperature of 125°C for a minimum of 168 hours and a
maximum of 264 hours. The voltage conditioning may be termi-
nated at any time during 168 hours to 264 hours time interval
that confirmed failures meet the requirements for the PDA dur-
ing the last 48 hours listed in Table I below (100% of lot).
Optional Voltage Conditioning (Accelerated Voltage
Conditioning)—AII conditions of the standard voltage condi-
tioning apply with the exception of the increased voltage and the
decreased test time. (Refer to Mil-C-123 for formula.)
*Step 5 is performed on chips at this point (100% of lot).
3. Dielectric Withstanding Voltage 250% of the dc rated voltage
at 25°C (100% of lot).
4. Insulation Resistance—The 25°C measurement with rated
voltage applied shall be the lesser of 100,000 megohms or 1000
megohm-microfarads (100% of lot).
*5.Insulation Resistance—The 125°C measurement with rated
voltage applied shall be the lesser of 10,000 megohms or 100
megohm-microfarads (1000% of lot). For chips 125°C IR is per-
formed prior to step 3 above.
6. Capacitance must be within specified tolerance at 25°C (100%
of lot). Cap Exclusion: Capacitance values no more than 5% or
.5 pF, whichever is greater, for BX characteristics or 1% or .3 pF,
whichever is greater, for BP characteristics beyond specified
tolerance limit shall be removed from the lot but shall not be con-
sidered defective for determination of the PDA.
7. Dissipation Factor shall not exceed 2.5% for X dielectric,
0.15% for G dielectric at 25°C (100% of lot).
8. Percent Defective Allowable (PDA). The following table lists
the PDA requirements for MIL-C-123 Group A:

SAMPLE TESTS
The following Group B tests shall be performed on samples from
each lot, which have been subjected to and have passed Group A
inspection.
1. Thermal Shock—Performed in accordance to MIL-STD-202,
Method 107, Condition A, with step 3 being 125°C. Number of
cycles shall be 100.
2. Life Test per MIL-5TD-202, Method 108. Test temperature and
tolerance is +125°C +4, -0°C. Capacitors shall be subjected to
2X rated voltage for 1000 hours.
3. Humidity, steady state, low voltage per MIL-STD-202,
Method 103, Condition A. Capacitors shall be subjected to an
environment of 85°C with 85% relative humidity for 240 hours
minimum. Cycling shall not be performed. A dc potential of 1.3
±0.25 volts shall be applied continuously through a 100,000
ohm resistance to each device under test. At completion, 25°C
IR and Cap are read.
4. Voltage-temperature limits—Capacitance is measured at var-
ious temperatures (-55°C to +125°C) with and without rated
voltage.
5. Moisture Resistance per MIL-STD-202, Method 106. There
shall be 20 continuous cycles. During the first 10 cycles only, a
dc potential of 50 volts shall be applied across the capacitor ter-
minals. Once each day, a check shall be performed to deter-
mine whether a capacitor has shorted. Vibration cycle of MIL-
STD-202, Method 106, Step 7b shall not be performed. Upon
completion of MIL-STD-202, Method 106, Step 6 of the final
cycle, capacitors shall be measured for capacitance, dielectric
withstanding voltage and insulation resistance.
The following Group C tests shall be performed on samples selected
from lots that have passed Group A and have been submitted for
Group B inspection. Samples shall be selected every two months.
1. Terminal Strength
2. Solderability
3. Resistance to Soldering Heat
4. Solvent Resistance (Leaded devices only)
All lots shipped must have been subjected to and passed Group A
and B testing.
