FAILURE RATE LEVEL
(Established at 90% confidence):
M - - 1% per 1000 hours
P - - 0.1% per 1000 hours
R - - 0.01% per 1000 hours
S - - 0.001% per 1000 hours
STYLE: Identifies dimensions of the
capacitor and lead type, where applicable.
RATED TEMP: -55°C to +125°C
VOLTAGE TEMP. (TCC) LIMITS:
G = +90 ±20 PPM/°C; P = 0 ±30 PPM/°C
CAPACITANCE CODE: The first two digits represent
significant figures and the last digit specifies the number
of zeros to follow. When fractional values of pF are required,
the letter R shall be used to indicate the decimal point.
RATED DC VOLTAGE @ 125°C:
A - - 50 VDC, B - - 100 VDC, C - - 200 VDC,
D - - 300 VDC, E - - 500 VDC, K - - 150 VDC
TERMINATION FINISH:
N - Gold over Nickel over Silver (CDR11, CDR13)
S - Solder Coated, Final (CDR12, CDR14, CDR23, CDR25)
T - Silver (CDR21, CDR22, CDR24)
U - Solder Coated, Nickel Barrier (CDR12, CDR14)
N and U - Terminations preferred for best solder-
ability, thermocompression bonding, leach and mig-
ration resistance, and shelf life for chips and pellets.
W - Solder plated, nickel barrier (CDR12, CDR14, not
for new designs)
Z - Solder plated, nickel barrier (CDR12, CDR14)
CAPACITANCE TOLERANCE:
B (±0.1 pF), C (±0.25 pF), D (±0.5 pF), F (±1%),
G (±2%), J (+5%), K (±10%), M (±20%)
