ATC RF/Microwave Capacitors: Military Products ATC is a QPL Approved Supplier for MIL-PRF-55681/4 and /5 Products Listed Below This manual covers the general requirements for established reliability fixed, multilayer, unencapsulated, monolithic porcelain and ceramic dielectric capacitors. These capacitors are intended for use in RF solid state circuitry up to and including 25 gigahertz and cannot be replaced in the field. The porcelain dielectric (Characteristic BG) has a temperature coefficient of +90 20 PPM/C over the temperature range of -55C to +125C. The ceramic dielectric (Characteristic BP) has a temperature coefficient of 0 30 PPM/C over the temperature range of -55C to +125C. The minimum, self-resonant frequencies of the capacitors are specified. For example, a 1 pF size B is specified as 6 GHz. minimum. ATC PART NUMBER CODE: CDR 12 B G 101 A F W S DESIGNATION: Identifies established reliability, ceramic dielectric, fixed, chip capacitors. 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. 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 solderability, thermocompression bonding, leach and migration resistance, and shelf life for chips and pellets. W - Solder plated, nickel barrier (CDR12, CDR14) RATED TEMP: -55C to +125C VOLTAGE TEMP. (T.C.) 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.
