Disc Ceramic Capacitors
Professional Ceramic Capacitors - Class I, II and III
MIL-STD-202F
The professional ceramic disc capacitors were specially
developed for applications in severe environmental condi-
tions, high humidity, temperature, gas, vapor and solvents.
The capacitors are flame retardant epoxy coated, meeting
UL 94-V0 flammability specifications. The capacitors are
100% screened on following electrical parameters:
Capacitance, loss factor, test voltage. After the 100% test,
the capacitors are audited on its electrical and mechanical
parameters with following AQL:
Electrical parameters: 0.065% level II
Mechanical parameters: 0.65% level II
The capacitors withstand the following reliability essays:
Terminal strength: method 211 – condition A
Resistance to solvents: method 215
Resistance to soldering heat: method 210 – condition B
Solderability: method 208
Thermal shock: method 107 – condition A
Humidity (steady state): method 103 – condition D
Life (at elevated ambient temperature): method 108 –
condition D
Operating temperature and storage: -55... +125º C

Disc Ceramic Capacitors
General Specifications - Class III Professional
DIELECTRIC - CLASS III
A thin dielectric layer is grown on a disc of conductive
ceramic. Very large capacitances can be obtained due to
reduced thickness of this barrier layer and its inherently
high dielectric constant. Due its small dimensions, they are a
less expensive replacement of multilayer ceramic or poly-
ester capacitors.
