Types MC and MCN Multilayer RF Capacitors
Specications
Quality Factor (Q) is as fol-
lows when measured at 1 MHz
Capacitance Min. Q
Range
1 to 80 pF 500 to 3000
>80 pF 3000
Insulation Resistance is no less
than 100 GΩ when measured at 100
Vdc
Withstanding voltage is two
times the rated voltage between 5
seconds and without damage: with
50 mA or less current.
Life Test: Subject capacitors to
125 ºC ±3 ºC with 1.5 times rated
voltage applied for 2000 (+72, –0)
hours. There will be no visual dam-
age and the capacitors will meet the
limits of the table below.
Vibration Resistance: Subject
the capacitors to simple harmonic
motion with an amplitude of 0.06
inches; vary the frequency uniformly
from 10 to 55 Hz and return to 10 Hz,
all in one minute. Repeat that cycle
continuously for two hours in
After-Test Limits
each of three mutually perpendicular
directions. There will be no visual
damage and the capacitors will meet
the limits of the table below.
Bending Test: Mount the capaci-
tor as shown below and press the ram
bar until a 2.0 mm deflection is
achieved. There will be no visual
damage and the capacitors will meet
the limits of methods JIS 5102 8.11
and AEC-Q200-005 without crack-
ing or visual damage.
Moisture Resistance: Subject
the capacitors to 40 ±2 ºC at 90 to
95% humidity for 500 (+24, –0)
hours. Return to room ambient for
24 hours. There will be no visual
damage and the capacitors will meet
the limits of the table below.
Temperature Coefcient and
Drift: Measure the capacitors’
capacitance at 25 ºC, –55 ºC, 25 ºC,
125 ºC and at 25 ºC — all ±3 ºC —
after stabilizing at each temperature.
The capacitor will meet the limits of
the Characteristic table in Ordering
Information.
Heat Resistance: Subject the
capacitors to 125 ±2 ºC for 2 (+1,–0)
hours. Then the insulation resistance
will be no less than 5GΩ.
Solderability: After 2 ±0.5 sec-
onds in molten solder with Sn-PB
between molten and solder at 235 ±5
ºC, solder coverage will be no less
than 75% when examined at 10X
magnication for ow soldering.
Solder Heat Resistance: Sub-
ject the capacitors to molten solder
at 250±5 ºC for 5±0.5 seconds after
10 to 30 seconds pre-heating at 80
to 120 ºC. There will be no visual
damage and the capacitors will meet
the limits of the table below.
