Chip Monolithic Ceramic Capacitors
Medium-voltage High-Capacitance for General-Use
s Features
1. A new monolithic structure for small, high
capacitance capable of operating at high voltage
levels.
2. Sn-plated external electrodes realized good
solderability.
3. Use the GRM18/21/31 types with flow or reflow
www.DataSheesto4lUd.ecroimng, and other types with reflow soldering
only.
s Applications
1. Ideal for use as a hot-cold coupling for DC/DC
converter.
2. Ideal for use on line filters and ringer detectors
for telephones, facsimiles and modems.
3. Ideal for use on diode-snubber circuits for
switching power supplies.

No failure should be observed when 150% of the rated voltage
(200% of the rated voltage in case of rated voltage : DC250V,
120% of the rated voltage in case of rated voltage : DC1kV) is
applied between the terminations for 1 to 5 sec., provided the
charge/discharge current is less than 50mA.
The insulation resistance should be measured with DC500T50V
(DC250T50V in case of rated voltage : DC250V) and within 60T5
sec. of charging.
The capacitance/D.F. should be measured at 25D at a frequency
of 1T0.2kHz and a voltage of AC1T0.2V (r.m.s.)

Solder the capacitor to the testing jig (glass epoxy board) shown
in Fig. 1 using a eutectic solder.
Then apply 10N force in the direction of the arrow.
The soldering should be done either with an iron or using the
reflow method and should be conducted with care so that the
soldering is uniform and free of defects such as heat shock.

Solder the capacitor to the test jig (glass epoxy board).
The capacitor should be subjected to a simple harmonic motion
having a total amplitude of 1.5mm, the frequency being varied
uniformly between the approximate limits of 10 and 55Hz. The
frequency range, from 10 to 55Hz and return to 10Hz, should be
traversed in approximately 1 min. This motion should be applied
for a period of 2 hrs. in each 3 mutually perpendicular directions
(total of 6 hrs.).
