PEEP Series

i. Parallel connection

If PEHA series is connected with another type of a capacitor in parallel, larger ripple current

may flow through one of capacitors. Take the current balance among them into account in

circuit designs.

j. Using temperature and frequency

The electric characteristics of capacitors depend on the variations of the ambient

temperature and frequency. Check the variations in designing circuits.

3. Notes on installation of capacitors

a. Notes on pre-installation of capacitors

(1) Do not reuse capacitors installed in a unit with the power supply turned on for another unit. No used

capacitors shall be reused excluding those removed to measure their electric characteristics in periodical

inspection.

(2) If PEHA series stored for a long period may often increase in its leakage current, connect a resistor of

approximately 1KΩ to the capacitors for voltage treatment.

b. Notes at installation of capacitors

(1) Install capacitors in a unit after confirming that their ratings (rated capacitance and rated voltages) meet

the conditions of the unit.

(2) Install capacitors in the correct polarities.

(3) Take care not to drop capacitors on floors. Do not use capacitors dropped on floors.

(4) Do not deform capacitors to install them in units.

(5) Install PEHA series on a printed circuit board after confirming that its lead pitch is equivalent to the

corresponding hole pitch.

(6) At the picking, mounting, and locating by an automatic inserter or the cutting of the leads of PEHA series

by an automatic mounter, some stress may be applied to the PEHA series. Take note on the shock.

(7) Do not apply any excess force with the terminals of capacitors.

c. Heating

In preheating or heating for adhesion and fixing of other electronic components, the

temperature put to capacitors should be less than 120

⁰C. The total heating period should be

shorter the 90 seconds.

d. Soldering by soldering iron

(1) Capacitors should be soldered under the conditions as follows:

The iron tip at the temperature of 400±10

⁰C or less may be put to each lead of PEHA series for <3±1 sec.

(2) Lead wire terminations of capacitors may be required to be processed because terminals is not equivalent

to that of corresponding holes on the printed circuit board. Process terminations so that no stress may be

applied to capacitors themselves before soldering.

(3) Do not make the tip pf a soldering iron be in contact with capacitors themselves.

(4) The leakage current of soldered capacitor may increase slightly depending on several conditions including

pre-heating, soldering temperature and period, and board material and thickness, soldering temperature

and period, and board material and thickness. However, the leakage current decreases gradually by the

self-repair characteristic of capacitors when they are used with voltage application.

e. Flow soldering

(1) Do not dip capacitor themselves into melted solder in soldering. Only provide soldering for the board

surface in the backside of the surface on which the capacitors are mounted

.

(2) Solder capacitors under the soldering conditions as follows.

(i)

Pre-heat condition: atmosphere temperature 120

⁰C or less for up to 90 sec.

(ii)

Soldering condition: solder temperature 260

⁰C or less for up to 10 sec.

(3) Note that flux may not adhere to any substances except lead wires.

(4) Do not make any other components fallen at capacitors in soldering.
