Terminations

Bending strength load listed in the table below shall be hung at the end of the lead wire termination, and the

body of a capacitor shall be bent 90o and return to its original position. This operation shall be performed

around 2 to 3 seconds. Then the body shall be bent 90°at the opposite direction and return to its original

position at same speed. At this test, that capacitor shall no appear any change defective in use.

Solderability

A lead wire termination shall be dipped for 2±0.5 seconds in the flux of ethanol or isopropylalcohol

solution (25±2%) of colophonium. Then that lead wire terminations shall be immersed to a solder

(H60A, H60S or H63A) of 235±5

⁰C and up to the point 1.5 to 2.0mm from the body and kept for

2±0.5 seconds, and pulling it out. After this test, at least 95% of circumferential surface of the dipped

portion of termination shall be covered with new solder.

Resistance to

Soldering Heat

A Capacitor shall be inserted to a printed circuit board having a thickness of 1.6mm up to the point 1.5 to

2.0mm from the body. Then the lead wire termination shall be dipped for 5 to 10 seconds in the flux of ethanol

solution (25±2%) of colophonium. And then the lead wire termination shall be immersed to the solder (H60A,

H60S or H63A) of 260±5

⁰C and up to the point of the Printed circuit board and kept for 10±1 seconds, and

pulling it out. After this test, characteristics shall meet the value in the table below.

1. Cautions on use of capacitors

a. Polarity

Solid electrolytic capacitors are polarized capacitors. Use capacitors after verifying their positive and negative

polarities. If these capacitors are installed in the reverse polarity, its life may shorten because of increasing

leakage current or short circuit.

b.

Types of circuits in which capacitors are prohibited from being used PEHA series may be

heated by soldering to increase in its leakage current slightly. This may have some influence

on the characteristics capacitors in the following circuits.

(1) Time constant circuit

(2) Coupling circuit

(3) High impedance voltage holding circuit

(4) Connections of two or more capacitors in series for higher withstand voltage.

c. Over voltage

If PEHA series is applied a voltage higher than the rated voltage for an instantaneous period, it may be

defected due to short circuit. Note that the voltage over the rated voltage must not be applied to capacitors.
