Plastic Film Capacitors

When using film capacitor of low heat resisting temperature in mounting, measure the element temperature profile in mounting

in the following manner, and make sure the soldering is done below the heat resisting temperature.

＜Preparation of measuring sample＞

Open a hole of about Φ0.3 mm to 0.8 mm in the top of the capacitor to the middle of the element, and insert

thermocouple (ø0.1T wire), and fix with adhesive.

＜Measurement of temperature profile＞

As shown below, connect a thermocouple (3 - 4 )m of same type as the thermocouple attached to the capacitor, to

the thermocouple of the capacitor as shown below. Mount the sample on the mounting printed wiring board, and

pass into the soldering andmountingprocess,andmeasurethe temperature profile.

・ When using a capacitor across the line as means for prevention of noise, not only is the supply voltage is always applied,

but also abnormal surge such as lightning is applied, which may lead to smoke or fire. Therefore, the across-the-line

capacitors are strictly regulated in safety standard in each nation, and it is necessary to use the product conforming to

the standard.

For using across the line in Japan, use the following models or the above overseas authorized ones.

ECQE(F)

: 1000 V.DC (125 V.AC) rating

ECQE(F)

: 1250 V.DC (125 V.AC) rating

ECQE(F)/(B)/(T)

: 125 V.AC (1A) rating

ECQE(F)/(T)

: 250 V.AC (2A) rating

However, when using the ECQE(F)1A/2A, ECQE(B)1A , ECQE(T)1A/2A rating model as across-the-line capacitor, at least

one of the following conditions must be satisfied.

(1) A varistor with the voltage of the value or lessshown in the following table should be connected to the capacitor in

parallel.

(2) A pulse voltage more than the value shown in the table below should not be applied across the capacitor.

Note : When using together with varistor, check the varistor specification, and select the one free from surge

deterioration.

When Safety standard approval capacitor is used for necessary equipment, please use items of the following table.

＜Representative examples of models authorized in major safety standards in the world＞

* Please contact us about CQC (China).

・ In the case of the voltage dropper usage,　when an abnormal voltage of the surge voltage etc. is applied the capacitance

decrease is caused, such as the fuse function in the capacitor operates.In the worst case, the capacitor does not work as

voltage dropper. So, please notice an abnormal voltage. At that time, high voltage may be applied to the load side.

Therefore, please provide protective means for safety.

The products are tested based on all or part of the test conditions and methods defined in AEC-Q200.

Please consult with Panasonic for the details of the product specification and specific evaluation test results, etc., and please

review and approve Panasonic's product specification before ordering.
