* Please consult Panasonic if your condition exceeds the above spec.
*Permissible voltage graph is the case of sine waveform. When you use this product, peak voltage must not exceed DC rated voltage.
*The current value (Aop) is calculated using "nominal capacitance." In fact, it changes by the tolerance of a capacitance value, capacitance change, etc.

Caution about Safety in Use
3.1. Washing of chip type
●Since the chip type capacitor does not
have a coating, components of flux or detergent left over
on the element at the time of washing may be activated
and invade into the inside of the capacitor,
and adverse effects may be caused. Observe the
following cautions.
●In the case of washing, use flux and cream solder with
halogen content of 0.1wt.% or less when mounting.
●In the case of ultrasonic washing, note that peeling of
protective film, electrode separation due to resonance,
or characteristic deterioration may occur depending on
the detergent used or ultrasonic output. Check
carefully beforehand.
●When using a CFC substitute detergent, with the
washing method of spraying detergent (rinsing water)
to the substrate at high pressure, the
protective film on the element surface may
be peeled off due to the water pressure. Check
carefully beforehand.
2.4.2 Cautions for use of soldering iron
●Be careful that the soldering irons do not directly touch
the main body of the chip film capacitor. In particular,
don’t touch the side (cut section). If touched by the
heated soldering iron, lowering of insulation resistance,
shortcircuit or other characteristic deterioration may
occur.
●Preheat the printed wining board land sufficiently with
the soldering iron, and then solder. Solder without directly
touching the iron tip to the electrode of the capacitor.
●Don’t reuse the products once removed by the soldering
irons.
●Should not mount the chip film capacitors in the mass
production by soldering iron. (The temperature
control is difficult, and the characteristics may
be deteriorated.)
●Should not resolder with heat directly from
bottom side of P. W. Board. because capacitor will likely
be damaged.

<CFC substiture detergent>
As a result of regulation of CFC and chlorine derivative
detergents, many substitute detergents come to be used,
but the performance of the chip type capacitor may be
reduced depending on the type of detergent or washing
condition. Check sufficiently beforehand. Consult us in
advance if planning to use CFC substitute detergent.
3.2. Washing of leaded type
The film capacitor varies significantly in the effect of
washing depending on the structure and material, and
generally it is less affected by CFC or alcohol
derivative washing solvent, and is likely to be affected
by highly polar solvent.
The lead type film capacitor is coated with an epoxy
resin excellent in chemical resistance, and is hardly
affected by detergent, but it is recommended to be
washed for short duration.
<Drying after washing>
Dry after washing so that the detergent is not left over. If
drying is insufficient, the detergent is left over on the
element surface, and the insulation resistance is measured
to be lowered. Dry enough so as not to leave detergent.
Applicability of detergents in film capacitors is listed for
reference.
Design,Specifications are subject to change without notice. Ask factory for technical specifications before purchase and/or use.
