Product specification
Polypropylene film foil capacitors
KP 460 to 464
CONSTRUCTION
Description
Low-inductive wound cell of metal foil and a
polypropylene film
Protected by a hard, water-repellent solvent-resistant blue
epoxy lacquer
Axial iron leads, solder-coated.
Mounting
N
ORMAL
USE
The capacitors are suitable for vertical or horizontal
mounting on printed-circuit boards. The capacitors packed
on bandoliers are designed for mounting on printed-circuit
boards by means of automatic insertion machines.

CONDITIONS
The capacitance stability is dependent on the maximum
temperature the capacitor reaches during soldering.
Figure 11 shows the typical effect of
C/C as a function of
soldering time under the worst possible mounting
conditions (horizontal on the PCB, minimum possible pitch)
and with 80
°
C preheating.

RATINGS AND CHARACTERISTICS REFERENCE
CONDITIONS
Unless otherwise specified, all electrical values apply to an
ambient free air temperature of 23
±
1
°
C, an atmospheric
pressure of 86 to 106 kPa and a relative humidity of
50
±
2%.
For reference testing, a conditioning period shall be applied
over 96
±
4 hours by heating the products in a circulating air
oven at the rated temperature and a relative humidity not
exceeding 20%.
