Important:
HT type
In order to improve capacitor mounting, connec-
tions ends are designed with two flats. Thus, tight-
ening torque is only applied on the screw (consult
chart above for torque “S” value).

Capacitance (EIA code)
Capacitance expressed
by 2 significant figures
1st digit: 0 (zero)
2nd and 3rd digits: the 2
significant figures of the
capacitance value.
4th digit:
- for values
³
10pF and
²
990µF: the number of
ZEROS to be added to
the capacitance values
- for values
³
1pF and
²
9.9pF: the figure 9
signifying that the
capacitance value is
to be multiplied by 0.1
Examples: 1000pF: 0102
8.2pF: 0829
Capacitance expressed
by 3 significant figures
1st, 2nd and 3rd digits: the
3 significant figures of the
capacitance value.
4th digit:
- for values > 100pF and
²
999 µF: the number of
ZEROS to be added to
the capacitance value
- for values > 10pF and
< 100pF: the figure 9
signifying that the
capacitance value is
to be multiplied by 0.01.
- for values > 1pF and
²
10pF: the figure 8
signifying that the
capacitance value is

Marking - Packaging - Identification
MARKING
Each part is marked with the following indications:
- Logo
- Reference
- Rated capacitance (EIA code)
- Tolerance on capacitance (EIA code)
- Rated voltage
IDENTIFICATION - TRACEABILITY
On the packaging of all shipped capacitors, you will find a
bar code label (code 39). This label gives systematic infor-
mation on the type of product, part number, lot number,
packing date and quantity.
An example is given below:
Packaging date (YYMMDD)
Lot number
Quantity of parts per packaging
Product and part number reference
This information allows traceability of the entire manufacturing process, from critical raw materials to shipment.
This is extremely useful for any information request, customer complaint or product return.
