Mounting
NORMAL USE
The capacitors are designed for mounting on printed-circuit
boards. The capacitors packed in bandoliers are designed
for mounting on printed-circuit boards by means of
automatic insertion machines.
For detailed tape specifications refer to this handbook,
chapter “Packagi ng info rm ati on ”.
SPECIFIC METHOD OF MOUNTING TO WITHSTAND VIBRATION
AND SHOCK
In order to withstand vibration and shock tests, it must be
ensured that the underside of the crimps are in good contact
with the printed-circuit board:
•For pitches ≤15 mm capa citors shall be mech anic ally
fixed by the leads.
•For larger pitches the capacitors shall be mounted in the
same way and the body clamped.
Storage temperature
•Storage temperature: Tstg =−25 to +40 °C with RH
maximum 80% without conden sation.
RATINGS AND C HARACTERISTICS RE FE RENCE
CONDITIONS
Unless otherwise specified, all electrical values apply to an
ambient free air temperat ure 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 temperat ure and a rela tive hum idity not
exceeding 20%.
