THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE. THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT

When soldering radial leaded ceramic capacitors with a soldering iron, it should be performed under the following conditions

and should not exceed:

• Maximum temperature of iron-tip: 400 °C

• Maximum soldering iron wattage: 50 W

• Maximum soldering time: 3.5 s

Failure to follow the above cautions may result, in worst case, in short circuit or cause fuming or thermo-mechanical damage

when the product is used.

Leaded ceramic capacitors are not designed for reflow process or dipping the body into a solder melt.

CLEANING

The components should be cleaned immediately following the soldering operation with vapor degreasers.

CLEANING (ULTRASONIC CLEANING)

To perform ultrasonic cleaning, observe the following conditions:

• Maximum rinse bath capacity output: 20 W/liter

• Maximum rinsing time: 300 s

• Do not vibrate the PCB/PWB directly

• Excessive ultrasonic cleaning may lead to mechanical damage

SOLVENT RESISTANCE

The coating and marking of the capacitors are resistant to the following test method:

IEC 60068-2-45 (method XA)

MOUNTING

We do not recommend modifying the lead terminals, e.g. bending or cropping. This action could break the coating or crack the

ceramic insert. In order to avoid such failures we are offering different lead wire designs (e.g. straight, inline, inside crimp,

outside crimp etc.) If however, the lead must be modified in any way, we recommend support of the lead with a clamping fixture

next to the coating. If a defined product stop is required for mounting on a PCB, a mechanically formed product stop or a

mounting tool should be used.

OPERATING VOLTAGE

In case the voltage is applied to the circuit, starting as well as stopping, may generate irregular voltage for a transit period

because of resonance or switching. Be sure to use a capacitor with a rated voltage range that includes these irregular voltages.

OPERATING TEMPERATURE AND SELF-GENERATED HEAT

Keep the surface temperature of a capacitor below the upper limit of its rated operating temperature range. Be sure to take into

account the heat generated by the capacitor itself. When the capacitor is used in a high frequency, pulse, or similar application,

it may have self-generated heat due to dielectric dissipation.

Temperature increase due to self-generated heating should not exceed 20 °C while operating at an atmosphere temperature of

25 °C.

When measuring, the surface temperature, make sure that the capacitor is not affected by radiant, conductive and convective

heat by its surroundings. Excessive heat may lead to thermo-mechanical deterioration of the capacitor's characteristics and

reliability.
