!Note
• Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering.
■ !Caution (Soldering and Mounting)
1. Vibration and impact
Do not expose a capacitor or its leads to excessive
shock or vibration during use.
2. Soldering
When soldering this product to a PCB/PWB, do not
exceed the solder heat resistance specification of
the capacitor. Subjecting this product to excessive
heating could melt the internal junction solder and
may result in thermal shocks that can crack the
ceramic element.
When soldering capacitor with a soldering iron, it
should be performed in following conditions.
Temperature of iron-tip: 400 degrees C. max.
Soldering iron wattage: 50W max.
Soldering time: 3.5 sec. max.
FAILURE TO FOLLOW THE ABOVE CAUTIONS MAY
RESULT, WORST CASE, IN A SHORT CIRCUIT
AND CAUSE FUMING OR PARTIAL DISPERSION
WHEN THE PRODUCT IS USED.
■ !Caution (Handling)
Vibration and impact
Do not expose a capacitor or its leads to excessive
shock or vibration during use.
FAILURE TO FOLLOW THE ABOVE CAUTIONS MAY
RESULT, WORST CASE, IN A SHORT CIRCUIT
AND CAUSE FUMING OR PARTIAL DISPERSION
WHEN THE PRODUCT IS USED.
■ Notice (Soldering and Mounting)
Cleaning (ultrasonic cleaning)
To perform ultrasonic cleaning, observe the following
conditions. Rinse bath capacity : Output of 20 watts
per liter or less.
Rinsing time : 5 min maximum.
Do not vibrate the PCB/PWB directly.
Excessive ultrasonic cleaning may lead to fatigue
destruction of the lead wires.
■ Notice (Rating)
Capacitance change of capacitor
1. Class 1 capacitors
Capacitance might change a little depending on the
surrounding temperature or an applied voltage.
Please contact us if you intend to use this product
in a strict time constant circuit.
2. Class 2 and 3 capacitors
Class 2 and 3 capacitors with temperature
characteristics B, E and F have an aging
characteristic, whereby the capacitor continually
decreases its capacitance slightly if the
capacitor is left on for a long time. Moreover,
capacitance might change greatly depending on the
surrounding temperature or an applied voltage.
So, it is not likely to be suitable for use in a
time constant circuit. Please contact us if you
need detailed information.
