Safety Recognized Ceramic Capacitors Notice
s 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.
s Notice (Rating)
1. Capacitance change of capacitors
(1) In case of SL char.
Capacitance might change a little depending on a
surrounding temperature or an applied voltage.
Please contact us if you use for the strict
constant time circuit.
(2) In case of B/E/F char.
Capacitors have an aging characteristic, whereby
the capacitor continually decreases its
capacitance slightly if the capacitor is left on
5
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 constant time circuit.
Please contact us if you need detailed information.
2. Performance check by equipment
Before using a capacitor, check that there is no
problem in the equipment's performance and the
specifications.
Generally speaking, CLASS 2 (B/E/F char.) ceramic
capacitors have voltage dependence characteristics
and temperature dependence characteristics in
capacitance. So, the capacitance value may change
depending on the operating condition in the equipment.
Therefore, be sure to confirm the apparatus
performance of receiving influence in the capacitance
value change of a capacitor, such as leakage current
and noise suppression characteristic.
Moreover, check the surge-proof ability of a
capacitor in the equipment, if needed, because the
surge voltage may exceed specific value by the
inductance of the circuit.
