• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please review our product specifications or consult the approval sheet for product specifications before ordering.

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) For SL char.

Capacitance might change a little depending on a

surrounding temperature or an applied voltage.

Please contact us if you use a strict constant time

circuit.

(2) For B/E/F char.

Capacitors 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. Therefore,

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.
