REMARKS

(1)Operating environment

A malfunction in ambulance or vehicle equipment, medical equipment, spacecraft,

nuclear reactors, etc. May cause serious harm to human life or have severe

social ramifications. As such, any products to be used in such equipment may require

higher safety and/or reliability considerations and should be clearly differentiated

from components used in general purpose applications. In this case please consult

Taiyo Yuden Technical Services.

(2)Circuit Design

Applied voltage to products should be less than the maximum input voltage in design

and direct current should not be applied. Please insert resistance more than 10 ohm

in series with MLS.

(3)Installation

*Please do not blow with the compressed air on the diaphragm directly.

*When attaching the product, do not push the terminal more than 2[N] in a vertical

direction and terminal shall not be pushed to other directions.

*Please do not apply tension, pressure or twist to the case of product in the direction

of the diameter.

*Be careful not to deform products or apply distortion stress during installation.

(4)Handling

Please do not touch the diaphragm by finger or others. (when attaching or handling)

(5)Soldering

Soldering of lead wire conditions.

*The lead wire should be soldered to the connection area on the terminal and

do not put the solder iron to the terminal connection area.

*Please the soldering to terminal is under 50W, 250deg C and 5sec.（recommend)

(6)Cleaning

Please avoid cleaning processes. (organic solvent and a water system solvent)

(7)Storage conditions

*Please do not use or keep products in atmosphere of chlorine or sulfide.

*Please keep products under the standard condition.

*Even under ideal storage conditions, products terminal solderability decreases

as time passes, so products should be used within 6 months from the time of delivery.
