Notice for General Usage -MHz Chip Type-

Continued from the preceding page.

Please mount component on a circuit board by reflow

soldering. Flow soldering is not acceptable.

1. Soldering

Conformal coating or washing of the component is not

acceptable, because it is not hermetically sealed.

Please contact us if you need a washable component.

2. Washing / Coating

(1) Reflow soldering

Recommendable Flux and Solder

If compelled to mount the component by using soldering

iron, please do not directly touch the component with the

soldering iron. The component terminals or electrical

characteristics may be damaged if excessive thermal

stress is applied.

(2) Soldering with Iron

Do not reuse components removed from a circuit board

after soldering.

(3) Other

The component is recommended with placement

machines that employ optical placement capabilities. The

component may be damaged by excessive mechanical

force. Please make sure that you have evaluated by

using placement machines before going into mass

production. Do not use placement machines that utilize

mechanical positioning. Please contact Murata for details

beforehand.
