10. Designing precautions

(1) The current limiting resistor should be placed in the circuit so that is driven within its

rating. Also avoid reverse voltage (over-current) applied instantaneously when ON or OFF.

(2) When pulse driving current is applied, average current consumption should be within the

rating. Also avoid reverse voltage applied when put off.

(3) Recommended soldering pattern

Unit : mm

The above dimensions are not the one which guarantee the performance of mountability.

The use of the above pattern is recommended to use after deep study at your site.

(4) When assembling the circuit board into the finished products, care must be taken to avoid

the component parts from touching other parts.

(5) When using multiple LEDs, it is required to connect a current limiting resistor on

each path which the current flows to the LEDs.

(6) Other

1) This product complies with RoHs directives.

2) When this product is secondarily fabricated such as change in shape,

it is not included in our warranty.

3) The agreement of formal product specification is requied prior to mass production.
