DATA SHEET
8. Precautions (continued)
7. Lighting at a low current
A minimum current value of lighting of all dice is 10mA.
When a minimum current is applied, LED dice may look different in their brightness due to
the individual difference of the LED element, and it is not a failed product.
8. Please be aware that this product should not come into contact with any other parts
in assembled status.
9. Drive circuit
- A constant current circuit is recommended as a drive circuit.
And when two or more LED packages are connected, the series connection
between each package is recommended.
- Please design a circuit that prevents any reverse voltage (excess current) from being
applied to this product instantaneously when the circuit is ON or OFF.
10. Heat generation
- As this product is designed with consideration of the heat release property of module,
a heat release design is required to use this product efficiently.
Please ensure that heat generation is not in excess of the absolute maximum rating.
(Refer to 4-1 Performance)
- Factors responsible for an increase in temperature include heat generation attributed to
ambient temperature conditions or power dissipation. Thus, drive conditions should be
taken into consideration, depending on ambient temperature (Ta).
11. Recommended soldering condition (This product is not adaptable to reflow process)
- Manual soldering
- Soldering shall be implemented using a soldering bit of 40W or less with a temperature
350°C or less within 3.5 seconds for one land.
(Recommended condition in a case of lead-free solder condition)
- No external force shall be applied to resin part during soldering.
- Next process of soldering should be carried out after the product has returned to ambient
- For soldering correction
- Regarding soldering correction, above conditions shall be used.
- Contacts number of soldering bit should be within twice for each terminal as a correction.
* Citizen Electronics cannot guarantee if usage exceeds this recommended conditions.
Please use it after sufficient verification is carried out on your own risk if necessary.
