FHA3C64X-H Datasheet, PDF (13/21 Pages) STANLEY ELECTRIC CO.,LTD. – Blowhole is a type of defect which mostly occurs in direct mounting LED.

Handling precaution
FHA3C64X-H
【 Basic design 】
1.1 Designing for Safety
All LED Lamps are designed to operate without failure in recommended usage conditions. However, all
semiconductor components are prone to unexpected malfunctions and failures. Please take the necessary
precautions to prevent fire, injury and other damage should any malfunction or failure arise.
1.2 Absolute Maximum Rating
Absolute Maximum Ratings are set to prevent LED Lamps from failing due to excess stress (temperature,
current, voltage, etc.). Usage conditions must not exceed the ratings for a moment, nor do reach one items of
Absolute Maximum Rating simultaneously.
1.3 Actual Usage Design
1） _{In order to ensure high reliability from LED lamps, variable factors that arise in actual usage conditions}
should be taken in account for designing.( Derating of TYP., MAX Forward Voltage, etc.)
2） Please insert straight protective resistors into the circuit in order to stabilize LED lamp operation and
also to prevent the device from igniting due to excess current. If LEDs need to be used in a matrix circuit,
a fully understanding of LEDs’ characteristics is required for designing..
3） ^{This LED lamps should be used with current of 2mA or more. If using LED lamps with current over 2}
mA, it might vary considerably in chromaticity, luminous intensity, forward current. So current of 2mA or
more is recommended considering the optimization of product selection and protective resistors.
【 The others 】
1） Once the package is open, please use as soon as possible, as keeping an opened package for a long time
could cause the lead frame to oxidize. For storage, please avoid wetness and humidity, while taking care
to avoid condensation caused by rapid temperature changes.
2） ^{In case of product failures, the lot number on the product package label will be helpful in speeding up}
our response action.
3） Please refrain from looking directly at the light sauce of LED Lamp at high output, as it may harm your vision.
4） ^{Stanley LED Lamps have semiconductor characteristics and are designed to ensure high reliability.}
However, the performance may vary depending on usage conditions
5） ^{Please check the actual performance in the assembly because the Specification Sheets are described for}
single LED.
6） ^{The products are manufactured to be used for ordinary electronic equipment. Please contact our sales}
staff beforehand when exceptional quality and reliability are required, and the failure or malfunction of
the products might directly jeopardize life or health ( such as for airplanes, aerospace, transport
equipment, medical applications, nuclear reactor control systems and so on).
7） If the actual using condition is different from Stanley’s recommended conditions on this specification,
please verify LED lamp’s performance under actual conditions to ensure there is no problem before
actual use.
8） _{The formal specification sheets shall be valid only by exchange of documents signed by both parties.}
9） Any information not listed on this specification shall be separately discussed and determined by both
parties.
