Product catalog summary

Specifications for White LED (Part No. NF2W757HT-F1)

Absolute Maximum Ratings:
The LED has a forward current of 180 mA, a pulse forward current of 240 mA, and an ESD withstand voltage of 8 kV. It allows a reverse current of 85 mA and a power dissipation of 540 mW. The operating and storage temperature ranges are -40 to 100°C, with a junction temperature of 120°C.

Initial Electrical/Optical Characteristics:
At a forward current of 65 mA, the forward voltage is typically 2.72 V. Luminous flux varies by model: R70 - 38.3 lm, R8000 - 35.8 lm, R9050 - 29.8 lm. Chromaticity coordinates are (0.4338, 0.4030), and thermal resistance ranges from 11 to 17 °C/W.

Ranks:
Forward voltage ranges from 2.5 to 3.0 V at 65 mA. Luminous flux ranks from 21.4 to 51.0 lm. Color rendering index varies: R70 - 70, R8000 - 80, R9050 - 90. Color temperature ranges from 2000K to 6500K.

Soldering Recommendations:
Reflow soldering should not exceed 260°C, with a maximum of 10 seconds above 220°C. Hand soldering should not exceed 350°C for more than 3 seconds. Use a nitrogen atmosphere to prevent optical degradation and avoid pressure on the silicone resin.

Packaging:
LEDs are packaged in tape and reel, with 4000 pieces per reel, complying with JIS C 0806 standards. Packaging includes desiccants for moisture protection.

Additional Notes:
LEDs should not be repaired once soldered. Ensure correct polarity and use halogen-free flux.

Forward Current and Temperature Characteristics:
Graphs illustrate forward current and temperature characteristics for different LED models, measured in pulse mode for reference.

Reliability Tests:
Conducted according to JEITA standards, tests include resistance to soldering heat, temperature cycling, and moisture resistance, with no failures reported.

Storage and Handling:
Store LEDs in moisture-proof conditions. Specific storage guidelines are provided, including baking recommendations if moisture exposure occurs.

Usage Directions:
Design circuits to avoid exceeding maximum ratings. Operate LEDs at a constant current and avoid reverse voltages. Precautions for secondary lenses and outdoor applications are included.

Handling Precautions:
Avoid handling LEDs with bare hands. Use appropriate tools and avoid stacking PCBs to prevent damage.

Design Considerations:
Minimize mechanical stress during PCB depaneling and consider the effects of volatile organic compounds.

Electrostatic Discharge (ESD) Protection:
Use grounded equipment and ESD-safe materials. Inspect LEDs for damage by checking forward voltage at low current.

Thermal Management:
Do not exceed the maximum junction temperature. Manage heat effectively by considering PCB thermal resistance and LED density.

Cleaning:
Avoid water or solvents like benzine. Use isopropyl alcohol and verify no adverse effects. Avoid ultrasonic cleaners without verification.

Eye Safety:
Comply with IEC 62471:2006 for photobiological safety. Most LEDs fall under Exempt Group or Risk Group 1.

Miscellaneous:
Nichia provides a one-year warranty under specified conditions, excluding indirect losses. LEDs are not for safety-critical applications and do not comply with IATF 16949. Reverse engineering is prohibited, and Nichia reserves all intellectual property rights.

• Recommended Reflow Soldering Condition(Lead-free Solder) • Recommended Hand Soldering Condition ^ • Recommended Soldering Pad Pattern * This LED is designed to be reflow soldered to a PCB. If dip soldered, Nichia will not guarantee its reliability. * Reflow soldering must not be performed more than twice. Hand soldering must not be performed more than once. * When cooling the LEDs from the peak temperature a gradual cooling slope is recommended; do not cool the LEDs rapidly. * During reflow soldering, the heat and atmosphere in the reflow oven may cause the optical characteristics to degrade....
