Water Clear Subminiature Axial Ultra Yellow brightest led chip 1.80mm Round

Features:

• 2.15×2.40mm with 1.80mm lens.
• Small double-end package.
• EIA Std. package.
• Mono-color type.
• High reliability.
• Low forward voltage.
• Compatible with automatic placement equipment.
• The product itself will remain within RoHS compliant version.

Descriptions:

• The R18 SMD taping is much smaller than leaded components. Thus enable smaller board size. Higher packing density. Reduced storage space and finally smaller equipment to be obtained.
• Besides, light weight makes them ideal for miniature applications.
• Furthermore by automation assembly machines the accuracy is anticipated.

Applications:

• Small indicator for indoor applications.
• Flat backlight for LCD, switches and symbols.
• Indicator and backlight in office equipment.
• Indicator and backlight for battery driven equipment.
• Indicator and backlight for audio and video equipment.
• Automotive: Backlighting in dashboards and switches.
• Telecommunication: Indicator and backlighting in telephone and fax.

Package Dimension:

Notes:

• All dimensions are in millimeters (inches).
• Tolerance is ± 0.10mm (.004") unless otherwise specified.
• Specifications are subject to change without notice.

Absolute Maximum Ratings at Ta=25℃

Electrical Optical Characteristics at Ta=25℃

Notes:

• Luminous Intensity Measurement allowance is ± 10%.
• θ_1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
• The dominant wavelength (λd) is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.

Reliability Test Items And Conditions:

The reliability of products shall be satisfied with items listed below:

Confidence level: 90%.

LTPD: 10%.

1) Test Items and Results:

2) Criteria for Judging the Damage:

*) F.V.: First Value.

Please read the following notes before using the product:

1. Over-current-proof

Customer must apply resistors for protection, otherwise slight voltage shift will cause big current change (Burn out will happen).

2. Storage

2.1 Do not open moisture proof bag before the products are ready to use.

2.2 Before opening the package, the LEDs should be kept at 30℃ or less and 90%RH or less.

2.3 The LEDs should be used within a year.

2.4 After opening the package, the LEDs should be kept at 30℃ or less and 70%RH or less.

2.5 The LEDs should be used within 168 hours (7 days) after opening the package.

2.6 If the moisture adsorbent material (silica gel) has fabled away or the LEDs have exceeded the storage time, baking treatment should be performed using the following conditions. Baking treatment: 60±5℃ for 24 hours.

3. Soldering Condition

3.1 Pb-free solder temperature profile.

3.2 Reflow soldering should not be done more than two times.

3.3 When soldering, do not put stress on the LEDs during heating.

3.4 After soldering, do not warp the circuit board.

4. Soldering Iron

Each terminal is to go to the tip of soldering iron temperature less than 260℃ for 5 seconds within once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder.

5. Repairing

Repair should not be done after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.

6. Caution in ESD

Static Electricity and surge damages the LED. It is recommended to use a wrist band or anti-electrostatic glove when handling the LED. All devices, equipment and machinery must be properly grounded.
