This LED is manufactured with environmental and regulatory compliance as a priority. It is a Pb-free (lead-free) product, aligning with global restrictions on hazardous substances. The product itself remains within the compliant version of the RoHS (Restriction of Hazardous Substances) directive. It also complies with the EU REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulation. Furthermore, it is classified as Halogen Free, with strict limits on bromine (Br < 900 ppm), chlorine (Cl < 900 ppm), and their combined total (Br+Cl < 1500 ppm). These specifications make it suitable for markets with stringent environmental regulations.

Ana ƙididdige ƙimar resistor ta amfani da Dokar Ohm: R = (V_supply - VF_LED) / I_desired.

5.2 Storage and Moisture Sensitivity

The LEDs are packaged in a moisture-resistant barrier bag with desiccant to prevent absorption of atmospheric moisture.

• Before Opening: Store at ≤30°C and ≤90% Relative Humidity (RH).
• After Opening: The "floor life" is 72 hours under conditions of ≤30°C and ≤60% RH. If not used within this time, unused parts must be resealed in a moisture-proof package with fresh desiccant.
• Baking: If the desiccant indicator shows saturation or the floor life is exceeded, the components must be baked at 60±5°C for 24 hours before use to drive out moisture and prevent "popcorning" during reflow soldering.

5.3 Reflow Soldering Profile (Pb-free)

A specific temperature profile is required for Pb-free solder alloys:

• Pre-heating: Ramp from ambient to 150-200°C over 60-120 seconds (max ramp rate 3°C/sec).
• Soak/Reflow: Time above liquidus (217°C): 60-150 seconds. Peak temperature must not exceed 260°C, and time above 255°C must not exceed 30 seconds. The component should be at peak temperature for a maximum of 10 seconds.
• Cooling: Maximum cool-down rate of 6°C/sec.
• Important: Reflow soldering should not be performed more than two times on the same board/component.

5.4 Hand Soldering and Rework

If hand soldering is necessary, extreme care is required. Use a soldering iron with a tip temperature ≤350°C and a power rating ≤25W. Contact time per terminal must be ≤3 seconds. Allow a cooling interval of at least 2 seconds between soldering each terminal. Avoid applying mechanical stress to the component during heating. Rework is strongly discouraged. If absolutely unavoidable, use a specialized double-head soldering iron to simultaneously heat both terminals and lift the component evenly to avoid damaging the solder pads or the LED itself.

6. Packaging and Ordering Information

6.1 Standard Packaging

LEDs are supplied on embossed carrier tape sealed within a moisture-proof bag. The tape width is 12mm, wound on a standard 7-inch (178mm) diameter reel. Each reel contains 1000 pieces. Detailed dimensions for the carrier tape pockets and the reel are provided to ensure compatibility with automated assembly equipment.

6.2 Label Explanation

The packaging labels include several codes for traceability and binning:

• P/N: Product Number (95-21SYGC/S530-E3/TR9).
• LOT No: Manufacturing Lot Number for traceability.
• QTY: Packing Quantity (e.g., 1000).
• CAT: Luminous Intensity Rank (Binning for brightness).
• HUE: Dominant Wavelength Rank (Binning for color).
• REF: Forward Voltage Rank (Binning for VF).

8. Technical Comparison and Differentiation

Compared to older through-hole LED technologies, this SMD LED offers superior size, weight, and assembly advantages. Within the SMD yellow-green LED segment, its key differentiators are its specific combination of a relatively high luminous intensity (630mcd) at a low forward current (20mA), a standard 2.0V forward voltage compatible with many logic-level voltages, and its compliance with modern environmental standards (RoHS, REACH, Halogen-Free). The AlGaInP chip technology provides good efficiency and color stability for the yellow-green spectrum.

12. Trends na Fasaha da Mahallin

The component described represents a mature and widely adopted technology within the broader LED industry. Key ongoing trends influencing such components include:

• Further Miniaturization: While the 95-21 package is small, even smaller chip-scale package (CSP) LEDs are emerging for ultra-compact designs.
• Increased Efficiency: Continuous improvements in epitaxial growth and chip design lead to higher luminous efficacy (more light output per electrical watt), allowing for lower drive currents and reduced power consumption.
• Enhanced Reliability and Lifetime: Ingineering za uboreshaji wa vifaa vya ufungaji na usimamizi wa joto zinapanua maisha ya uendeshaji, na kufanya LEDs zifae kwa matumizi muhimu zaidi.
• Ujumuishaji: Mienendo ni pamoja na kujumuisha chips nyingi za LED (RGB) katika kifurushi kimoja au kuchanganya LED na IC ya kiendeshi kwa muundo rahisi wa mfumo.
• Uzingatiaji Mkali: Kanuni za kimazingira kama RoHS na REACH zinaendelea kubadilika, na kusukuma wazalishi kuelekea seti safi zaidi za vifaa na michakato.

Karatasi hii ya data inaonyesha sehemu ya kuaminika, iliyosanifishwa ambayo iko kwenye makutano ya mienendo hii, na inatoa usawa wa utendaji, ukubwa, gharama, na uzingatiaji kwa anuwai kubwa ya bidhaa za elektroniki.
