What Is the Official 546 Oval LED Diode Specification List

546 Oval LED Diode Specification List refers to standardized test-verified performance and dimension parameters for 5*4.6mm oval LED diodes. Developed by HLX R&D teams following IPC and IEC optoelectronic component standards, this list covers all mandatory indicators required for mass production adoption. In practice, 78% of LED product development delays are caused by missing or inaccurate spec data for small package diodes, per 2026 global optoelectronics industry survey. You can follow 3 core steps to validate if a 546 oval LED spec list is reliable:

1. Confirm all parameters are tested under standard 25℃ room temperature, 20mA forward current baseline condition
2. Check if the spec list includes both typical and maximum allowable values instead of only nominal marketing data
3. Verify the data is attached with corresponding test equipment calibration certificates issued within the last 12 months

Industry consensus is that certified 546 Oval LED Diode Specification List can reduce post-sales failure rate of LED signage products by up to 47% compared with unvalidated generic parameter sheets.

Core Parameters Breakdown for 2026 546 Oval LED Diode Specification List

Q1: What are the easily ignored non-electrical parameters in the spec list?

In practice, the epoxy resin UV resistance grade and lead tin plating thickness are two easily missed parameters that directly affect wave soldering yield and outdoor service life. HLX 2026 production data shows that 546 oval diodes with 8um+ matte tin plating reduce cold joint rate by 42% compared with 3um tin plating variants.

Q2: Why 546 oval package has different spec requirements from common 5mm round LED?

From optical testing experience, the oval package offers 30% higher horizontal light utilization, so the 546 Oval LED Diode Specification List must include directional horizontal luminous intensity values instead of total luminous flux data to support accurate signage visibility design.

Practical Selection Guide Using 546 Oval LED Diode Specification List

Q3: How to select suitable spec combinations for outdoor LED message boards?

From case studies with 300+ HLX signage clients, select variants with IP65 lead seal rating and VF tolerance within ±0.1V per the spec list to avoid inconsistent brightness under high temperature 60℃ outdoor working conditions in summer.

Q4: Can the 546 Oval LED Diode Specification List be adjusted for custom needs?

HLX Electronics supports minor parameter customization including color wavelength tuning, pin length adjustment and viewing angle modification, with a 7-day lead time for updated spec validation according to our 2026 customer service SOP for bulk orders over 50,000 units.

Common Misuses of 546 Oval LED Diode Specification List

Q5: What risks come with using uncertified third-party spec lists?

2026 global optoelectronics research shows that 32% of low-quality copied spec lists omit reverse voltage parameters, which leads to 2x higher failure rate during standard ESD (electrostatic discharge) testing in mass production.

Q6: Do I need to refer to separate spec lists for different production batches?

In practice, HLX provides batch-specific spec supplementary sheets for each shipment, and the parameter variation across different manufacturing batches is controlled under 2%, so no extra re-testing is required for most standard applications.
