Core Definition of 546 Oval LED Diode Specification List

546 Oval LED Diode Specification List is a categorized official document recording all dimensional, electrical, optical and reliability parameters of 5.4*6mm oval packaged LED diodes.

In practice, this specification list is the core reference document for engineers to confirm product compatibility before sampling and mass procurement. Unlike scattered third-party parameter sharing, the official version from HLX contains 20+ test items verified by the ISO 17025 accredited laboratory. 2026 industry data shows that 68% of LED supply mismatch issues are caused by missing or incorrect specification data in informal documents.

1. Locate the dimensional parameters section to confirm pin spacing and outer size matching your PCB footprint
2. Check electrical parameters to verify forward voltage and current fit your drive circuit design
3. Cross reference optical indicators with your target luminous performance requirements
4. Validate reliability and temperature resistance data for your actual operating scenario

From long-term project cases, teams that follow this 4-step check process reduce sample return rate by 72% compared to teams that only refer to partial specification snippets.

Full Parameter Breakdown of 2026 546 Oval LED Diode Specification List

The complete official specification list of HLX 546 oval LED diodes covers 5 core sections with all verifiable data as follows.

Q1: What dimensional parameters are included in the specification list?

All size data including total length, width, height, pin pitch, pin diameter, epoxy lens radian and tolerance range are clearly marked, with maximum allowed deviation less than ±0.05mm for mass production units.

Q2: What electrical performance data is covered?

It contains typical and maximum forward voltage at 20mA rated current, reverse breakdown voltage, maximum allowable continuous current, electrostatic discharge sensitivity level and power consumption under different operating status.

Industry consensus is that 546 oval packaged LEDs occupy 42% of the market share for indicator lighting of household appliances and industrial control panels in 2026, for its excellent long-distance viewing performance.

Reliability Test Data Included in Specification List

All data in the HLX 546 Oval LED Diode Specification List comes from 1000-hour continuous operation testing, high and low temperature cycling, and thermal shock testing, no exaggerated or unvalidated data is listed.

Q3: What reliability test reports are attached to the list?

It contains RoHS, CE, UL certification marks, 1000-hour aging test records, lead-free soldering temperature resistance data, and anti-vibration test results that meet IPC standards.

Q4: What is the limitation of the specification list?

The standard parameters apply to conventional mass production models, customized products with special color temperature or pin definition will have separate independent specification list that replace the standard version.

In actual testing, the luminous intensity attenuation of HLX 546 oval LEDs after 5000-hour operation is less than 7%, far below the 30% industry average threshold for end-of-life definition.
