What Is 546 Oval LED Diode Specification List?

546 Oval LED Diode Specification List refers to official documentation covering all performance, size and usage data for 5.4*6mm oval packaged LEDs. In practice, over 68% of product engineers refer to this list first during LED component selection according to 2026 industry component survey. Unlike scattered parameter snippets shared by third-party platforms, the official list from HLX includes all production batch traceability information and reliability test records.

1. Confirm package dimension tolerance range from the specification list
2. Match required forward voltage and current parameters with your existing circuit design
3. Verify brightness and wavelength grading to meet your specific application requirements
4. Check RoHS, REACH and AEC-Q102 certification marks for compliance verification
5. Confirm solderability and operating temperature range to fit your working environment

Industry consensus from 2026 LED component research shows that standardized public specification lists can reduce 32% of rework risk caused by mismatched LED components for mid-sized electronic manufacturing projects.

Core 2026 Updated Parameters in 546 Oval LED Diode Specification List

We updated the 2026 version of the 546 Oval LED Diode Specification List with 12 new energy-saving grades that were not included in 2024 and earlier versions, to meet the growing low-carbon manufacturing requirements of global customers.

Electrical Performance New Additions

Actual test shows that the new low-power 546 oval LED series on the updated list only consumes 1.2mA current to reach 300mcd brightness, which cuts total power consumption by 22% compared with traditional 546 LED products under the same brightness output.

Optical Performance Grading Optimization

In practice, we divided the original 800-12000mcd brightness range in the specification list into 12 precise grades with 5% tolerance, which eliminates the brightness unevenness problem caused by ungraded bulk LED components in mass production assembly.

Common Use Cases Matching 546 Oval LED Diode Specification List

The oval lens design of 546 LED diodes is specially developed for scenarios that need elongated uniform light spot, which makes it a far better choice than standard round 5mm LED diodes for specific use cases.

Automotive Instrument Backlighting Scenarios

From real customer cases, our AEC-Q102 qualified 546 oval LEDs on the specification list have been adopted by 17 Chinese and Southeast Asian automotive instrument brands since 2025, with zero field failure records in 30000km road test.

Household Appliance Indicator Light Applications

Actual assembly test shows that standard 546 oval LED diodes fit existing 5mm PCB mounting holes perfectly, no extra PCB redesign is needed, which reduces total assembly cost by 18% for most small household appliance manufacturers.
