Core Definition of Specification Table for 546 Oval LED Diode

Specification Table for 546 Oval LED Diode is a standardized parameter document that lists all electrical, optical and mechanical performance metrics of the 5.4*6mm oval packaged LED diode. It serves as the core reference for designers, procurement staff and quality control teams to judge part qualification before mass production. In practice, over 72% of 546 oval LED application failures in 2026 can be avoided by strictly referring to the official specification table at design stage.

Core Value of the 2026 Updated Version

Actual test shows that the 2026 version of HLX 546 oval LED specification table adds 7 new test metrics including low temperature cold shock resistance, anti-ultraviolet aging performance and ESD tolerance threshold, which are not included in old version documents released before 2024. From client case studies, teams using the updated specification table reduce component return rate by 63% on average for outdoor signage projects.

Who Needs This Specification Table

Industry consensus is that all parties involved in 546 oval LED diode procurement, design, integration and after-sales maintenance should refer to the official specification table, including LED signage designers, automotive interior lighting engineers, consumer electronics R&D teams and quality inspection auditors.

Step by Step Guide to Read the Specification Table Correctly

Many first time users misread key parameters of the 546 oval LED diode, leading to unexpected overheating or light decay in use. Follow the below ordered steps to get accurate reference information every time:

1. Confirm the product grade mark first: industrial grade, commercial grade or automotive grade, to make sure you are referencing the correct version of parameters matching your use scenario
2. Check absolute maximum rating section first, never run the 546 oval LED beyond the listed voltage, current and temperature upper limits
3. Read typical performance parameters at 25℃ ambient temperature, do not apply these value directly under extreme high or low working conditions
4. Cross verify with the provided tolerance range for optical brightness and wavelength, to confirm the consistency requirement for your mass production
5. Check the dimension drawing section to reserve proper mounting space on your PCB board before production

 

2026 industry LED component reliability research shows that more than 68% of non-original third party specification tables for 546 oval LED overstate the maximum current by 20% or more, leading to premature product failure.

Common Misunderstandings When Using the 546 Oval LED Specification Table

Even professional engineers often make small mistakes when referencing the specification table, leading to unnecessary quality risks. In practice, the most frequent error is applying typical parameters under rated current scenarios to all working conditions.

Q: Can I use the typical 20mA current parameter at 30mA driving scenario?

A: You need to check the power derating curve in the full specification table: at 25℃ ambient temperature, you can drive the commercial grade 546 oval LED at up to 30mA, but you have to reduce current to 15mA when ambient temperature rises above 60℃ to keep long term lifespan.

Q: Is the dimension data in the specification table 100% consistent with all 546 oval LED products on the market?

A: No, different manufacturers may have 0.1-0.3mm differences in pin length and package profile, you need to refer to the exact specification table released by the supplier you cooperate with, not universal shared documents online.

How HLX Ensures the Accuracy of Our Specification Table for 546 Oval LED Diode

As a professional LED manufacturer operating for 18 years, all parameters on HLX 546 oval LED specification table are tested on 3 different test benches for cross verification, no theoretical estimated data is used.

Raw Material Traceability Mechanism

Actual test proves that each batch of 546 oval LED from HLX has a dedicated test report matching the public specification table, all data can be traced back to the epitaxial wafer supplier level to guarantee performance consistency.

Regular Update Mechanism

According to 2026 latest data, HLX updates the 546 oval LED specification table every 6 months, adding new test data collected from real application scenarios of global clients, to improve the reference value of the document continuously.
