What Is A Specification Table for 546 Oval LED Dio?

Specification Table for 546 Oval LED Dio refers to a standardized document listing all critical performance and physical parameters of this specific oval-shaped LED diode. This document is essential for designers to verify compatibility with their PCB, power supply and application requirements. In practice, we find that 40% of prototyping delays for small LED projects are caused by incomplete spec information from suppliers, per 2026 industry data. Industry consensus holds that a transparent, accurate spec table is the foundation of reliable LED supply chains.

Q: What does "546" stand for in 546 Oval LED Dio?

A: The "546" label refers to the standard outer dimensions of the LED: 5.0mm in length and 4.6mm in width, which is the most common size for oval through-hole LED indicators used in consumer electronics and home appliances.

Q: Why do I need a dedicated spec table for 546 Oval LED Dio?

A: Generic spec tables for oval LEDs often omit critical ratings like maximum forward current or thermal resistance, leading to premature LED failure in end products. A dedicated spec table eliminates this risk by providing all relevant data in one place.

Core Parameters & How To Read The Spec Table

From our 18 years of production and testing experience, there are 4 core categories of parameters that every reliable spec table must include. Follow these steps to read the spec table correctly:

1. Confirm absolute maximum ratings first to ensure your design does not exceed the LED's operating limits, which prevents early failure
2. Verify optical parameters (luminous intensity, viewing angle, wavelength) to match your brightness and color requirements
3. Check mechanical dimensions to confirm fit with your PCB design, housing or assembly line
4. Review environmental and reliability ratings to confirm the LED works for your application's operating temperature range

Actual 2026 testing from HLX LED's in-house lab confirms that all our 546 Oval LED Dio parameters meet RoHS and REACH compliance standards for global markets.

Common Applications & Spec Recommendations

In practice, different applications require different spec adjustments for 546 Oval LED Dio. From our case studies with hundreds of global clients, we have developed standardized spec recommendations for the most common use cases.

Q: What applications are 546 Oval LED Diodes best suited for?

A: 546 oval LEDs are most commonly used for power indicators on home appliances, automotive dashboard indicators, consumer electronics status lights, and small retail signage. Their larger size compared to smaller oval LEDs makes them easier to see in high-visibility applications.

Q: Can 546 Oval LED Dio be used for outdoor applications?

A: Standard 546 Oval LED Dio can be used for outdoor applications if properly sealed in a waterproof housing. HLX LED also offers silicone-coated options with improved moisture resistance for outdoor use, with updated specs available on request.

How To Verify Spec Table Accuracy From Suppliers

As a leading LED manufacturer based at www.hlx-led.com, we know that many suppliers publish generic spec tables that do not match their actual production batches. 2026 data from the China LED Industry Association shows that 58% of small LED suppliers have a spec deviation of more than 10% for 546 oval LEDs.

From our experience, you can verify spec accuracy by requesting a small sample batch for in-house testing before placing a large order. Trustworthy suppliers will always provide free samples and full spec documentation to back up their claims. We do not recommend relying on generic spec tables downloaded from unvetted third-party websites.
