VLMRY3420-GS18

LED Indication - Discrete Overview

The VLMRY3420-GS18 is a bi-color surface-mount LED from Vishay, housed in a PLCC-4 package. It emits Amber (617 nm) and Yellow (588 nm) light through a colorless, non-diffused round flat lens with a 120-degree viewing angle. The component supports a forward current of 50 mA, with a forward voltage of 2.1 V and a power rating of 130 mW. Light intensity ranges from 355 to 560 mcd. Operating temperatures span -40°C to +100°C.

LED Indication - Discrete Feature Summary

• Dual-chip bi-color configuration providing distinct amber and yellow emission within a single SMD package
• Non-diffused clear lens design for direct visibility and defined beam pattern
• High temperature operational capability suitable for demanding environments

LED Indication - Discrete Applications

• Status indication on industrial control panels
• Signal lights for automotive instrumentation clusters
• Visual alerts in consumer electronic device interfaces

LED Indication - Discrete Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact binning and optical characteristics. Ensure compatibility with standard PLCC-4 footprint dimensions during PCB layout. Confirm RoHS compliance status via the manufacturer's latest datasheet revision. Validate thermal management requirements given the 130 mW power rating and operating temperature range.

LED Indication - Discrete Selection Notes

Select this component when dual-color indication is required in a compact PLCC-4 form factor. Consider the 120-degree viewing angle for visibility requirements. Evaluate the 50 mA forward current limit against circuit drive capabilities. Compare spectral output against ambient lighting conditions to ensure adequate contrast for the intended application environment.

LED Indication - Discrete Part Context

This part belongs to the Vishay VLMx series of multi-color LEDs. It shares the PLCC-4 mechanical outline with other variants in the family but differs in semiconductor materials and color combination. The GS18 suffix indicates specific manufacturing and packaging attributes defined by Vishay Semiconductors.
