Product Overview
Panasonic LNG901CFBW delivers true blue illumination from a discrete 5 mm (T-1 3/4) radial through-hole package, centered at a 468 nm peak wavelength. Built with a clear, colorless epoxy dome lens, it produces a typical luminous intensity of 650 mcd at a standard 20 mA operating current.
Key Features
- 468 nm peak emission wavelength for distinct blue illumination
- 650 mcd typical luminous intensity (390 mcd minimum) at 20 mA
- 3.5 V typical forward voltage with 4.0 V maximum at 20 mA
- 30 mA maximum continuous forward current
- Clear colorless transparent epoxy 5 mm (T-1 3/4) domed package
- 2-pin radial through-hole leads with crimped standoffs on 2.54 mm (0.100 in) spacing
Applications
- Direct replacement for obsolete Panasonic indicator LEDs in industrial control boards and legacy test instruments
- Front-panel status and power indication in custom audio gear, modular synthesizers, and breadboard prototypes
- Restoration of late-1990s and early-2000s electronics requiring period-accurate optical characteristics
Frequently Asked Questions
What is the forward voltage drop and recommended drive current?
The LED operates typically at 3.5 V with a nominal current of 20 mA. Maximum continuous forward current is rated at 30 mA.
What is the lead pitch for PCB mounting?
The leads feature formed standoffs spaced at the industry-standard 2.54 mm (0.100 in) pitch, fitting perfboards, breadboards, and standard through-hole circuit boards. Order more and each piece costs less - the price-break table on this page spells it out.
Before true-blue LEDs became everyday commodities, a solid 468 nm emitter was a standout on any instrument panel. Drop it into an original restoration or custom build to get that crisp, classic indicator tone.
