Product Overview
Standard 3mm (T-1) red diffused through-hole light emitting diode with integrated base flange. Ideal for panel indicators, status displays, circuit diagnostics, and custom electronic builds.
Key Features
- Lens style: Tinted, diffused red epoxy with base flange
- Package type: 3mm diameter (T-1) radial through-hole
- Lead design: 2-pin through-hole radial wire leads
- Polarity identification: Longer lead anode, shorter lead cathode
- Mounting: Through-hole printed circuit board or solder-cup wiring
Applications
- Soldering power-on or status indicator lamps onto custom circuit boards
- Breadboarding microcontroller indicator pins on Arduino or Raspberry Pi projects
- Replacing burned-out front-panel warning and power lamps on audio gear or test equipment
- Adding illuminated accents or custom lighting to scale models and maker builds
Frequently Asked Questions
How do you identify the polarity of the leads?
Through-hole LEDs use lead length for polarity identification. The longer lead connects to the positive side (anode), while the shorter lead connects to the negative side (cathode).
Can this LED connect straight to a 5V or 12V supply?
No. Like all standard LEDs, this component requires an appropriate series current-limiting resistor matched to your supply voltage to prevent burnout.
Why buy just the exact count needed here instead of a forced surplus lot?
Need more than one? More pieces cost less each - the price-break table on this page shows what each quantity costs.
Buying only the components your project requires avoids spending money on bags of surplus parts that sit unused in a drawer. Shipping is $8 flat rate, free once the order passes $28, and orders leave our Idaho warehouse the same or next business day.
A classic red indicator that gives immediate visual feedback without complication. Plug it into your circuit, wire your dropping resistor, and let it do its job.
