- ±2% tolerance (G tolerance code)
- 1 watt power handling capacity
- Metal oxide film element with flameproof silicone coating
- Axial tin-plated copper leads on standard 52 mm taping spacing
- Four-band color sequence: Orange, Black, Red, Red
Applications
- Bleeder and voltage dropping duty in linear power supplies and test bench gear
- Screen and bias circuit repairs in tube amplifiers and vintage audio electronics
- Load and current limiting in industrial control boards and relay drivers
- Custom DIY pedal, synthesizer, and circuit board construction
Frequently Asked Questions
What do the color bands on the body indicate?
The color bands are orange (3), black (0), red (multiplier x100), and red (±2% tolerance), confirming the 3 kΩ value and 2% tolerance rating.
What lead spacing does this tape use?
These components are mounted on 52 mm standard axial tape bandoliers, suitable for automated insertion equipment or manual lead bending.
How are these resistors sold?
Each unit ordered is for one individual resistor cut from the tape strip, so you can purchase the exact count needed for your build without buying an entire reel. More pieces cost less each, and the price-break table on this page shows what each quantity costs. Orders ship for an $8 flat rate, ship free once the order passes $28, and leave our Idaho warehouse the same or next business day.
Nothing steadies a stubborn circuit like a solid 1-watt metal oxide that does its job without complaint. Bend the leads, solder it in, and let the board run clean.
