Product Overview
Xicon 270-47K-RC metal film through-hole axial resistor, 47k Ohm, 1/8W, ±1% tolerance, 50 PPM/°C temperature coefficient. Sold as a factory bulk bag of 200 pieces. Metal film construction delivers lower noise and better stability over temperature and time compared to carbon film types - useful anywhere resistance accuracy and consistency matter.

Applications
- Inserting through a breadboard or PCB to limit current to an LED string, set bias levels, or build a voltage divider in a hobbyist project
- Replacing drifted or noisy carbon composition resistors in vintage audio amplifiers and tube radios to restore cleaner signal paths
- Setting gain in a precision op-amp stage or sensor interface during prototype development where a stable 47k value is critical
- Stocking a DIY bench supply with pull-up or pull-down resistors for logic circuits and microcontroller projects
- Automotive ECU repair work where a precise through-hole replacement matches the original circuit specification
Frequently Asked Questions
Are these through-hole or surface-mount?
Through-hole axial. Long tinned leads for breadboard or PCB insertion and soldering. Not compatible with surface-mount assembly without adapters.
What is the lot number and are these RoHS compliant?
Lot R7090010, confirmed on the bag label. RoHS compliant, also confirmed on the label.
Is 1/8W enough for audio and general hobby circuits?
For most signal-level and low-power applications - voltage dividers, pull-ups, current limiting, op-amp gain networks - yes. Calculate the actual power dissipation for your circuit (V²/R or I²×R) and confirm it stays well below 0.125W with margin.
How do these compare to carbon film resistors for audio repair?
Metal film resistors produce less electrical noise and hold their value more consistently over temperature and time than carbon film types. For vintage audio signal paths where the original carbon composition resistors have drifted or gone noisy, the 270-series metal film is a common and well-regarded upgrade.
Two hundred of the same value in one bag - that is the kind of thing that turns a parts run into an afternoon of actual building. The 47k is one of those values that shows up everywhere, and having a full bag ready means you never have to stop mid-project to count what you have left.
