Product Overview
Electronic Concepts, Inc. 473K 100V polyester film capacitor rated at 0.047 microfarads with ±10% tolerance. Commonly identified by its 473K marking, this value is widely used in passive guitar tone circuits to shape high-frequency roll-off. Polyester film construction offers stable capacitance and predictable response in audio and signal applications. Rated for 100V DC, it is suitable for low-voltage electronics, instrument wiring, filtering, and coupling tasks.
In guitar circuits, 0.047µF is a traditional value for single-coil pickups, producing a deeper high-end cut when the tone control is rolled back. Beyond instruments, this capacitor fits general-purpose filtering and signal coupling where moderate tolerance and film stability are preferred.

Frequently Asked Questions
Will this work in my Strat or Tele style guitar?
Yes. A 0.047µF capacitor is a traditional value for single-coil pickups. It provides a noticeable high-frequency roll-off when paired with a standard tone potentiometer.
What does the “473K” marking mean?
“473” indicates 47,000 picofarads (0.047µF), and “K” indicates ±10% tolerance.
Is 100V too high for guitar use?
No. Guitar circuits operate at very low voltages. A 100V rating simply indicates the maximum DC voltage the capacitor can safely handle.
Can this be used outside of audio projects?
Yes. It is suitable for general filtering and signal coupling in low-voltage DC electronics where a 0.047µF film capacitor is specified.
Some parts quietly shape the sound more than pickups or pedals ever will. This 0.047µF is one of those small decisions that defines how your circuit speaks.
