Performance & Characteristics
Electrolytic capacitors like this use an aluminium oxide dielectric layer, allowing high capacitance values in a relatively small package—ideal for power supply filtering and signal coupling in audio circuits.
Typical 250µF / 75V axial capacitors are designed for:
- General-purpose use
- Operating temperatures up to 85°C
- Lifetimes in the range of hundreds to thousands of hours depending on load conditions
Richey capacitors are commonly used in industrial and consumer electronics and are known for stable performance within standard operating tolerances, with capacitance variation typically within ±20% over life.
Applications
- Tube amplifier power supply filtering
- Cathode bypass capacitors
- Vintage amp restoration
- General electronics repair
- Audio circuits
Notes
- Polarised capacitor — observe correct polarity during installation
- Suitable replacement for vintage axial electrolytics of similar rating
- Voltage rating can safely exceed circuit requirements, but not be lower
