Overview
The Sprague CE44C100R is a single-section aluminum electrolytic capacitor rated at 10µF and 450 volts DC. This vintage component was manufactured by Sprague Electric Company and is widely sought for restoration of classic audio amplifiers, vintage radio equipment, and industrial electronics. The Sprague CE44C100R delivers stable performance in high-voltage filtering applications and is a recognized standard in equipment from the mid-20th century.
Key Features
- Capacitance: 10µF nominal
- Voltage rating: 450V DC maximum
- Single-section aluminum electrolytic construction
- Axial lead termination (typical for vintage Sprague Atom series)
- Suitable for vintage audio, radio, and industrial equipment restoration
- Legacy component with proven reliability in high-voltage applications
Technical Specifications
The Sprague CE44C100R meets historical specifications for mid-century electrolytic capacitors. Typical performance parameters include temperature stability across standard operating ranges and low ESR characteristics appropriate for filtering and signal coupling in audio circuits.

- Laboratory and test equipment power conditioning
- Replacement in vintage synthesizers and electronic musical instruments
Compatibility & Replacements
Compatible With
- Vintage tube amplifier designs (Fender, Marshall, Ampeg, and similar audio equipment)
- Classic audio preamps and power amplifiers
- Mid-century industrial control equipment
- Antique radio receivers and transmitters
- Laboratory power supplies rated 450V or lower
Replaces / Drop-In Replacement For
The Sprague CE44C100R can serve as a direct replacement in any circuit originally specified for a 10µF 450V aluminum electrolytic capacitor. Verify mounting orientation and lead configuration before installation. Modern equivalent capacitors (such as CE Manufacturing multi-section types) may substitute if voltage and capacitance ratings are matched, though vintage originals are preferred for restoration authenticity.
Works With
- Vintage amplifier recapping kits and restoration harnesses
- Tube amp power supplies and filter banks
- Standard soldering and lead-dress techniques for vintage equipment
- Equivalent vintage Sprague and competitor capacitors (Mallory, Illinois, Sangamo)
