Aluminum Electrolytic Capacitors
Over 70 Years: Development & Manufacturing at the Freiberg Location
Electrolytic capacitors are critical components in modern electronic systems and must meet the highest requirements for reliability and service life. As an experienced manufacturer, Frolyt has been developing and producing aluminum electrolytic capacitors at its Freiberg, Germany location for over 70 years.
Our capacitors are tested under real-world conditions and deliver high temperature resistance, long service life, and stable performance even under continuous load. Long-term tests of up to 25,000 hours at 105°C and high-temperature testing up to 150°C demonstrate the quality of our products.
Whether standard solution or custom development – we offer a broad portfolio of electrolytic capacitors for a wide range of applications. Benefit from our experience, technical expertise, and reliable components for demanding applications.
Our capacitors don’t just perform in theory – they perform in testing.
Long-term tests under real-world conditions demonstrate the high reliability and service life of our aluminum electrolytic capacitors. We focus on scenarios where other components frequently fail – such as heat, continuous load, or confined installation spaces.
Case Study: LED Service Life Secured by Frolyt Capacitors
“A service life of 100,000 hours is no problem for LEDs – but capacitors often fail earlier.”
Through optimized system design and specialized materials, Frolyt capacitors achieve service lives that reliably withstand even continuous operation in LED drivers.
Result: No dry-out, no premature failures – even under thermally demanding conditions.
Continuous Voltage Testing at 105°C – 25,000 h Verified
Our aluminum electrolytic capacitors with Ø10.0 × 21.0 mm achieve an operating life of 25,000 hours under continuous voltage at 105°C – a peak value in this package size.
High-Temperature Testing: 2,000 h at 150°C Passed
Both radial and axial designs with 25 V rated voltage successfully passed 2,000 hours of continuous testing at 150°C ambient temperature.
All results are regularly documented and updated.

What Our Customers Frequently Want to Know
Answer: Directly from the manufacturer at info@frolyt.de or +49 (0) 3731 571 263 or through listed distributors
Yes. We also manufacture prototypes, pre-series runs and custom solutions in small quantities – with short lead times.
Depending on the type and application, up to 40,000 h at 105 °C – with optimal system integration, even up to 20 years in real-world operation.
Axial, radial, SMD, snap-in, press-fit and can types – each individually designed for the application.
Yes. Our components are temperature-resistant up to 150 °C and vibration-resistant up to 30 g on three levels – ideal for automotive and industrial applications.
