Custom Machinery

Planning, design, and implementation of complete automation solutions including:

  • Assembly lines, testing systems (Cognex)

  • Stamping and packaging units

  • Control cabinet construction (Siemens TIA/Step-7)

  • Special solutions for bending and assembly processes

  • Interface integration into existing production lines

Power Supply Systems

Planning and implementation of individual DC supply concepts.
Control cabinet construction and cable routing for:

  • Charge controllers, UPS, and redundancy systems

  • Cable dimensioning up to 300 mm²

  • Core and swivel switching in the DC range

  • Project planning including assembly, testing, and commissioning

In a market of mass-produced goods, we offer custom craftsmanship.

While many providers focus on quantity, we concentrate on one thing: the best possible technical solution – customized for your application. Whether it involves extreme temperature changes, strong vibrations, or tight installation spaces – we develop exactly the component you need. Without compromise.

What makes the difference – at a glance:

“CLASSIC” Capacitors

  • Low temperature range 85°C to 105°C
  • Low vibration resistance

  • Limited variety of shapes
  • Short service life, rapid aging 

  • Unclear origin 

  • Limited soldering process compatibility

“CLASSIC” Capacitors

How can FROLYT capacitors be obtained?2026-04-22T11:02:55+00:00

Answer: Directly from the manufacturer at info@frolyt.de or +49 (0) 3731 571 263 or through listed distributors

How precise are FROLYT shunt resistors?2025-05-20T08:15:21+00:00

We guarantee tight tolerances and low temperature coefficients—ideal for precise current measurements in demanding environments.

Can FROLYT resistors be adapted to specific geometries?2025-05-20T08:14:40+00:00

Definitely. With our production machinery, we can implement custom terminal designs and bending geometries.

Are FROLYT’s shunt resistors suitable for high continuous currents?2025-05-20T08:13:20+00:00

Yes, our shunt resistors are designed for high current loads and are produced with thermal optimization.

Which types of resistors does FROLYT manufacture?2025-05-20T08:12:14+00:00

We manufacture wire and strip shunt resistors for current measurement, power control, and industrial applications.

Does FROLYT also offer samples or small series?2025-05-20T07:55:05+00:00

Yes. We also manufacture prototypes, pre-series runs and custom solutions in small quantities – with short lead times.

What is the service life of FROLYT capacitors?2025-05-20T07:54:00+00:00

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.

Which capacitor form factors does FROLYT manufacture?2025-05-20T07:52:35+00:00

Axial, radial, SMD, snap-in, press-fit and can types – each individually designed for the application.

Can FROLYT manufacture capacitors for high temperatures and vibration loads?2025-05-20T07:51:09+00:00

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.

“Switch on-switch off-throw away” is not a sustainable concept – quality is.

There is a demand for long-lasting top-tier products that make ecological and economic sense. This is exactly what FROLYT stands for – and exactly why more production is needed here in this country. Because true diversity is not created by a few large Far Eastern providers – but by reliable, specialized partners with a sense of responsibility.
