Kaschke SMPS Safety Transformers SmarterPower Supply Design

Do you want to outsource your standard or custom made coils and transformers? And you want to do this with a manufacturer with more than 50 years experience, we are gladly to present Kaschke. Kaschke leads the way in the development of standard transformer solutions for SMPS control IC's. All designs meet the necessary safety and performance criteria listed below and are in active production fulfilling many applications.


  • Having the correct and safe construction of an isolating transformer is vital. The transformer provides the main safety isolation barrier between lethal voltage and the end user. If you look at most EN safety standards they go into great detail on the specification of wound components. The qualification and design of safety rated parts are often difficult and time consuming. Kaschke offers you Integrated Safety Margin, at least 3.75kV Primary to Secondary Isolation as Standard. All parts use UL listed materials and are compliant to all EU Safety Standards.

  • Performance

  • With the integration of more control circuitry into the switching IC the most complex part of PSU design is often the transformer rather than the surrounding components. A poorly designed transformer will produce an inefficient and low performing power supply even with the best switching technology. Kaschke provides a lot of solutions. Kaschke Power Ferrite K2006, Low Loss. Optimized for Low Leakage Inductance. Optimized for Low Inter-winding capacity Shield Windings – Improved EMC spec.

  • Reliability

  • Repeatability is the critical component in all PSU designs. Variations in the tolerance or quality can lead to expensive over-design and field failure. The larger the production volume the larger the problem can be. Kaschke's transformer solutions meet all these criteria: They are designed for manufacturing. They are 100% tested. Triple insulated Wire on all parts. Fully Automated Production Process.

  • Optimized Power Factor Correction - a higher efficiency as a result

    Excessive use of electricity and poor efficiencies are no longer accepted which drives you as an engineer toward greater use of power factor correction (PFC). This requires attention to the components employed for power factor correction, particularly the associated inductor.

  • Kaschke Common Mode Chokes, more power in less space

    You're designing a high power application and have some problems with the EMC. You're trying to block the higher-frequency AC while allowing the lower frequency to pass by applying a choke. However there is to less space in the application for this solution.

    The Kaschke common mode filter chokes are designed to meet the EMC regulations even in difficult environments!

  • Kaschke ferrite news - Improved medium permeability material K7000

    Inductive components with ferrite cores generally exhibit excellent properties in the high frequency range. For EMI or wideband applications, medium and high permeability NiZn (Nickel-Zinc) or MnZn (Manganese-Zinc) ferrites are the preferred choice.

    For applications like common-mode chokes, Kaschke has improved the existing K6000 material.
