Kaschke Common Mode Chokes, more power in less space

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!

    Common mode

  • Common mode chokes consists of two coils which are wound on a single core. They are useful for prevention of electromagnetic interference (EMI) and radio frequency interference (RFI) from power supply lines and for prevention of malfunctioning of electronic equipment. Common mode chokes pass differential currents while blocking common mode currents.

  • Higher power in less space

  • Almost all electronics circuits require the use of Common mode chokes to filter out the conducted switching and Radio Frequency noise coming from the power sources such as Switching Mode Power Supplies (SMPS) or other line power outlets. These high frequency noises can affect the performance of other electronic devices, causing potential failures. The rising demand for higher power in less space is driving engineers to design at higher switching frequencies. The advantage is a tighter package, but also brings new challenges for EMC filtering components. The Kaschke common mode filter chokes are designed to meet the EMC regulations even in difficult environments. All chokes have the release according to EN 138100 resp. DIN EN60938-2 (VDE 0565 type 2-1). Besides all thermoplastic materials used are UL94-V0 listed.

  • 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.

  • Planar transformers and inductors design guide

    When designing a switching power supply or DC/DC converter and your willing to reach the best possible efficiency of your application, than it's most common to use a planar transformer instead of an equivalent wire wound transformer design. Standex-Meder manufactures planar transformers for these demanding applications and you can rely on decades of experience. When failure is not an option, designers of critical electronic components rely on the engineers of Standex-Meder and the local support of Heynen BV.

  • 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.
