EMC Testing and Consulting
EMC Testing and Consulting
—Electromagnetic Compatibility—
Ensuring electromagnetic compatibility (EMC) is an essential requirement for electronic products to comply with relevant regulatory standards and to operate safely alongside other devices simultaneously.
Our company offers comprehensive EMC services, starting from the development phase all the way through to the issuance of the Declaration of Conformity. Our services aim to help our partners’ products smoothly meet the applicable CE or FCC requirements, minimizing the risks associated with market entry.
EMC (Electromagnetic Compatibility) testing ensures that a product does not interfere with other devices and operates reliably itself — a basic requirement for CE marking.
Our measurement services are conducted according to applicable EN standards (e.g., EN 55032, EN 61000 series).
- We also perform development-supporting measurements: pre-tests, troubleshooting, and consulting — assisting successful compliance from the design phase onward.
- Our experienced engineers help design products that meet EMC requirements.

Snap on clamp ferrite core
Snap-on clamp ferrite cores are among the most versatile and user-friendly solutions for suppressing electromagnetic interference (EMI) on cables. Their split-core design allows for quick and tool-free installation directly onto existing cables, making them ideal for both retrofitting and new designs. This flexibility significantly reduces installation time and eliminates the need for disconnecting connectors or rewiring systems.
These ferrites are typically manufactured from Ni-Zn material, optimized for high-frequency noise suppression in the MHz range. They are widely used in power lines, USB cables, communication lines, and industrial control systems, where they help reduce conducted emissions and improve electromagnetic compatibility (EMC) performance.
Snap-on ferrites are especially effective in environments where unpredictable interference may occur, such as office electronics, consumer devices, and industrial equipment. By increasing the impedance of the cable at high frequencies, they attenuate unwanted noise without affecting the desired signal.
Thanks to their wide range of sizes and impedance characteristics, snap-on clamp ferrites can be selected based on cable diameter, frequency range, and required suppression level. They are a cost-effective and reliable solution for meeting EMC compliance requirements.
Flat ferrite
Flat ferrites are compact EMI suppression components designed for applications where space is limited and traditional ferrite cores cannot be easily integrated. Their low-profile geometry makes them particularly suitable for PCB-level applications, flat cables, and compact electronic assemblies.
These ferrites are typically used to suppress high-frequency noise in signal lines and power traces, especially in consumer electronics, automotive modules, and embedded systems. Their design allows for close integration with the circuit, improving overall noise suppression efficiency while minimizing additional space requirements.
Flat ferrites are often made from Ni-Zn materials, providing effective attenuation in the high-frequency range. They are especially useful in applications where maintaining a low profile is critical, such as mobile devices, compact power supplies, and densely packed electronic systems.
In addition to their space-saving benefits, flat ferrites contribute to improved signal integrity and reduced electromagnetic emissions. They are an excellent choice for designers aiming to meet EMC requirements without compromising on size or layout flexibility.
Plastic-encased nanocrystalline foil rings
Plastic-encased nanocrystalline foil rings combine the superior magnetic performance of nanocrystalline materials with robust mechanical protection and safe handling. The plastic enclosure provides reliable electrical insulation, shields the delicate foil structure from mechanical stress, and enhances durability during installation and long-term operation.
These cores are specifically optimized for low-frequency applications, offering high permeability and excellent impedance characteristics from the kHz range, becoming increasingly effective from around 100 kHz and above. Compared to conventional ferrites, nanocrystalline rings deliver significantly higher attenuation at lower frequencies, making them ideal for demanding EMC challenges.
They are widely used in cable assemblies, power electronics, and filtering solutions, where conductors can be routed through the core to achieve strong suppression of both common-mode and differential-mode interference. The toroidal geometry ensures a closed magnetic path, minimizing losses and maximizing efficiency.
The plastic housing is particularly beneficial in industrial, automotive, and high-reliability environments, where mechanical robustness and repeatable assembly are critical. It prevents deformation of the core, reduces handling damage, and supports automated production processes.
Available in a range of sizes and material grades, plastic-encased nanocrystalline rings enable engineers to fine-tune performance across a broad frequency spectrum, making them a preferred solution for EMI filters, common-mode chokes, and high-performance inductive components.
RING TYPE FERRITE
Ring type ferrites (uncoated toroidal cores) are fundamental components in electromagnetic interference suppression and inductive applications. Their closed-loop magnetic structure ensures minimal magnetic leakage and high efficiency, making them ideal for applications requiring stable and predictable performance.
These ferrites are typically used in transformers, inductors, and EMI filters, where wires are wound through the core to create inductive elements. They are suitable for both power and signal applications, depending on the material composition and core size.
Ring ferrites are widely applied in power supplies, telecommunications equipment, and industrial electronics. They provide effective suppression of high-frequency noise while supporting energy storage and signal conditioning functions.
Due to the absence of coating, these cores offer maximum flexibility in design but require careful handling during assembly. They are often chosen in applications where precise winding and optimal magnetic performance are critical.
TUBE TYPE FERRITE
TUBE TYPE FERRITE
Tube type ferrite toroids are designed for applications where cables or conductors need to pass through a cylindrical ferrite structure to achieve EMI suppression. Their tubular shape makes them particularly suitable for inline filtering and cable-based noise reduction solutions.
These ferrites are commonly used in power cables, data lines, and industrial wiring systems, where they help reduce high-frequency interference without requiring complex installation. The design allows for single or multiple turns of the cable, increasing impedance and improving noise attenuation.
Tube ferrites are typically made from high-frequency Ni-Zn materials, ensuring effective performance in the MHz range. They are widely used in applications such as power supplies, communication equipment, and automotive electronics.
Their simple geometry, combined with strong electromagnetic performance, makes them a practical and reliable choice for engineers looking to enhance EMC performance with minimal design complexity.
