AMOBEADS® and SPIKE KILLER® Noise Suppression Devices

Our AMOBEADS ® and SPIKE KILLER® noise inhibitor parts are amorphous magnetic parts with a high magnetic permeability. They have a stronger noise inhibiting effect than CR snubbers and ferrite beads, making them ideal for high-frequency regulation. Amobeads is particularly useful for situations in which immediate measures against noise are required, as it can be directly placed onto MOSFET and diode leads with no machining of the circuit board required. Our range also includes Spike killer, which has an even stronger noise inhibiting effect than Amobeads.

Magnetic Sheets and LF Antennas

Magnetic sheets made with thin, amorphous magnetic strips for high magnetic permeability. With both high magnetic permeability and low loss in low frequency bands (30kHz-1MHz), these sheets are used for purposes such as radiation noise shields in electronic devices (SS Series) and low-frequency antenna cores (TS Series).

Magnetic Sheets and LF Antennas

Features

  • SS Series for Magnetic Shields
    • Made with SS sheet with high magnetic permeability (relative permeability: 18,000 at 100kHz: Amorphous cobalt type)
    • Higher relative permeability in low frequency bands (30kHz-1MHz) than magnetic powder sheets, achieving an electromagnetic shield effect
    • Lightweight with a thickness of just 63μm (excluding PET release)

  • Antenna Cores for Low Frequency Bands (TS Series)
    • Made from layers of thin amorphous strips (t=0.02mm), enabling slimmer sizes
    • Highly shock-proof - no cracking when dropped or subjected to deforming stress
    • Comparatively low temperature change in response to inductance
    • Can be pressed
    • Enables thinner antennas (0.4mmt), helping to make radio clocks and smart key systems more portable with better designs

Saturable Cores for Mag Amps

Saturable cores for mag amps, a control mechanism for circular compression in switching power output. They are particularly ideal for circuits with a low voltage and high current, as the mag amp method enables more compact sizes, greater efficiency, lower noise, greater reliability and greater precision in power supplies. Our range includes the MT Series, which has outstanding saturability and low loss, and the highly versatile MS series.

FS Series Cores with High Magnetic Permeability

The FS series contains cores with high magnetic permeability. These cores have a particularly high initial permeability in the kHz bands, making them well suited for pulse transformers, noise filters and sensors. Their high magnetic permeability also enables more compact pulse power cores to be produced.

FS Series Cores with High Magnetic Permeability

Features

  • High magnetic permeability enables more compact inductors with higher performance
  • High initial magnetic permeability in the kHz bands
  • Low loss, improving transformer performance
  • Minimal change in permeability in response to changes in magnetic field (strong iso-permeability)
