Emasfalis® LFS Series High μ Shield

The AH series RF Absorber is a near field absorber based on a soft magnetic material that supports a broad range of frequencies. This product is targeted for 100MHz-3GHz, which has a proven track record in mass production for measures against radiation noise inside mobile phones and radiation noise from PCs.

*Affected by application and usage such as noise attenuation, contact surface condition, material, and thickness. ‥

*In general, it is possible to increase the amount of noise attenuation by increasing the thickness of the noise suppression sheet.

LFS Low FRQ Magnetic Shield

AH Series RF Absorber Overview

Overview	MINORU® RF Absorber made of high magnetic permeability soft magnetic material has high flexibility and strong impact absorption characteristics. It is effectively attenuate radiating noise in a wide frequency band from electronic devices and has excellent noise suppression performance especially in the high frequency band.
Structure
Characteristic	High flexibility and high workability for as die cutting. Adhesive layer (optional) facilitates easy assembly. Various magnetic permeability/thickness are available No grounding connection required for flexible design
Application	∗ Suppress for unwanted radiation noise of various devices ∗ Improve reception sensitivity of LTE, Wi-Fi, GPS, etc. * Measures against malfunction due to ESD (electrostatic discharge) * Reduction of radiated noise of various electronic devices (noise from CPU/ASIC etc.) * Reduction of human body electromagnetic wave absorption rate (SAR) of mobile phones ∗ Reduction of EMI (resonance, crosstalk) inside the shield case
Specification
Environment	AH Series is a halogen free product.
