Technical Properties

Designed for Embedded Sensor Shielding

High-Performance Soft Magnetic Alloy

Constructed using a NiFe alloy (48% NiFe), the SMD Shield achieves: High permeability (μr up to 100,000), very low hysteresis (2.8 A/m), Curie temperature of about 450°C, stable saturation flux density (1 Tesla)

Ideal for Planar Current Sensing

The shield is placed directly above or below the sensor, protecting it from parasitic magnetic fields while enabling accurate current measurement.

Flexible Mounting Options

Diagonal leads ensure precise alignment with the magnetic sensor, mountable with glue or available with solderable pins upon request.

Frequently Asked Questions

: Magnetic shielding materials attract and guide magnetic field lines away from sensitive components. By creating a preferred path for the magnetic field, they reduce the field strength within protected regions.
