EMC/EMI Calculators

RF Shielding

Calculate electromagnetic shielding effectiveness of conductive enclosures

Ferrite Bead

Calculate ferrite bead filter effectiveness, impedance at frequency, and insertion loss for EMI suppression

LC EMI Filter

Design an LC low-pass EMI filter for conducted emissions suppression — calculate inductance, capacitance, filter order, and attenuation at the stop band.

ESD TVS Diode

Calculate TVS diode clamping voltage, breakdown voltage, peak pulse current, and power rating for ESD protection circuit design.
