This white paper explains how industry's first stand-alone active EMI filter ICs reduce choke size by 50% and mitigate common-mode emissions and for single- and three-phase power systems.

Through capacitive amplification, active EMI filter ICs enable engineers to shrink the value of common-mode chokes by up to 80% inductance, resulting in over 50% smaller size compared to purely passive filter solutions.

Active EMI filter ICs help detect and reduce EMI in low-frequency bands, enabling up to 30 dB of additional EMI attenuation at frequencies up to 3 MHz in a broad range of AC/DC systems where common-mode noise is dominant.

Decrease the size, weight and winding resistance of large chokes with TPSF12C1-Q1, active EMI filter IC. This reduces the heat generated and enables extended capacitor lifetimes with increased system reliability.

TPSF12C3-Q1 is able to withstand 5-kV surge immunity specification (IEC 61000-4-5), thus minimizing the need for external protection components. Reduce system size and cost while meeting stringent EMI standards in AC/DC systems.

Read this article to learn how to mitigate EMI, save PCB space and reduce cost with industry's first active EMI filer ICs.

Evaluate the performance of the TPSF12C1-Q1 AEF IC to achieve up to 30 dB of common-mode EMI signature attenuation.

See how the TPSF12C3-Q1 AEF IC supports high-density power supply designs and reduces EMI for three-phase systems.

Mitigating EMI has become more challenging given the large passive filters in power-supply systems. Check out our full portfolio of common-mode active EMI filter ICs and resources to support you on your design journey.
