That impedance peak sits right where conducted EMI from switching regulators and digital clocks couples onto the DC bus — the filter presents a high series impedance to common-mode noise while letting the differential power current pass through with minimal loss. The 50 V DC rating covers most board-level power buses including 48 V telecom rails, so the voltage margin is not the limiting factor here — the 2 A current ceiling is the spec that governs the fit.","metaTitle":"TDK ACM4520-901-2P-TL000 Power Line Common Mode Filter","metaDescription":"TDK ACM4520-901-2P-TL000 common mode filter, 900 Ohms @ 100 MHz, 2 A, 50 VDC, 60 mOhm DCR, SMT.
