Product details

What the 230-ohm impedance means on a 2.6 A rail

The ACM4520-231-2P-TL000 is a two-line common-mode choke from TDK's ACM series, built to knock down conducted noise on a DC power bus before it radiates or couples into sensitive circuitry. The headline number is 230 Ohms at 100 MHz — that is the common-mode impedance it presents to noise riding on both lines in phase.

Board-fit and thermal envelope

No derating curve is published here, but the 85°C ceiling is the standard industrial temperature grade; if the ambient near the choke runs hotter, the current rating should be backed off per the manufacturer's derating.
