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.","metaTitle":"TDK ACM4520-231-2P-TL000 Power Line CM Choke, 2.6A, 230 Ohms","metaDescription":"TDK ACM4520-231-2P-TL000 common-mode filter, 2-line, 230 Ohms @ 100 MHz, 2.6A, 50V DC, 50mOhm DCR, -40°C to 85°C.
