The 200 mA current rating and 20 VDC voltage rating define the signal path it can clean — think low-current data lines like I²C, SPI, or sensor interfaces running under 20 V. The 600 mOhm max DCR means a 200 mA load drops 120 mV across the filter — budget that into the rail margin if the downstream IC runs near its minimum supply. ## Lifecycle reality — discontinued, no official successor TDK lists the ACM4532-102-3P-T001 as obsolete. For a BOM that already qualifies this footprint, the key cross-reference parameters are the 1812 case size, 3-line configuration, and the 1 kOhm impedance target at 100 MHz. ## Sourcing posture — quoted to order Discontinued by TDK, the ACM4532-102-3P-T001 is available through independent surplus and broker channels.","metaTitle":"TDK ACM4532-102-3P-T001 3-Line EMI Filter, 1 kOhm @ 100 MHz","metaDescription":"TDK ACM4532-102-3P-T001 3-line signal line EMI filter, 1 kOhm impedance at 100 MHz, 200 mA, 20 VDC.
