It is designed for power line filtering and carries an AEC-Q200 qualification, making it suitable for automotive electronic modules that must pass conducted EMI limits on the battery or ignition lines. Rated at 1 A continuous current with a maximum DC resistance of 80 mOhm, this choke presents 1.4 kOhms of common-mode impedance at 100 MHz. An engine control unit or transmission controller sitting near the engine block at 105°C ambient still has margin before the ferrite core saturates thermally. ## NRND — plan last-time-buy or qualify a replacement This means the part remains available for existing production BOMs but is not intended for new design-ins. For procurement teams managing an active BOM, this NRND status signals a need to evaluate last-time-buy quantities or identify a pin-compatible alternative from the same ACM-V series family.","metaTitle":"TDK ACM4520V-142-2P-T00 Power Line CM Choke, 1 A, AEC-Q200","metaDescription":"TDK ACM4520V-142-2P-T00 common-mode choke, 1.4 kOhms @ 100 MHz, 1 A, 50 VDC, AEC-Q200.
