The -40°C to 150°C operating range covers the full automotive temperature grade 0 envelope, so it survives cold cranking and hot soak without derating the common-mode attenuation. The 51 µH inductance at 100 kHz gives the low-frequency common-mode attenuation floor; the 2.8 kOhm peak at 10 MHz targets the switching noise band typical of automotive DC-DC converters and CAN/LIN bus lines.","metaTitle":"TDK ACT45B-510-2P-TL003 Common Mode Choke, 2.8 kOhm","metaDescription":"TDK ACT45B-510-2P-TL003 common mode choke, 2.8 kOhms at 10 MHz, 200 mA, 50 VDC, AEC-Q200 qualified.
