The electrification of automobiles is advancing toward autonomous driving, and accordingly noise countermeasures in automobiles become increasingly important. This time, we will introduce an automotive noise suppression filter MHF/MDF series that has unique features as compared to general chip beads.
The MHF series achieves a high impedance in the MF and HF bands ranging from 300 kHz to 30 MHz used in radios, etc., and has an excellent noise suppression effect. Furthermore, the MDF series is a product with excellent DC bias characteristics of impedance so that an excellent noise suppression effect can be obtained even when used in a power supply line.

TDK Corporation (TSE:6762) presents three new B8272* series of compact EPCOS SMT common-mode chokes specially developed for low-voltage applications. They sustain voltages of up to 48 V AC (50/60 Hz) and 80 V DC, and continuous currents between 1.8 A and 19 A at an ambient temperature of 40 °C. The new series cover a range of inductance values between 0.59 mH and 5.6 mH.
