TDK offers noise-suppression filters for in-vehicle PoC

TDK Corporation recently announced the launch of its MDF1005 series of noise-suppression filters for in-vehicle PoC, used in applications such as ADAS circuits, BUS lines, telematics units, and more. Mass production has begun this December.

The products in the MDF1005 series offer good DC superimposition characteristics with impedance within the PoC high-frequency band, between 700 MHz and 2.4 GHz. The series is also optimal for the isolation of communication interfaces and noise control.

Also, despite its small size (1.0 mm long and 0.5 mm wide), the products in the series deliver 1000 ohms or greater impedance with the rated current of 400 mA in environments — reaching 125℃.

By using ferrite material with low loss within the high frequency band, the MDF series retains higher impedance at higher frequency when compared to general chip beads, and also controls impedance fluctuation during energization, meeting demands placed on PoC filters while demonstrating noise-controlling effects.

The new filters are qualified in accordance with AEC-Q200. The main applications are for ADAS circuit, BUS line, or telematics unit (e.g. C-V2X, e-call).

Features and benefits include:

Contributes to high-frequency isolation and control of radiation noise (0.7 – 2.4 GHz)
Achieves 1000 ohms (at 900 GHz) or greater with the rated current of 400 mA at 125℃ in the 1005 form
DC superimposition characteristics with good impedance

TDK will continue working to expand the range of impedances to meet the noise-control requirements of customers in various in-vehicle electronic devices.
