MDF1005 Series Noise Suppression Filters

TDK’s MDF1005 series noise suppression filters are designed for in-vehicle PoC applications, such as ADAS circuits, BUS lines, telematics units, and more. The MDF1005 series has 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. Despite its small size of 1.0 mm by 0.5 mm (L x W), the products in the series deliver 1,000 ohms or greater impedance with the rated current of 400 mA in environments reaching +125°C.

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