TDK Expands MLJ1608-G Inductors for 2 GHz Automotive PoC

TDK has expanded its MLJ1608-G multilayer inductor series for automotive power-over-coax circuits, adding a 1.25 µH device with high impedance up to 2 GHz in a compact 1608 package.

Mass production of the MLJ1608WGC1R2MTD25 began in October 2026. The AEC-Q200-compliant device is designed for the wideband filters used to separate power and data in automotive camera PoC connections.

PoC allows both functions to share a single coaxial cable between an automotive camera and electronic control unit. The filter on that connection has to maintain sufficient impedance across a broad frequency range while fitting within increasingly compact camera modules.

Higher Impedance Across Automotive PoC Frequencies

TDK has increased the inductance of the new MLJ1608-G device to 1.25 µH ±20% at 25 MHz. The company compares this with 0.56 µH for its conventional components.

According to TDK, the higher inductance and its material and structural design give the series high impedance across frequencies from 300 MHz to 2 GHz. Between 100 and 700 MHz, TDK specifies impedance around 1.7 to two times higher than its conventional components.

The increased impedance is intended to improve noise suppression within the PoC filter, where several inductors may be used to separate the DC power path from high-speed camera data.

Maintaining that performance across a wide frequency range becomes important as automotive camera systems carry increasing amounts of data while continuing to share the same coaxial connection for power.

1608 Package for Automotive Camera Modules

The MLJ1608WGC1R2MTD25 measures 1.6 × 0.8 × 0.8 mm and uses TDK’s multilayer processing technology to achieve the higher inductance within the compact footprint.

The device has a typical DC resistance of 0.81 Ω and a maximum of 1.20 Ω. Rated current is 350 mA at +105 °C and 200 mA at +125 °C.

TDK is continuing to develop inductors for automotive PoC applications using multilayer, wire-wound and thin-film technologies. The different construction methods give the company options for addressing the impedance requirements found across different parts of wideband PoC filters.

The new MLJ1608-G device is intended primarily for PoC circuits connecting automotive cameras used in advanced driver-assistance systems.
