An inner conductor is encircled by a concentric conducting shield, and the two are separated by a dielectric (insulating substance); many coaxial cables also have a protective outer sheath or jacket.
Coaxial cable, commonly known as coax, is a form of electrical cable. A passive electrical component known as an inductor stores energy as a magnetic field.
The Global Coaxial Inductors market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
To address changing automotive PoC demands, TDK has introduced more sophisticated multilayer inductors. The launch of the new MLJ1608WG Series of multilayer inductors has been announced by TDK Corporation.
These small parts are intended for Power over Coax (PoC) installations in automobiles.The maximum impedance of the inductors of the MLJ1608WG Series is 2500.
Additionally, they maintain impedance levels of 1000 from 300 MHz to 2 GHz. The MLJ1608WG Series offers far less current variation than typical multilayer inductors, whose impedance characteristics will change greatly depending on the current applied and cannot secure sufficient impedance.
Despite the fact that these components have dimensions of 1.6 x 0.8 x 0.8 mm (L x W x H), they can support a high-rated current of 500 mA.
This considerably lowers impedance variation during current application. The parts may work at 400 mA of current and temperatures as high as 125 °C.
The performance of automobile cameras has significantly improved as a result of the widespread adoption of advanced driver assistance systems (ADAS).
As a result, there is an increasing need for interfaces with more speed and capacity. Vehicle camera systems that use LVDS transmission are using a PoC strategy, which combines power and data transmission onto a single coaxial cable.
PoC provides power and data transmission, reducing the need for wire harnesses. This helps to lighten the vehicle’s weight and creates room for space savings.
In a PoC circuit, efficient filtering is required to isolate the data from the power supply. Usually, this consists of two to four inductors.
Such filters require inductors with high impedance for AC components at all frequencies, from low to high.
The new MLJ1608WG Series is highly optimised for fulfilling such criteria, achieving impedance values of 1000 or greater over a wide frequency range.
