TDK Unveils Smaller & More Powerful Components for Automotive Designers
In its relentless pursuit of smaller and more powerful mass-produced
magnetic components, TDK has introduced several products
for automotive design engineers recently. One is a series of thinfilm
power inductors that use the company's proprietary metallic
magnetic material as its core material. Others include a high-reliability
ferrite chip bead and, introduced in late October 2021, new
inductors for power-over-coax systems.
By using the metal magnetic material with high saturation magnetic
flux density, the DC bias characteristics needed for inductors for
automotive power circuits can be achieved while, by using a closed
magnetic circuit structure leakage flux is minimized, says TDK. The
new TFM201210ALMA inductors feature a mounting area downsized
approximately 22% from the company's conventional product.
Mass production began in August 2021.
Later in the fall, TDK announced the development and mass
production of the MMZ1608-HE series of high-reliability chip beads,
marking what it says is the first high-reliability chip bead specifically
designed for automotive applications associated with engine control
modules, anti-lock brake systems, electric power steering, electric
and hybrid electric vehicles, inverters and LED headlights.
Current inductors for automotive power-over-coax systems
There are four products in the series so far and TDK plans to
continue expanding the lineup of compact sizes and various impedances
to support a wide range of automotive specifications and
designs. A ferrite chip bead, also called an EMI filter or choke, is a
passive component that suppresses or filter high frequency noise in
circuits.
High-reliability chip beads for automotive applications
The newly developed ADL3225VM inductors for use in automotive
power-over-coax (PoC) systems were released in October. Measuring
at 3.2 x 2.5 x 2.5 mm, they provide a compact solution for
designers looking to reduce vehicle weight as manufacturers add
more sensors and cameras to accommodate expanding automotive
and advanced driver-assistance systems applications. The proprietary
structural design and wire winding manufacturing process
ensure high impedance over a broad bandpass, says TDK.

In high-temperature automotive environments such as engine
compartments, high-durability solder is increasingly used to prevent
solder cracks in the bonds between chip components and the
mounting substrate. Since high-durability solders do not stretch
easily and impart higher stress compared with conventional solders,
they place a large load on chip components and do not meet the
reliability requirements of existing chip beads.
