regulatory compliance, ensuring that
necessary benchmarks are met.
Smaller components enable PoC system
integration into tight vehicle spaces without
sacrificing performance.
conditions, including extreme temperatures.
With vehicles now expected to
operate in temperatures as high as
150°C (302°F), maintaining reliable sensor
and camera functionality is critical
for safe operation.
Modern inductors are also optimized
for high-current applications, a growing
requirement as vehicle systems demand
more power. The power needs of components
like cameras and sensors have
increased, and inductors must now handle
higher current loads, from 1W to
5W, while ensuring stable performance.
Supporting compliance with
international standards
As automakers integrate PoC technology
to simplify their vehicle systems,
compliance with international standards
is essential. PoC technology helps manufacturers
meet stringent regulations
related to safety, performance and environmental
impact.
The reduced vehicle weight resulting
from PoC's simplified wiring contributes
to improved fuel efficiency, while
the streamlined electrical system design
minimizes the risk of errors and
malfunctions.
Additionally, system-level support is
available for automotive manufacturers,
including tools like scattering-parameter
data analysis. This support
ensures that PoC systems meet the
technical requirements of each vehicle
design while complying with industry
standards. Automakers can optimize
their PoC systems for performance and

The future of PoC in automotive
systems
PoC technology represents a significant
step forward in the design of automotive
electrical systems. It is a streamlined
solution that supports modern vehicles'
power and data needs by reducing
weight, simplifying wiring harnesses, and
minimizing electromagnetic interference.
TDK is at the forefront of Power over
Coaxial (PoC) technology innovations,
driving advancements that address the
automotive industry's increasing demand
for more efficient and reliable
systems. Focusing on developing highperformance
components like advanced
inductors and filters, its solutions are
optimized for the unique challenges of
PoC applications.
Automakers and the automotive industry
rely on cutting-edge inductors
with innovations like bifilar winding
technology that help reduce electromagnetic
interference, maintain signal
integrity, and enable high-current capabilities,
all while minimizing space
requirements. It's necessary to work
with partners to refine these technologies,
empowering automakers to
streamline their vehicle designs, improve
system performance, and meet
stringent industry standards, paving
the way for more sophisticated and
efficient automotive systems.
Innovations in components like inductors
and the introduction of bifilar
winding technology continue to push
the boundaries of what PoC systems
can achieve. PoC will play an increasingly
important role in enabling future
advancements in automotive technology,
supporting the demands of ADAS
and autonomous driving systems.
