Meeting new performance demands
requires a shift towards integrations like
embedded passives, high-temperature
dielectrics, lower core material
permeability, and compact packaging
design. These devices should also
be in alignment with standards like
AEC-Q200 for reliability, ISO 16750 for
environmental testing, LV 123 for high-
voltage electrical validation."

Over time, vibration may lead to cracked solder joints,
degraded magnetic performance, or failure of the
component's internal structure. Automotive-grade
inductors must therefore be mechanically robust and
tightly secured to the printed circuit board. Some
manufacturers now perform custom vibration testing
based on OEM-specific profiles and have developed
new inductor families designed to meet sustained
mechanical acceleration.
Humidity, contamination, and temperature
extremes further complicate the reliability
profile. Vehicles routinely operate in cold, hot,
snowy, salty, and heavy moisture environments
that create conductive paths and corrosion
risks. Passives used in exterior modules or near
wheel wells must use protective coatings and
housing materials that limit moisture ingress and
mechanical fatigue.
And, in high-voltage systems, safety adds yet
another layer of constraint. Capacitors, inductors,
and resistors are directly involved in EMI
suppression and signal filtering for
braking systems and driver-
assist functions.
