AVX
has launched a new series of thin-film multilayer chip inductors for
high-frequency automotive signal and power applications. The Accu-L Series
inductors — qualified to the AEC-Q200 standard — feature high Q, high
self-resonant frequency (SRF), low DC resistance (Rdc), and robust high-frequency
performance from 450 MHz to 2,400 MHz.

Automotive
designs demand apex accuracy, which, in turn, mandates matching networks and
filters in vehicle-to-vehicle communications, infotainment, vehicle location,
keyless entry, and radar systems.

These
thin-film chip inductors are small, ruggedly constructed, and deliver
ultra-tight inductance tolerances. AVX claims that inductors offer intra-lot
and lot-to-lot physical and electrical consistency, which makes them highly
suitable for automotive signal and power applications.

“Accu-L
Series inductors virtually eliminate the variances in dielectric quality,
electrode conductivity, and physical size that are inherent to ceramic
capacitor technologies,” said Larry Eisenberger, principal technical marketing
engineer at AVX.

The
automotive-grade Accu-L inductors are rated for use in temperatures ranging
from –55°C to 125°C. They are RoHS-compliant and provide lead-free compatible
nickel- and solder-coated terminations. Moreover, they are compatible with
flexible and alumina circuit boards as well as automated reflow and hand-soldering
processes.

The Accu-L Series inductors boast low profile
and are available in 0402 and 0805 chip sizes. Inductance values for 0402 parts
extend from 0.56 nH to 6.8 nH, inductance tolerances span ±0.05 nH to ±0.5 nH,
and minimum SRF values range from 6,500 MHz to 20,000 MHz. Next, inductance
values for 0805 parts extend from 1.2 nH to 22 nH, inductance tolerances span
±0.1 nH to ±5 nH, and minimum SRF values range from 1,400 MHz to 20,000 MHz.
