Token offers The Smallest Flat Top Air Core Coils (Spring
Inductors) for only (1.8 × 2.0 × 2.0 mm). The latest range of
air core surface mount coils from Token is fully compliant with
RoHS legislation and available immediately in full production
volumes. The (TRAM) series provides a cost effective and
miniaturized alternative to the earlier version.
The wire-wound construction with a miniature core is ideal for
high frequency applications. These new SMD coils measure 1.8
× 2.0 mm with a low 2.0 mm profile, which combined with a
mould-sealed surface, makes them particularly suitable for high-density mounting.
Indeed, the (TRAM) series features high Q value in the high frequency range, offers stable inductance
at high frequency and has high self-resonant frequency. Meanwhile, the low DC resistance design is
ideal for low loss, high output and low power consumption. A wide range of devices in the series, with
inductance values ranging from 3.9 to 538nH, allows designers to select the most appropriate part of
These chip air core coils are aimed at high frequency circuits in telecommunications equipment,
including power amplifiers, antenna modules, VCOs and SAWs, and in mobile phones, such as GSM,
CDMA, and PDC. Other applications include digital TV tuners, wireless LAN and Bluetooth devices.
This new SMD inductor provides a narrow inductance deviation with a complete range of inductance
values, making chip inductors an excellent choice for high frequency circuit matching. SMD coils can
be customed designs and tighter tolerances available on request. Application of RF air core coil
specific designs also available including different inductance values and Q specifications.
Custom parts are available on request. Token will also produce devices outside these specifications to
meet specific customer requirements, please contact our sales or link to Token official website “RF
Inductors” for more information.
