Token offers The Smallest Flat Top Air Core Coils (Spring Inductors) for Only (1.8 x 2.0 x 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 miniaturised 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 x 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 their application.
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 for more information.
