Ferrite beads for miniature suppression
Miniature ferrite beads provide wide frequency range attenuation, typically from 30MHz to several hundred megahertz.
Module takes the RF expertise out of ID
Combines the latest in ceramic materials with a breakthrough in ceramic module and inductive coupling technology to produce a very easy to use module.
Just half the volume and 60% of the mounting area, these new chip coils measure 0.8 x 0.4mm with a low 0.4mm profile, which combined with a resin-coated surface, makes them particularly suitable for high-density mounting.
The wire-wound construction with a miniature aluminium core is ideal for high frequency applications.
Indeed, the LQW04A series features high Q value in the high frequency range, has high self-resonant frequency and offers stable inductance at high 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 1.1 to 22nH, allows designers to select the most appropriate part of their application.
These chip 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.
The LQW04A chip coils are manufactured in Japan using Murata's advanced manufacturing techniques and parts are readily available on 8 to 10 week lead times.
