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.
Over a wide range of inductance values, from 1.0 to 120nH, DC resistance of these chip inductors is specified from 30mohm to 1ohm (typical), 70mohm to 1.3ohm (maximum).
Further features include high self-resonance frequency and a high Q, cited at better than 30 at 800MHz.
The low DC resistance of the LQG15HS chip inductors will be of particular interest to designers of mobile wireless consumer products, such as those based on the Bluetooth protocol, where reducing power consumption is critical to extending battery life.
They are equally applicable to high frequency circuits in more general purpose rf and microwave equipment such as power amplifiers, antennas, VCO and SAW devices.
The devices are compliant with the RoHS directive, with an outer electrode of plated tin, and support high-temperature reflow soldering (260C).
The chip inductors are packaged in the 0402 case size (1 x 0.5mm) with a tight tolerance in physical dimensions of +/-0.05mm.
The LQG15HS series is designed as a drop-in replacement for the LQG15HN series, although these will continue to be supported.
