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.
The combination of Murata's smart ceramic processing technology, unique piezoelectric material and advanced packaging technology has facilitated the development of a range of small and thin ceramic resonators offering high oscillation frequency and remarkable oscillation tolerance.
These products are designed for use as a stable timing source (clock oscillators) for microcontrollers and microprocessors.
The CST family of Ceralock parts have built-in load capacitors, removing the need for external devices.
Selected plated through hole and surface mount versions have been made available suitable for both industrial and consumer use.
Certain plated through hole versions have been selected, to meet the requirements of a range of consumer applications including DTMF generators, remote control units and automated office equipment.
They are stable over a wide temperature range and exhibit superior shock resistance when compared to quartz crystal alternatives.
Devices with oscillation frequencies of 3.6, 4, 6, 8 and 10MHz are available with a built in capacitance of 15pF, whereas 16 and 32MHz parts come with 5pF load capacitor built in.
The surface mount parts now available as standard are small and low profile, making them ideal for designs requiring high-density packaging.
They are offered in a wider frequency range, from 2 to 32MHz and, depending on part selected, built in load capacitors vary from 5 to 39pF.
Applications include electronic control circuits for small electronic devices such as video cameras, audio-visual equipment and PC peripherals such as DVD and CD-ROM players and hard disk drives.
