Miniature chip coils are compact
low-cost chokes
Good news for designers looking for miniature chip coils for use as chokes.
Murata's LQM18F series of multilayer miniature chip coils is now readily available in production volumes Choke coils in the LQM18F series are smaller than comparable multilayer and wire-wound devices and are keenly priced to be cost competitive, particularly against wire-wound alternatives

Ferrite beads for miniature suppression
Miniature ferrite beads provide wide frequency range attenuation, typically from 30MHz to several hundred megahertz.
The devices measure just 1.6 x 0.8 x 0.8mm, making them ideal for choke applications in DC power lines in portable equipment.
In performance terms, the chip coils offer a higher rated current than competing multilayer coils and chokes.
They are specified at 50, 80, 120 and 150mA for devices in the inductance ranges of 10, 4.7, 2.2 and 1uH, respectively.
The LQM18F series parts also feature low DC resistance, superior DC bias figures and their magnetically shielded structure provides excellent crosstalk and magnetic coupling characteristics.
Applications include choke circuits in DC power lines of compact mobile and handheld equipment such as mobile phones, digital still cameras, video cameras and music players, as well as in other data processing and entertainment systems.
Manufactured in Japan, using Murata's advanced processes, the devices are now in mass production, and available in manufacturing volumes on typically, 8 to 12 weeks lead time.
All parts are fully RoHS compliant.
