Murata Introduces Miniature High-Frequency Wire Wound Chip Coils
SMYRNA, Ga., Jan. 9 -- Murata Electronics North America, a world-leading innovator in electronics and the largest global supplier of ceramic passive components, today introduced a miniature high-frequency wire wound type chip coil (LQW04A series). The 03015 EIA sized coils (0.8mm X 0.4mm) were developed using advancements in mounting techniques and materials. Murata's chip coils are ideally suited for high-frequency circuits used in mobile devices such as cell phones and Personal Digital Assistants (PDAs).
Compared to the traditional size of EIA 0402 wire wound chip coils, the new LQW04A series reduces the mounting area by 40 percent and the height is a diminutive 0.4mm. These technology advancements also lay the groundwork for future production of even smaller and lower profile devices. The smaller size is a benefit to engineers who strive to create condensed profile devices.
In addition to designing a compact component, Murata's new series boasts stable inductance with high self-resonance frequency, as well as high Q-values at high frequencies. These ideal characteristics were achieved by adopting a horizontally-wound structure which minimizes parasitic losses.
"Murata's unique ability to provide smaller components with improved features demonstrates our ongoing commitment to anticipate market demands," said Deryl Kimbro, product manager EMI filters and chip inductors for Murata Electronics North America. "The advancements in Murata's coil manufacturing technology, as seen in the LQW04A series, is a true testament of our research and development strength."
The LQW04A series inductance is 1.1-22nH and includes the inductance tolerance of +/-0.5nH/+/-5%. Q values range from 55 to 75 in the GHz range. Murata's new high-frequency wire wound type chip coils are available for the sample price of $0.10. Additional purchasing info can be found online at www.murata.com/. Lead time is approximately six to eight weeks.
Murata offers a variety of coils, including choke coils with low DC resistance intended for power supply circuits, general-purpose chip coils suitable for voltage increases, and high-frequency chip coils that provide low-loss and high-Q characteristics at high-frequencies. Users can select the optimum characteristics by choosing from monolithic, film or wire wound construction and a wide range of inductance values and tolerances. Some types also allow for magnetic shielding. In addition to traditional chip coils, Murata also designs a range of miniature delay lines with excellent delay accuracy.
