New Chip Inductor Series Offering High Q in Miniature Size

Bourns’ new Model CWF1610 and CWF2414 chip inductors feature wire-wound construction to unlock enhanced performance characteristics for RF signal processing and DC power line applications.

Today, Bourns, Inc., a leading manufacturer, and supplier of electronic components, announced the CWF1610 and CWF2414 Chip Inductor Series. These inductors employ wire-wound construction on a ferrite core to offer high inductance values, Q values, and self-resonant frequency, plus low DC resistance in a compact size with an operating temperature range of -40 to +125 °C. These features make this series ideal for RF signal processing, resonant circuits, decoupling, noise filters, and DC power line applications for audio headsets, cable modems, set-top boxes, hard disk drives, tablets, and various mobile electronic devices.

Compared to multilayer or film technology, a thicker wire-wound construction around the core makes it possible to achieve lower DC resistance and high Q values of 13 to 16 in these miniature-sized inductors. In addition, the high Q values provided in the new inductors -offer designs a high impedance at resonant in inductive-capacitive LC circuits and low loss at high-frequency operation. Bourns® Model CWF1610 and CWF2414 chip inductors also feature a high self-resonant frequency, translating to low distributed capacitance and maintaining inductive characteristics over a wide frequency span. With saturation current up to 860/1100 mA and rated current up to 700/1300 mA, the new chip inductors from Bourns maintain high inductance at a more significant peak current matching the requirements in DC power line applications.

Bourns® Model CWF1610 and CWF2414 Chip Inductors are available now and are RoHS compliant and halogen-free.
