Bourns Chip Inductors Feature High Q Value in a Miniature Size 

Bourns, Inc., a manufacturer and supplier of electronic components, recently announced the CWF1610 and CWF2414 Chip Inductor Series. They employ wirewound construction on a ferrite core to offer high values of inductance, 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 the series suited well 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 wirewound construction around the core makes it possible to achieve lower DC resistance and high Q values of 13 to 16 which provide product designers a high impedance in inductive-capacitive LC circuits, and low loss at high frequency operation. Both  inductors also feature a high self-resonant frequency, which translates to low distributed capacitance and maintained 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 inductors maintain high inductance at a greater peak current matching the requirements in DC power line applications.
