Bourns has launched two series of wire wound chip inductors that reduce the size for DC power line filters in audio headsets, cable modems, set-top boxes, hard disk drives, tablets and other mobile electronic devices.
The CWF1610 and CWF2414 Chip Inductor Series have an inductance from 1 to 22uH with a a Q value of 16 and 13 respectively, saturation current up to 860/1100 mA and rated current up to 700/1300 mA.
Compared to multilayer or film technology, a thicker wire wound construction around the core makes it possible to achieve lower DC resistance and higher Q values. The high Q values provided in the new inductors offer designers a high impedance at resonant in inductive-capacitive LC circuits, and low loss at high frequency operation. The chip inductors also feature a high self-resonant frequency, which translates to low distributed capacitance and maintained inductive characteristics over a wide frequency span, and maintain high inductance at a greater 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
