Chip inductor offers high Q in a miniature size

Two chip inductors from Bourns, the Model CWF1610 and CWF2414 have a wirewound construction, claimed to unlock enhanced performance characteristics for RF signal processing and DC power line applications.

The CWF1610 and CWF2414 chip inductors are based on a wirewound construction around a ferrite core to offer high values of inductance, Q values, and self-resonant frequency, plus low DC resistance in a compact size. Operating temperature range is  -40 to +125 degrees C. According to Bourns, these features make the chip inductors suitable 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.

According to Bourns, the thicker wirewound construction around the core achieves lower DC resistance and high Q values of 13 to 16 in these miniature-sized inductors. In addition, the high Q values offer designs a high impedance at resonant in inductive-capacitive LC circuits, and low loss at high frequency operation.

The Model CWF1610 and CWF2414 chip 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 860/1100mA and rated current up to 700/1300mA, the chip inductors maintain high inductance at a greater peak current matching the requirements in DC power line applications.

The Model CWF1610 and CWF2414 chip inductors are available now and are RoHS- compliant and halogen-free.

Bourns manufactures position and speed sensors, circuit protection solutions, magnetic components, microelectronic modules, panel controls and resistive products.

Headquartered in Riverside, California, USA, Bourns serves a broad range of markets, including automotive, industrial, consumer, communications, medical (low/medium risk) and audio.
