Fixed Inductors

Fixed Inductors are widely used in electrical and electronic circuits for various purposes, such as filtering, decoupling, frequency selection, and impedance transformation. One of the most widely used types for these applications is the LQW18AN58NJ80D. This particular model is a surface mount, high self-resonant, wire-bond type chip inductor manufactured by Taiyo Yuden Co., Ltd.

Application Field

The LQW18AN58NJ80D is an ideal choice for portable and consumer electronics applications, such as personal digital assistant (PDA) and smart phone. It is also suitable for applications requiring a high self-resonant frequency, such as radio-frequency (RF) designs for wireless communication systems. This inductor is particularly suitable for high frequency, wide-range applications up to 10GHz as it offers excellent electrical characteristics for these high frequency designs.

Working Principle

The working principle of the LQW18AN58NJ80D is based on its use of a wire-bonding technology. This unique technology enables a high self-resonant frequency of up to 10GHz in this inductor. Wire-bonding consists of fringing a single strand wire to the airbridge-type common terminal of the inductor and to a terminal on the PCB. This results in an inductance which is more efficient than conventional inductor on PCB pad due to the reduction of field leakage. The combination of wire-bonding and the airbridge-type structure enables the LQW18AN58NJ80D to effectively handle the high frequency and high current requirements of portable technology and consumer electronics applications.

Conclusion

In conclusion, the LQW18AN58NJ80D is an ideal choice for applications requiring a high self-resonant frequency, such as RF designs for wireless communication systems. It has an excellent electrical characteristics for applications up to 10GHz and offers superior performance compared to conventional inductors. Its wire-bonding technology provides a high self-resonant frequency and excellent current handling capacity, making it suitable for portable technology and consumer electronics applications.
