ELJ-FCR68KF application field and working principle

Fixed inductors, commonly known as inductors, are electronic components that store energy in the form of magnetic fields by applying a current through a coil. In turn, a voltage is induced when the inductance changes due to a change in the electric current. An inductor will oppose a change in the current; the opposition offered by the inductor increases as the rate of current change increases.

The ELJ-FCR68KF is a family of fixed inductors developed by Panasonic specifically for use in Wireless Local Area Network (WLAN) and Wi-Fi applications. This family of inductors is certified to compliance the 802.11aWLAN and Intel® Centrino® Wi-Fi standard. The ELJ-FCR68KF is an ultra-small, surface-mountable product series with excellent heat resistance and Surge Resistance to 500V.

The ELJ-FCR68KF features a wound construction with air-core and ferrite-bead material that provides a low DC resistance, allowing for stable operation. The device has a wide inductance range from 10nH to 47uH with a tolerance of ±20%, which makes it well-suited for applications involving voltage regulators, voltage DC-DC converters, power supplies and other related circuit applications.

The ELJ-FCR68KF is designed to function as a miniaturized low-ESR-inductor. It is optimized for use with low-ESR ceramic capacitors and follows strict SQC (Six-Sigma Quality Control) manufacturing and testing standards. The device also has a wide operating temperature range up to +125°C.

The ELJ-FCR68KF utilizes magnetically-coupled energy between the inductor and capacitor for optimal filtering, thereby improving the efficiency and stability of the system. The two components work together to decrease ripple current and noise, while also providing voltage stabilization for the circuit. The ELJ-FCR68KF also offers excellent EMI (electromagnetic interference) suppression characteristics, providing protection against external interference.

The various characteristics of the ELJ-FCR68KF make it a versatile and reliable choice for a multitude of applications from wireless networks to consumer electronics. It is ideal for use in routers, access points, data cards, notebooks, personal computers, and other consumer electronics requiring precise performance. Its excellent size, heat resistance, power handling, and low-ESR design make it a suitable choice for both commercial and consumer markets.
