Fixed inductors (also known as non-moving inductors) have been used in various electronic circuits for many years. The AQ1058N2J-T is a type of fixed inductor manufactured by Sigma Systems. Its application and working principle are discussed in this article.

The AQ1058N2J-T is an axial leaded inductor deployed in small cuircuits for EMI’s purpose. It is SMT compatable and provides small size and high reliability. This device is mainly used in mobile communication products, including GSM3G, radio frequency (RF) devices and shallow digitalk communication equipment. AQ1058N2J-T inductors are widely used in antenna matching, impedance matching, impedance tuning, signal transmission and power supply filtering applications.

AQ1058N2J-T works on the principle of inductance. The product has three major components - a conductive coil, a core and some terminals. The electrical current which flows through the coil with an air core creates a magnetic field and this magnetic field induces an electric current whenever there is a change in the flow of current through the coil.

When the current is flowing in one direction, it produces a steady state magnetic field which does not change, and thus no electric current is induced. However, when the current changes direction, this creates varying and changing magnetic field, causing Eddy current. The Eddy current induction creates a voltage which will oppose the change in current. This is the principle behind the AQ1058N2J-T’s fixed inductor.

The AQ1058N2J-T has a high performance of up to 1.2GHz and a maximum current of 4mA, and its small size makes it easy to deploy and integrate into small devices. The device’s external dimension is only 2.5 mm x 4 mm with a lead pitch specification of 0.35 mm. Additionally, it features an impedance of 80 ohms and an inductance of 0.35 uH. Moreover, it has an excellent temperature coefficient of only 17ppm/°C and is Compatible with the SMT process.

In conclusion, The AQ1058N2J-T is a fixed inductor that works on the principle of inductance. This device is mainly used in mobile communication products for various applications from antenna matching to power supply filtering. The product has a high performance with a low power consumption and a small size. It also provides excellent temperature coefficient specifications and is fully SMT compatible. Therefore, it is an ideal choice for small EMI’s projects in various electronic circuits.
