Fixed Inductors

Inductors are passive electronic components that store energy in a magnetic field when an electric current flows in its windings. A fixed inductor is a type of inductor with a set inductance value, which is determined by the number of turns and size of the conductive metal. A popular fixed inductor, type HKQ0603S1N1C-T, is widely used in a number of applications, and is suitable for use in miniature circuit boards (PCB) due to its small size.

Applications

The HKQ0603S1N1C-T is especially suited for use in RF circuit designs, due to its low loss in the frequency range of 50 kHz–1 GHz, and its good power handling capabilities. It is commonly used in antenna tuning applications, where the inductor is used to match the impedance of the antenna to the impedance of the transmission line. This is done to ensure maximum energy transfer from the antenna to the transmission line. Other applications include radio-frequency (RF) amplifiers and oscillators, power supplies, resonant circuits, and signal conditioning circuits.

Design Characteristics

The HKQ0603S1N1C-T is a surface-mount device, with a size of 0.6 × 0.3 × 0.1 inches (0.7 x 0.4 x 0.1 mm). It has a goldplated case and is manufactured with a high-temperature co-fired ceramic (HTCC) substrate. It is RoHS Compliant, and rated for an operating temperature of -25°C to + 85°C. The inductance value is 1.9 nH and does not change significantly with temperature. The self-resonant frequency of the HKQ0603S1N1C-T is 2.1GHz, which is significantly higher than the operating bandwidth.

Working Principle

At the heart of the HKQ0603S1N1C-T, is a coil of wire and core material. When an electric current passes through the coil, it creates an electromagnetic field around the coil, which stores energy. The inductance of the coil is determined by the core material and the number of turns in the coil. The core material also acts to increase the magnetism of the field, which increases the amount of stored energy.As the current flow through the coil changes, the magnetic field in the coil also changes, which induces a voltage across the terminals of the coil. This voltage can be calculated using Faraday\'s law of induction. The more changes in current, the greater the induced voltage across the coil and the greater the inductance.

Conclusion

The HKQ0603S1N1C-T is a miniaturized, surface mount, fixed inductor with a high self-resonant frequency and good power handling capabilities. It is suitable for use in small PCBs, and is widely used in radio and signal conditioning applications. Its design features and working principle make it an ideal choice for these applications.
