Fixed inductors are electrical components in which the inductance value does not vary with time or the applied voltage. The most common types of fixed inductors are air core, ferrite core, powder core and multi-layer ceramic core. Among them, the most commonly used type is the multi-layer ceramic core. The HKQ04022N2S-E is a new series of high-performance multi-layer ceramic core inductors from the Shenzhen Hongkeqing Electronic Co., Ltd.

The HKQ04022N2S-E is designed for a variety of single-output DC/DC converters and pulse amplifier applications. It features an operating frequency range of between 10kHz and 1MHz, with a maximum inductance value of 47 µH ± 20%. The inductor\'s construction includes a ferrite core material, which provides good EMI and RFI suppression. Its package size is small (4.3mm × 3.2 mm × 2.85 mm), and its weight is ultra-light (1.7g). It has a maximum DC current rating of 1.5A and an operating temperature range of -40°C to +85°C.

The HKQ04022N2S-E has a wide range of applications. It can be used in single-output DC/DC converters, pulse amplifiers and other switching power supply circuits. In these applications, the inductor functions as a filter, suppressing high frequency noise and controlling ripple current. It is also widely used in switching power supplies, DC to DC converters, motor drives, LED lighting and LED displays.

The working principle of the HKQ04022N2S-E involves the creation of a magnetic field generated by the coil in which the core is wound. As current passes through the coil, the magnetic field induces a voltage and a current in the coil. This current, or inductance, is the main principle of the inductor. The HKQ04022N2S-E is a DC rated inductor, meaning that it can handle a constant current, and its inductance value is not effected by variations in the applied voltage or frequency.

The HKQ04022N2S-E series of the fixed inductors has excellent performance characteristics, including low DCR, high current handling, tight inductance tolerance and wide operating temperature range. It is suitable for a variety of circuit applications, and its small size and low weight makes it an ideal choice for space constrained applications. The HKQ04022N2S-E series of fixed inductors has been used in many designs, and is recognized as one of the top quality fixed inductors on the market today.
