Fixed inductors, also known as coils, are passive electronic components that store energy in a magnetic field produced by electrical current. HM61-20222LFTR13, is a fixed inductor, designed for a wide range of applications. The inductor is constructed with frame, conductive coil, terminal and plastics. The housing allows for easy mounting and reliable attach to application board. This inductor is designed for use in power supplies and high-efficiency DC-DC converters.The frame of HM61-20222LFTR13 is designed to minimizing the stray magnetic fields and according with European requirements for EMC, class B level. It features an operating temperature range of -40°C to 125°C and a storage temperature range of -40 °C to 85°C. The inductor has an inductance of 2.0mH and rated current of 2.2A. It can and maximum DC resistance of 0.704 ohm at 25 ℃.The working principle of a fixed inductor is based on the Faraday principle of electromagnetic induction. This states that when a conductor is placed in a changing magnetic field (electromotive force), it will be induced with a current. The current and magnetic field strength associated with the inductor is proportional to the rate of change of the Flux Linkage of the coil induced in the core.The application fields of HM61-20222LFTR13 include but are not limited to switching regulators, DC/DC converters, DC/AC inverters, AC/DC converters and motor drives. So, it is suitable for applications that require a precise and reliable power source. The inductor is also ideal for use in LED drivers, AC/DC switching power supplies, DC/DC converters, PC motherboards, and industrial control boards. Additionally, due to its low profile, it is suitable for slim and compact designs and application boards.In terms of structure, the inductance loop consists of a winding, which is made up of several turns of copper wire wound around a coil core. The number of turns determines the value of the inductance. The core is made of materials with different permeability such as iron, ferrite, iron-powder, or even air for expanded applications. The number of turns depend on the type of inductor and application field. The influence of the core’s type and material is the quality factor (Q) of the inductor, which determines its losses.The HM61-20222LFTR13 is a high-performance fixed inductor designed for applications requiring a precise and reliable power source, such as switching regulators, DC/DC converters, DC/AC inverters, AC/DC converters and motor drives. The inductor is designed with a frame to minimize the stray magnetic fields and rated at 2.0mH and current of 2.2A. It operates in a wide temperature from -40°C to 125°C and storage temperature up to 85°C. It features a low-profile SMD package is suitable for slim and compact designs.
