INF
The 1012 THT Power Inductor is a high-performance through-hole electromagnetic component of INF’s FAMI series, specially designed for B-end power conversion and portable electronic equipment manufacturing applications. As a shielded THT ferrite core power inductor, it adopts an optimized material formulation and a fully shielded structural design, which minimizes stray magnetic fields to the greatest extent and avoids electromagnetic interference with adjacent components on the circuit board. This FAMI THT power inductor for DC-DC converters boasts an industry-leading saturation current rating of up to 19.7 A and an ultra-low DC resistance starting at 3.8 mΩ, ensuring high energy conversion efficiency and stable current output in power supply circuits. With a wide operating temperature range of -40 °C to +125 °C, it maintains consistent and reliable performance in extreme industrial and consumer electronic working environments, making it an ideal choice for DC/DC converters, power supplies, battery chargers and portable electronic devices such as notebooks. Its radial lead design and standard through-hole dimensions are perfectly compatible with traditional manual and automated THT assembly processes, fully meeting the mass production needs of B-end electronic manufacturers.
The full shielded construction of the 1012 THT Power Inductor effectively reduces stray magnetic fields to the minimum, completely eliminating electromagnetic crosstalk with other electronic components on the PCB board. This design is crucial for the high-density circuit design of B-end power modules and portable electronic devices, ensuring the stable operation of the entire equipment system and avoiding signal interference caused by magnetic field leakage.
As a high saturation current radial lead power inductor, it supports a maximum saturation current of 19.7 A and a minimum DC resistance of only 3.8 mΩ. This performance not only meets the high-current power supply requirements of industrial equipment and portable electronic devices but also minimizes the power loss in the circuit, significantly improving the energy conversion efficiency of the power supply system. The product strictly distinguishes between saturation current (ISAT) and temperature rise current (IR), avoiding inductance value drop and overheating failure in actual industrial use.
The 1012 THT Power Inductor has an operating temperature range of -40 °C to +125 °C, which can adapt to various harsh working environments, including low-temperature industrial control equipment in cold storage, high-temperature automotive electronics and portable devices with high heat generation during operation. Its optimized material and structural design ensure no obvious parameter drift within the full temperature range, meeting the long-term stability requirements of B-end electronic products.
The radial lead THT structural design and standard dimensional parameters of this power inductor are compatible with most industrial PCB board layouts, and it can be seamlessly integrated into automated THT assembly lines, improving the production efficiency of B-end manufacturers. At the same time, it is also suitable for traditional manual assembly, with strong flexibility for small-batch prototype production.
This section lists the core structural and electrical performance indicators of the INF 1012 THT Power Inductor, covering the core material, structural type and key performance parameters for B-end users’ selection.
