Advantages and Applications of EI28 Harmonic inductance

2026 03/10

I. Product Positioning
     This product is mainly targeted at the markets of small and medium power household appliances and industrial control equipment. For power modules and filter circuits that require stable inductance values, we have launched the EI28-00950701X type harmonic inductor. With precise parameters and compact design, it provides reliable electromagnetic conversion solutions for the equipment. 
Copper reactor
II. Core Selling Points of the Reactor
     Precise inductance, stable output: The inductance values of 1-3 pins are precisely controlled within 1.0 - 1.25 mH, with a precise tolerance of ±0.5 mm. This ensures stable inductance values during circuit operation, reduces current fluctuations, and enhances the overall performance of the equipment.
     Compact size, strong adaptability: The maximum size of the entire unit is 31mm × 31mm × 30mm. The details such as pin spacing and height have been meticulously designed (for example, the bottom pin spacing is 7.5 ± 0.5mm, 15 ± 0.5mm). It perfectly fits the PCB board layout of various miniaturized devices, eliminating the need to adjust the equipment structure for accommodating large-sized transformers.
Encapsulated reactor
      High-quality wire, durable guarantee: Using 0.70mm QA 2UEW enameled wire, it has excellent heat resistance and conductivity, extending the product's service life and reducing equipment maintenance costs.
