The **AIAC-1812-R10** is an air-core power inductor manufactured by Abracon. It belongs to the AIAC-1812 series, which is designed for high-frequency applications where high Q (Quality Factor) and high current handling are required. --- ### ## Technical Specifications The following table summarizes the core electronic characteristics of the **AIAC-1812-R10**: | Parameter | Specification | | :--- | :--- | | **Inductance** | 100 nH (0.10 µH) | | **Tolerance** | ±5% (Standard) | | **Case Code** | 1812 (4.5 x 3.2 mm) | | **DC Resistance (Max)** | 0.035 Ω (35 mΩ) | | **Rated DC Current (Max)** | 2.5 A | | **Self-Resonant Frequency (Min)** | 600 MHz | | **Quality Factor (Q) Min** | 100 (at 150 MHz) | | **Operating Temperature** | -40°C to +125°C | --- ### ## Key Features and Construction 1. **Air Core Design**: Unlike ferrite core inductors, the AIAC series uses an "air core" (hollow center). This ensures that the component does not suffer from magnetic saturation, making it extremely stable across varying current levels. 2. **High Q Factor**: The high Quality factor indicates low energy loss, which is critical for RF (Radio Frequency) tuning and filtering circuits. 3. **Flat Top Surface**: The mechanical structure includes a flat top surface which makes it compatible with high-speed automated Pick-and-Place SMT (Surface Mount Technology) assembly. 4. **Excellent Solderability**: The leads are typically pre-tinned, ensuring strong solder joints and reliability in high-vibration environments. --- ### ## Typical Applications Because of its high resonant frequency and current handling, the AIAC-1812-R10 is commonly found in: * **RF Communications**: Used in transmitters and receivers for signal filtering. * **Impedance Matching**: Matching the impedance between different stages of an RF amplifier. * **High-Frequency Power Supplies**: Serving as a ripple filter in DC-DC converters where high efficiency is required. * **Satellite/GPS**: Tuning circuits for high-frequency satellite communication.
