The **AIAC-2015C-R100** is a high-frequency, air core power inductor manufactured by Abracon. These components are specifically designed for applications requiring high Q-factors and low power loss at high frequencies. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and electrical characteristics. | Parameter | Value | | :--- | :--- | | **Inductance** | 100 nH | | **Tolerance** | ±5% (indicated by 'J' usually, or standard 'C' series tolerance) | | **Q-Factor (Min)** | 100 @ 150 MHz | | **DC Resistance (DCR Max)** | 6.3 mΩ | | **Rated Current (Irms)** | 3.5 A | | **Self-Resonant Frequency (SRF)** | 1.1 GHz | | **Operating Temperature** | -40°C to +125°C | --- ### 2. Key Features * **Air Core Construction:** Unlike inductors with ferrite cores, air cores do not saturate. This means the inductance remains constant regardless of the current passing through it. * **High Q-Factor:** Provides low signal loss, making it ideal for resonant circuits. * **Surface Mount (SMD):** Designed with a flat top for automated "pick and place" assembly processes. * **Compact Footprint:** The "2015" designation refers to the physical size (approximately 5.0mm x 3.8mm). --- ### 3. Common Applications Due to its high frequency stability and high current handling, it is typically used in: 1. **RF Circuits:** Used in impedance matching networks and filters for radio frequency transmitters and receivers. 2. **Telecommunications:** Base stations and satellite communication equipment. 3. **High-Speed Switching:** Power supplies where low losses are critical at high frequencies. 4. **Signal Conditioning:** Decoupling and EMI/RFI suppression in high-frequency signal paths. --- ### 4. Comparison: Air Core vs. Ferrite Core For electronic design considerations, here is why the AIAC-2015C-R100 might be chosen over a standard inductor: | Feature | AIAC-2015C-R100 (Air Core) | Standard Ferrite Inductor | | :--- | :--- | :--- | | **Saturation** | None (Linear performance) | Subject to magnetic saturation | | **Frequency Range** | Excellent at High Frequency | Limited by core losses | | **Inductance Value** | Typically Lower (nH range) | Typically Higher (µH to mH range) | | **EMI** | Higher radiated field | Lower (shielded options available) |
