The **AC30-R15K-RC** is a high-performance power inductor, typically manufactured by **Bourns**. It belongs to the AC series of air-core inductors, which are designed for high-frequency applications where low losses and high "Q" (Quality Factor) are essential. ### 1. Key Technical Specifications The following table outlines the primary electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 15.0 nH (Nanohenries) | | **Tolerance** | ±10% | | **Current Rating (Idc)** | 3.0 Amperes (Maximum) | | **DC Resistance (DCR)** | 4.6 mΩ (Maximum) | | **Self-Resonant Frequency (SRF)** | 2.5 GHz (Minimum) | | **Operating Temperature** | -40°C to +125°C | | **Mounting Type** | Surface Mount (SMD) | --- ### 2. Core Features & Construction * **Air-Core Design:** Unlike inductors with ferrite cores, this part uses an "air core." This eliminates core losses and saturation issues, making it ideal for high-frequency RF (Radio Frequency) circuits. * **High Q Factor:** The construction allows for very low energy loss, which is critical for maintaining signal integrity in resonant circuits. * **Pick-and-Place Compatible:** The "RC" suffix usually indicates RoHS compliance and the physical design (often including a flat top cap) allows it to be handled by automated assembly machines. * **Compact Footprint:** Designed for high-density PCB layouts where space is at a premium. --- ### 3. Common Applications Due to its high frequency and high current capabilities, the AC30-R15K-RC is commonly used in: 1. **RF Amplifiers:** Used for matching networks and bias tees. 2. **Wireless Communication:** Found in cellular base stations, Wi-Fi routers, and GPS modules. 3. **Filters:** High-pass, low-pass, and band-pass filters in the GHz range. 4. **Power Supplies:** High-frequency switching regulators requiring low DCR. --- ### 4. Part Number Breakdown * **AC30:** Series designation (Air Core Inductor, size/style 30). * **R15:** Inductance value code (R15 = 0.15 µH or 15 nH). * **K:** Tolerance code (K = ±10%). * **RC:** RoHS Compliant.
