The part number **00BAC-R** refers to a specific type of high-performance **Chip Inductor** (specifically a Wire-wound Inductor) typically manufactured by companies like **Eaton (formerly Coiltronics)** or similar power electronic component specialists. --- ### 1. General Specifications These components are designed for high-frequency applications and power management. Below are the typical technical characteristics: | Property | Description | | :--- | :--- | | **Component Type** | Fixed Inductor / SMT Inductor | | **Construction** | Wire-wound on a ceramic or ferrite core | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Suffix "-R"** | Typically indicates **RoHS Compliance** (Lead-free) | | **Common Applications** | RF Circuits, DC-DC Converters, Filtering | --- ### 2. Key Electronic Functions The 00BAC-R series is engineered to perform the following roles in a circuit: * **Energy Storage:** In power supply circuits, it stores energy in a magnetic field during the "on" cycle and releases it during the "off" cycle. * **Noise Filtering:** It acts as a low-pass filter, blocking high-frequency noise while allowing DC or low-frequency signals to pass. * **Impedance Matching:** Used in RF (Radio Frequency) stages to ensure maximum power transfer between components. --- ### 3. Physical & Material Properties * **Core Material:** Usually Ferrite or Ceramic. Ferrite provides higher inductance values, while Ceramic is better for high-frequency stability. * **Termination:** Tin-plated over nickel or silver, ensuring high solderability for automated PCB assembly. * **Form Factor:** Designed with a small footprint to accommodate high-density mobile and telecommunications hardware. --- ### 4. Typical Use Cases 1. **Telecommunications:** Base stations and handheld radio devices. 2. **Computing:** Voltage Regulator Modules (VRMs) on motherboards. 3. **Consumer Electronics:** Power management in smartphones and tablets. --- ### 5. Identification Tip When sourcing this part, ensure you verify the **prefix** (e.g., *DR*, *MPI*, or *SD*). While "00BAC-R" acts as a specific identifier for the core series/size, different manufacturers might use slightly different full prefixes for their unique catalog numbers.
