The part number **168-10-R** typically refers to a **High-Current Power Choke (Inductor)**, most commonly manufactured by brands like **Gowanda Electronics** or similar specialist magnetic component producers. Below is a breakdown of its technical specifications and characteristics. --- ### 1. Technical Specifications This component is an axial-leaded power inductor designed for high-reliability applications. | Parameter | Typical Value | | :--- | :--- | | **Inductance** | 10.0 µH | | **Tolerance** | ±10% (standard for "10" series) | | **Current Rating (DC)** | ~3.0 Amps to 5.0 Amps (depending on series) | | **DC Resistance (Max)** | ~0.040 to 0.060 Ohms | | **Package Type** | Axial Leaded (Through-hole) | | **Core Material** | Iron Powder or Ferrite | | **RoHS Compliant** | Yes (Indicated by the "-R" suffix) | --- ### 2. Component Breakdown The part number follows a standard nomenclature used in the magnetics industry: * **168**: The Series designation. This usually defines the physical size and the power handling capability of the inductor. * **10**: The Inductance value. In this case, 10 microhenries (µH). * **-R**: Indicates **RoHS Compliance**, meaning the part is lead-free and meets environmental safety standards. --- ### 3. Key Applications Because of its high current rating and robust axial design, the 168-10-R is used in: * **Power Supplies:** Used as a filter to smooth out ripples in DC-DC converters. * **EMI/RFI Filtering:** Acting as a choke to block high-frequency noise in electronic circuits. * **Industrial Controls:** Providing energy storage for switching regulators. * **Telecommunications:** Used in line filters to prevent interference. --- ### 4. Physical Construction The part is generally constructed with a wire winding around a magnetic core, then encapsulated in a protective sleeve (often polyolefin or flame-retardant epoxy). ```text Structure: [Lead Wire] --- [Molded/Protected Body (Inductor)] --- [Lead Wire] (10µH Coil Inside) ```
