Breakdown of the Part Number Understanding the nomenclature helps in identifying its specific features: * **VLS**: Series Name (Wound Ferrite) * **2016**: Dimensions (2.0mm Length x 1.6mm Width) * **12**: Height (1.2mm Max) * **HBX**: Internal characteristic code (High-current metal-core type) * **R33**: Inductance value (R33 = 0.33 µH) * **M**: Tolerance (±20%) * **1**: Internal suffix/Packaging code --- ### 3. Structural & Performance Features * **Metal Core Technology:** Unlike standard ferrite inductors, the HBX series uses a metallic magnetic material. This allows for higher current handling (Saturation Current) in a smaller footprint. * **Magnetic Shielding:** The coil is encapsulated in a magnetic resin. This minimizes Electromagnetic Interference (EMI) with surrounding components on the PCB. * **High Efficiency:** The low DC resistance (DCR) reduces power loss, making it ideal for battery-operated devices where thermal management is critical. --- ### 4. Typical Applications This inductor is commonly found in space-constrained, high-efficiency power modules: * **Smartphones & Tablets:** DC-DC converter circuits for CPUs and GPUs. * **Wearables:** Power management for smartwatches and fitness trackers. * **IoT Modules:** Compact wireless communication modules. * **HDDs/SSDs:** Local power supply filtering. ---
