The **PIT03012-R68** is a high-current, shielded surface-mount (SMD) power inductor. This component is widely used in power management circuits, specifically in DC-DC converters to store energy and filter noise. ### Technical Specifications Below are the typical electronic characteristics for this specific part number: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.68 µH | | **Tolerance** | ±20% | | **Case Size** | 0312 (approx. 3.0 x 3.0 x 1.2 mm) | | **DC Resistance (DCR)** | ~18-25 mΩ (Typical) | | **Saturation Current (Isat)** | ~4.5A - 6.0A (Varies by manufacturer) | | **Operating Temperature** | -40°C to +125°C | | **Shielding** | Magnetically Shielded | --- ### Core Electronic Features #### 1. Low Inductance Value (0.68 µH) With an inductance of 0.68 microhenries, this part is designed for **high-frequency switching power supplies**. Lower inductance values allow for faster transient response times and are ideal for modern processors and mobile devices. #### 2. Magnetic Shielding The "shielded" construction means the magnetic flux is contained within the component body. This is critical for: * **EMI Reduction:** Minimizing electromagnetic interference with nearby sensitive components. * **High-Density PCB Layouts:** Allowing components to be placed closer together without cross-talk. #### 3. Low Profile Design The "12" in the suffix usually refers to a height of **1.2 mm**. This makes it an "ultra-low profile" component, essential for thin electronics like smartphones, tablets, and wearable technology. #### 4. High Saturation Current Despite its small footprint, it is engineered to handle high peak currents without the core "saturating" (losing its inductive properties). This ensures stable performance during heavy power loads. --- ### Common Applications * **DC-DC Converters:** Buck, Boost, and Buck-Boost regulators. * **Mobile Devices:** Power management units (PMICs) for smartphones. * **Computing:** Graphics cards and SSD power rails. * **IoT Sensors:** Efficient power conversion for battery-operated devices. ---
