The **PIT04020-R68M** is a high-current, shielded power inductor typically used in DC-DC converter applications. Below is a detailed breakdown of its specifications and electronic characteristics. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical constraints of the component: | Segment | Meaning | Description | | :--- | :--- | :--- | | **PIT** | Series Type | Power Inductor (Thin/High Current) | | **04020** | Physical Size | Approx. 4.0mm x 4.0mm x 2.0mm | | **R68** | Inductance Value | 0.68 µH (Microhenries) | | **M** | Tolerance | ±20% | --- ### 2. Key Technical Specifications While exact values can vary slightly by manufacturer (such as Cyntec or Sunlord), the standard parameters for a 04020-R68M are generally: * **Inductance:** 0.68 µH * **DC Resistance (DCR):** Usually very low (approx. 10mΩ to 20mΩ) to minimize power loss. * **Saturation Current (Isat):** The current at which inductance drops (typically 7A – 11A). * **Heating Current (Irms):** The current that causes a 40°C temperature rise (typically 6A – 9A). * **Operating Temperature:** -40°C to +125°C (including self-heating). --- ### 3. Core Features & Construction 1. **Shielded Construction:** The inductor is magnetically shielded, which reduces Electromagnetic Interference (EMI) and prevents the magnetic field from affecting nearby sensitive components. 2. **Metal Alloy Powder Core:** Unlike traditional ferrite cores, these use a metal composite core. This allows for: * **Soft Saturation:** The inductance drops gradually rather than abruptly when current increases. * **High Power Density:** Large current handling in a small SMT (Surface Mount Technology) footprint. 3. **Low Profile:** The "20" in the part number indicates a 2.0mm height, making it ideal for slim devices like smartphones or laptops. --- ### 4. Common Applications This part is designed for high-efficiency power regulation: * **Voltage Regulator Modules (VRM):** Used in CPU/GPU power stages. * **DC-DC Converters:** Buck, Boost, or Buck-Boost converters. * **Consumer Electronics:** Tablets, SSDs, and handheld gaming consoles. * **Automotive Electronics:** Infotainment systems and ADAS sensors. ---
