The **FDVE0630-H-R33M** is a high-current, shielded power inductor manufactured by **Murata Electronics** (formerly Toko). It is designed primarily for DC-DC converter applications where space is limited and efficiency is critical. --- ### 1. Technical Specifications Below are the key electrical and physical parameters for the component: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.33 µH | | **Tolerance** | ±20% | | **Rated Current (Isat)** | 22.0 A (Saturation) | | **Rated Current (Itemp)** | 16.0 A (Temperature Rise) | | **DC Resistance (DCR)** | 2.1 mΩ (Max) | | **Operating Temperature** | -40°C to +125°C | | **Package / Case** | 2524 (6.3mm x 6.0mm x 3.0mm) | | **Shielding** | Shielded (Metal Alloy Core) | --- ### 2. Key Features & Construction * **Metal Alloy Core:** Unlike traditional ferrite inductors, this part uses a metal alloy powder core. This provides "soft saturation" characteristics, meaning the inductance drops gradually rather than abruptly as current increases. * **Magnetic Shielding:** The construction minimizes Electromagnetic Interference (EMI), making it suitable for high-density PCB layouts near sensitive components. * **Low DCR:** The extremely low DC resistance (2.1mΩ) minimizes power loss due to heat, significantly increasing the efficiency of power supplies. * **AEC-Q200 Qualified:** Often used in automotive applications due to its high reliability and resistance to thermal shock and vibration. --- ### 3. Common Applications This inductor is typically found in high-frequency switching regulators, specifically: 1. **CPU/GPU Power Supplies:** Used in VRMs (Voltage Regulator Modules) for servers and laptops. 2. **Automotive Electronics:** Infotainment systems, ADAS, and ECU power rails. 3. **Telecom Infrastructure:** High-efficiency DC-DC converters in base stations. 4. **Battery Powered Devices:** Where high peak currents are required in a small form factor. --- ### 4. Footprint and Mounting The device uses an **SMD (Surface Mount Device)** landing pattern. The "0630" in the part number refers to its dimensions: * **Length:** 6.3 mm * **Width:** 6.0 mm * **Height:** 3.0 mm
