Key Specifications The following table highlights the primary electrical and physical characteristics of this component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.47 µH | | **Tolerance** | ±20% (M) | | **DC Resistance (DCR)** | ~5.3 mΩ (Max) | | **Saturation Current (Isat)** | ~18.5 A | | **Temperature Rise Current (Irms)** | ~13.0 A | | **Case Size (Metric)** | 0624 (approx. 7.3 x 6.7 x 2.4 mm) | | **Operating Temperature** | -55°C to +125°C | --- ### 2. Component Features * **Metal Composite Core:** Unlike traditional ferrite inductors, this part uses a metal powder core. This provides a "soft saturation" characteristic, meaning the inductance drops gradually rather than abruptly when the current increases. * **Low Profile:** With a height of approximately 2.4 mm, it is ideal for space-constrained PCB designs. * **Shielded Construction:** The molded design inherently provides magnetic shielding, reducing Electromagnetic Interference (EMI) with neighboring components. * **High Efficiency:** The low DCR (Direct Current Resistance) minimizes power loss due to heat, making it efficient for high-current applications. --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying variations: | Segment | Meaning | | :--- | :--- | | **0624** | Size dimensions (approx. 6mm width, 2.4mm height) | | **CDMC** | Product series (Molded Metal Inductor) | | **R47** | Inductance value (R47 = 0.47 µH) | | **M** | Tolerance (M = ±20%) | | **C** | Packaging/Internal Code | --- ### 4. Common Applications This inductor is typically used in DC-DC converter circuits for: * **Computing:** Laptops, servers, and graphic cards (VRM modules). * **Mobile Devices:** Battery-powered equipment requiring high efficiency. * **Automotive/Industrial:** Distributed power systems where EMI suppression is critical.
