The **CSEB0630-R56M** is a high-current, surface-mount (SMD) power inductor commonly used in DC-DC converters and power supply modules. It belongs to the "Molded Power Inductor" category, known for its compact size and high efficiency. --- ### ## Technical Specifications Below are the primary electrical and physical parameters for this specific component: | Parameter | Value / Specification | | :--- | :--- | | **Inductance** | 0.56 µH | | **Tolerance** | ±20% (indicated by the 'M' suffix) | | **DC Resistance (DCR)** | ~3.0 mΩ (Typical) / ~3.6 mΩ (Max) | | **Saturation Current (Isat)** | ~18.0 A to 22.0 A | | **Heat Rating Current (Irms)** | ~13.0 A to 15.0 A | | **Case Size** | 0630 (approx. 7.0 x 6.6 x 3.0 mm) | | **Operating Temperature** | -40°C to +125°C | --- ### ### Key Features 1. **Magnetic Shielding:** The part is molded with a metal alloy powder, which provides excellent magnetic shielding. This reduces Electromagnetic Interference (EMI) with neighboring components on the PCB. 2. **High Saturation:** Unlike traditional ferrite core inductors, molded inductors handle high-current transients without a sharp drop in inductance. 3. **Low DCR:** The use of thick copper wire ensures very low DC resistance, which minimizes power loss and heat generation during operation. 4. **Compact Footprint:** The "0630" designation refers to its dimensions (6mm x 6mm base area, 3mm height), making it ideal for high-density electronic assemblies. --- ### ### Part Number Breakdown Understanding the nomenclature helps in identifying similar components: * **CSEB**: Series series code (Molded Power Inductor). * **0630**: Dimensions (Width/Length = ~6mm, Height = 3.0mm). * **R56**: Inductance value. 'R' acts as a decimal point (0.56 microhenries). * **M**: Tolerance code (M = ±20%). --- ### ### Common Applications * **Voltage Regulator Modules (VRM):** Used in motherboards and servers. * **DC-DC Converters:** Point-of-Load (POL) power supplies. * **Consumer Electronics:** Laptops, tablets, and high-performance gaming consoles. * **Battery Powered Devices:** Due to high efficiency and low energy waste.
