The **CMLE041B-R56MS** is a high-performance, low-profile power inductor, typically manufactured by **Cyntec**. This component belongs to the category of "Molded Power Inductors," which are designed for high-current applications in compact electronic devices. --- ### 1. Technical Specifications The part number itself contains the core technical data. Below is a breakdown of its primary specifications: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.56 µH (Microhenries) | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR) Max** | ~8.0 mΩ to 10.0 mΩ (Typical) | | **Saturation Current (Isat)** | ~11A to 14A (approximate range) | | **Temperature Rise Current (Irms)** | ~9A to 11A (approximate range) | | **Case Size** | 041B (approx. 4.0 x 4.0 x 1.2 mm) | | **Operating Temperature** | -55°C to +125°C | --- ### 2. Key Features * **Molded Construction:** The inductor uses a metal powder core molded around the coil. This design provides excellent magnetic shielding and minimizes audible noise (buzzing). * **High Current Handling:** Despite its small footprint, the metal alloy powder allows for a high saturation current, meaning the inductance doesn't drop sharply as current increases. * **Low Profile:** The "1B" or "1.2" height suffix usually indicates a very slim profile, making it ideal for thin devices like smartphones or tablets. * **Low DCR:** The use of thick flat or round copper wire reduces resistance, which improves efficiency and reduces heat generation. --- ### 3. Common Applications This specific inductor is primarily used in DC-DC converters for power management. Typical devices include: 1. **Mobile Electronics:** Smartphones, tablets, and wearables. 2. **Computing:** Laptops, SSDs (Solid State Drives), and graphics cards. 3. **IoT Devices:** Small sensors or modules requiring efficient power regulation. --- ### 4. Comparison to Standard Inductors Compared to traditional ferrite core inductors, the **CMLE series** offers: * **Soft Saturation:** It handles current spikes better without a total loss of inductance. * **Space Savings:** Higher energy density per cubic millimeter. * **Ruggedness:** The molded body protects the internal coil from physical vibration and environmental factors.
