The **CMLB063T-R22MS** is a high-current, low-profile power inductor manufactured by **Cyntec**. It belongs to the CMLB series, which is designed using metal powder molding technology to provide high efficiency and high density for power conversion circuits. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and electrical characteristics: | Parameter | Value | Description | | :--- | :--- | :--- | | **Inductance** | 0.22 µH | The nominal inductance value. | | **Tolerance** | ±20% (M) | Deviation range from the nominal value. | | **DC Resistance (DCR)** | ~3.1 mΩ (Max) | Internal resistance; lower is better for efficiency. | | **Isat (Saturation Current)** | ~25A - 30A | The current at which inductance drops by 30%. | | **Irms (Rated Current)** | ~18A - 22A | The current that causes a 40°C temperature rise. | | **Size Code** | 063T | Approx. 7.1 x 6.6 x 3.0 mm. | --- ### 2. Key Features and Construction * **Molded Body:** The inductor is made by compressing metal powder around a copper coil. This creates a "shielded" structure that naturally reduces Electromagnetic Interference (EMI). * **Soft Saturation:** Unlike ferrite core inductors that lose inductance sharply, this metal powder core exhibits "soft saturation," meaning it maintains performance even under high current spikes. * **Low DCR:** The use of thick flat or round wire minimizes energy loss as heat, making it ideal for high-efficiency DC-DC converters. * **Frequency Range:** Optimized for high-frequency switching power supplies (typically up to 2MHz+). --- ### 3. Common Applications This specific component is usually found in high-demand power stages: 1. **Voltage Regulator Modules (VRM):** Used in CPU and GPU power delivery on motherboards and graphics cards. 2. **DC-DC Converters:** Point-of-Load (POL) converters for telecommunications and industrial equipment. 3. **Battery Powered Devices:** High-efficiency power management in laptops and tablets. 4. **Automotive:** Infotainment and ADAS systems where compact size and high reliability are required. --- ### 4.
