The **CMLB063T-R20MS** is a high-performance, low-profile power inductor manufactured by **Cyntec**. It belongs to the CMLB series, which is designed specifically for high-current power supplies and DC-DC converters in compact electronic devices. --- ## 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and electrical characteristics. | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.20 µH (Microhenries) | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR)** | ~1.6 mΩ (Typical) / 1.9 mΩ (Max) | | **Saturation Current (Isat)** | ~25.0 A | | **Heating Current (Irms)** | ~20.0 A | | **Case Size** | 063T (Approx. 7.3 x 6.6 x 3.0 mm) | | **Operating Temperature** | -55°C to +125°C | --- ## 2. Key Features and Construction The CMLB series utilizes advanced material science to achieve high efficiency in small footprints. * **Metal Powder Core:** Unlike traditional ferrite inductors, this part uses a molded metal powder core. This provides a **soft saturation characteristic**, meaning the inductance drops gradually rather than abruptly when current increases. * **Magnetic Shielding:** The molded construction naturally shields the component, minimizing Electromagnetic Interference (EMI) with surrounding components on the PCB. * **Low DCR:** The extremely low DC resistance minimizes power loss through heat, making it ideal for high-efficiency battery-operated devices. --- ## 3. Typical Applications The CMLB063T-R20MS is commonly found in circuits requiring high current and high switching frequencies. 1. **Voltage Regulator Modules (VRMs):** Used in CPU and GPU power delivery. 2. **DC-DC Converters:** Buck, Boost, and Buck-Boost topologies. 3. **Portable Electronics:** Smartphones, tablets, and laptops where board space is limited. 4. **Automotive Infotainment:** Compact power modules for in-car displays and sensors. --- ## 4. Footprint Dimensions (Approximate) The "063T" designation refers to the physical dimensions of the SMD (Surface Mount Device) package. | Dimension | Measurement (mm) | | :--- | :--- | | **Length (L)** | 7.3 ± 0.3 | | **Width (W)** | 6.6 ± 0.3 | | **Height (T)** | 3.0 (Max) | ---
