The **CMLS063T-R82MS** is a high-performance, surface-mount (SMD) power inductor manufactured by **Cyntec**. It belongs to the CMLS series, which is characterized by its metal-molded construction designed for high-current applications and excellent electromagnetic interference (EMI) shielding. --- ### 1. Technical Specifications The part number contains specific data regarding its physical and electrical properties: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.82 µH | | **Tolerance** | ±20% (M) | | **Case Size** | 063T (approx. 7.3 x 6.6 x 3.0 mm) | | **DC Resistance (DCR)** | ~5.3 mΩ (Typ) / 6.0 mΩ (Max) | | **Saturation Current (Isat)** | ~17.0 A (Typical drop of 30%) | | **Rated Current (Irms)** | ~13.0 A (Typical temp rise of 40°C) | | **Operating Temperature** | -55°C to +125°C | --- ### 2. Key Features * **Metal Powder Core:** Uses a composite metal iron powder which allows for "soft saturation" characteristics (the inductance drops gradually rather than abruptly when current increases). * **Magnetic Shielding:** The molded construction naturally shields the component, reducing leakage flux and interference with neighboring components. * **Low DCR:** The use of flat or thick copper wire minimizes power loss due to heat, making it highly efficient. * **High Reliability:** Designed to handle high transient current spikes without core saturation. --- ### 3. Part Number Breakdown The nomenclature can be decoded as follows: | Code | Meaning | | :--- | :--- | | **CMLS** | Series Name (Cyntec Molded Low Profile Inductor) | | **063T** | Dimensions (06 = ~6mm width, 3T = ~3mm height) | | **R82** | Inductance Value (R82 = 0.82 Microhenries) | | **M** | Tolerance (M = ±20%) | | **S** | Internal Code / Standard series | --- ### 4. Common Applications This inductor is typically used in DC-DC converters for power management in: * **Computing:** Laptops, servers, and graphics cards (GPU power stages). * **Mobile Devices:** High-efficiency power modules for smartphones and tablets. * **Automotive/Industrial:** Point-of-Load (POL) converters where space is limited but current demands are high.
