The **CMLS104T-R56MS** is a high-performance, surface-mount (SMD) power inductor commonly manufactured by **Cyntec**. It belongs to the CMLS series, which is characterized by its molded construction and high current handling capabilities. --- ### 1. Technical Specifications Below are the primary electrical and physical characteristics of the component: | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.56 µH | | **Tolerance** | ±20% (indicated by 'M') | | **DC Resistance (DCR)** | ~1.6 mΩ (Typical) / 1.8 mΩ (Max) | | **Saturation Current (Isat)** | ~25A - 30A (Inductance drop of 30%) | | **Heating Current (Irms)** | ~20A - 23A (Temp rise of 40°C) | | **Operating Temperature** | -55°C to +125°C | | **Case Size** | 104T (approx. 11.5 x 10.3 x 4.0 mm) | --- ### 2. Part Number Breakdown Understanding the nomenclature helps in identifying variants: * **CMLS**: Series name (Molded Power Inductor). * **104T**: Dimensional code (approx. 10mm x 10mm footprint, 4mm height). * **R56**: Inductance value (R56 = 0.56 microhenries). * **M**: Tolerance (M = ±20%). * **S**: Special code/standard internal suffix. --- ### 3. Key Electronic Features * **Magnetic Shielding:** The molded iron powder construction provides excellent magnetic shielding, minimizing electromagnetic interference (EMI) with surrounding components. * **Soft Saturation:** Unlike ferrite core inductors, this molded type exhibits a "soft" saturation curve, meaning it retains better inductance stability even when the current exceeds the rated limits. * **Low DCR:** The use of flat wire or heavy gauge copper minimizes DC resistance, reducing power loss and heat generation. * **High Frequency Performance:** Designed to operate efficiently in high-frequency switching power supplies (DC-DC converters). --- ### 4. Common Applications This inductor is typically found in high-current power stages for: 1. **Motherboards & Servers:** CPU/GPU voltage regulator modules (VRM). 2. **DC-DC Converters:** Point-of-load (POL) power supplies. 3. **Laptops:** High-efficiency power management systems. 4. **Battery Powered Devices:** Where high efficiency and compact size are critical.
