The **CMLB063T-R10MS** is a high-performance, surface-mount (SMD) power inductor commonly used in DC-DC converters and power supply modules. It belongs to the **CMLB series** manufactured by **Cyntec**. --- ## 1. Part Number Breakdown Understanding the alphanumeric code helps identify its specific electrical characteristics: | Component | Code | Description | | :--- | :--- | :--- | | **Series** | CMLB063T | High-current molded power inductor (063 size) | | **Inductance** | R10 | 0.10 µH (Microhenries) | | **Tolerance** | M | ±20% | | **Special Code** | S | Standard/Internal control code | --- ## 2. Technical Specifications This inductor is designed for high-frequency applications where low energy loss and high current handling are critical. ### Electrical Characteristics * **Inductance:** 0.10 µH * **DC Resistance (DCR):** Typically very low (approx. 0.9mΩ to 1.2mΩ) to minimize heat dissipation. * **Saturation Current ($I_{sat}$):** The current level where inductance drops by 30%. For this part, it is typically around **35A - 50A** (depending on specific revision). * **Rated Current ($I_{rms}$):** The continuous current that causes a 40°C temperature rise. Typically around **25A - 32A**. * **Operating Temperature:** -55°C to +125°C. ### Physical Dimensions (063T Size) The "063" refers to the footprint size, roughly following these metrics: * **Length:** ~7.0 mm * **Width:** ~6.6 mm * **Height:** ~3.0 mm --- ## 3. Key Features * **Molded Construction:** The coil is encapsulated in a metal powder composite. This provides excellent magnetic shielding and reduces acoustic noise (buzzing). * **Soft Saturation:** Unlike ferrite core inductors, the inductance drops gradually as current increases, preventing sudden circuit failures. * **Low DCR:** The use of flat wire or heavy-gauge copper ensures minimal power loss through heat. --- ## 4. Typical Applications Due to its low inductance and high current capability, the CMLB063T-R10MS is ideal for: 1. **CPU/GPU Voltage Regulators:** Used in "Multi-phase" power designs for laptops and servers. 2. **Point of Load (POL) Converters:** High-efficiency DC-DC step-down conversion. 3. **High-Density Power Supplies:** Where board space is limited but power requirements are high. ---
