The **0624CDMCCDS-R08MC** is a high-performance, surface-mount (SMD) power inductor. It is part of the CDMCCDS series, which is specifically designed for high-current power supply applications, such as DC/DC converters. ### 1. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical characteristics: | Component | Code | Meaning | | :--- | :--- | :--- | | **Series** | CDMCCDS | Metal compound molded power inductor | | **Size** | 0624 | Approx. 7.0 x 6.6 mm footprint, 2.4 mm height | | **Inductance** | R08 | 0.082 microhenries (µH) | | **Tolerance** | M | ±20% | | **Packaging** | C | Carrier Tape (Taped and Reeled) | --- ### 2. Key Technical Specifications These specs determine how the part performs under electrical load: * **Inductance:** 0.082 µH (Measured at 100kHz). * **DC Resistance (DCR):** Extremely low, typically around **0.70 mΩ** (Max 0.84 mΩ). This minimizes power loss and heat generation. * **Saturation Current ($I_{sat}$):** The current at which inductance drops by 30%. For this part, it is typically **42.0 Amperes**. * **Temperature Rise Current ($I_{rms}$):** The current that causes a 40°C temperature rise. Typically around **29.0 Amperes**. * **Operating Temperature:** -55°C to +125°C (including self-heating). --- ### 3. Construction and Features The 0624CDMCCDS series uses a specific manufacturing process to achieve its high-density performance: 1. **Metal Powder Molding:** The coil is embedded in a metallic magnetic powder. This creates a "shielded" structure that reduces EMI (Electromagnetic Interference) and prevents acoustic noise (buzzing). 2. **Soft Saturation:** Unlike ferrite inductors that lose inductance sharply, this metal-molded type has a "soft" saturation curve, making the circuit more stable under peak loads. 3. **Low Profile:** At only 2.4mm height, it is ideal for thin electronic devices like laptops and tablets. --- ### 4. Common Applications Due to its high current handling and low DCR, this inductor is used in: * **Voltage Regulator Modules (VRMs):** For CPUs and GPUs. * **DC/DC Converters:** Point-of-load (POL) power supplies. * **Battery Powered Devices:** Where high efficiency is required to save battery life. * **SSD Power Rails:** Providing clean power to high-speed memory controllers. ---
