The **CSCM1260-R80M** is a high-performance **Surface Mount (SMD) Power Inductor**, typically utilized in power management circuits. It belongs to a category of high-current, molded inductors designed for stability in harsh environments. --- ### 1. Technical Specifications The part number follows a specific nomenclature that describes its physical and electrical characteristics: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Inductance** | 0.80 µH | Rated at 100kHz, 1V | | **Tolerance** | ±20% | Standard deviation for power inductors (M code) | | **DC Resistance (DCR)** | ~1.5 mΩ - 2.5 mΩ | Varies by manufacturer (Typ/Max) | | **Isat (Saturation Current)** | ~25A - 35A | Current where inductance drops by 20-30% | | **Irms (Heating Current)** | ~20A - 25A | Current causing a 40°C temperature rise | | **Package Size** | 1260 | Approx. 13.5 x 12.5 x 6.0 mm | --- ### 2. Physical Construction The "CSCM" series is generally built using a **Molded Magnetic Metal Alloy** technique. * **Core Material:** Iron powder or composite alloy. This allows for a "soft saturation" characteristic, meaning the inductor doesn't lose its properties abruptly when the current spikes. * **Shielding:** The molded design provides inherent magnetic shielding, which minimizes Electromagnetic Interference (EMI) with neighboring components. * **Terminals:** Lead-free (RoHS compliant) construction with robust solder pads for high-vibration environments. --- ### 3. Key Features and Applications The CSCM1260-R80M is engineered for high-efficiency power conversion. #### Key Features: * **Low DCR:** Minimizes copper losses, leading to higher efficiency. * **High Frequency Range:** Capable of operating in switching frequencies up to 5MHz. * **Thermal Stability:** Designed to operate in temperatures ranging from -40°C to +125°C. #### Common Applications: 1. **Voltage Regulator Modules (VRM):** Used in CPU/GPU power delivery for servers and laptops. 2. **DC/DC Converters:** Point-of-load (POL) converters in telecommunications. 3. **Automotive:** Infotainment systems and LED lighting drivers. 4. **Battery Powered Devices:** High-current power supplies where space and efficiency are critical. --- ### 4. Comparison with Standard Wire-Wound Inductors Compared to traditional unshielded wire-wound inductors, the CSCM1260-R80M offers: 1. **Higher Current Density:** More power in a smaller footprint. 2. **Lower Acoustic Noise:** The molded construction reduces "coil whine" caused by magnetostriction. 3. **Better EMI Performance:** Integrated shielding prevents flux leakage.
