The **CTMPH060303F-R24M** is a high-performance, surface-mount (SMD) power inductor. This specific component is part of the **molded power inductor** family, designed for high-density power applications such as smartphones, tablets, and DC-DC converters. --- ### 1. Part Number Breakdown The nomenclature reveals the key physical and electrical characteristics of the part: | Segment | Meaning | Detail | | :--- | :--- | :--- | | **CTMPH** | Series Prefix | Metal Alloy Molded Power Inductor | | **060303** | Dimensions | Metric size (approx. 1.6 x 0.8 x 0.8 mm) | | **F** | Lead-Free | RoHS Compliant / Halogen Free | | **R24** | Inductance Value | **0.24 µH** (R denotes the decimal point) | | **M** | Tolerance | **±20%** | --- ### 2. Technical Specifications Molded inductors use a metallic powder core, which offers superior performance in high-frequency environments compared to traditional ferrite cores. * **Inductance:** 0.24 µH * **DC Resistance (DCR):** Typically very low (measured in mΩ) to minimize power loss. * **Saturation Current ($I_{sat}$):** The current level where inductance drops by a specific percentage (usually 30%). Molded cores have a "soft" saturation characteristic. * **Operating Temperature:** Generally rated from -40°C to +125°C. * **Construction:** Iron powder molding technology which provides magnetic shielding and reduces acoustic noise. --- ### 3. Key Advantages 1. **High Current Density:** Capable of handling higher currents relative to its small footprint. 2. **Magnetic Shielding:** The molded construction naturally shields the component, reducing Electromagnetic Interference (EMI) with neighboring components. 3. **Stability:** High stability against temperature fluctuations and physical vibration. 4. **Efficiency:** Low DCR ensures minimal energy is wasted as heat, extending battery life in portable devices. --- ### 4. Typical Applications The CTMPH060303F-R24M is commonly found in: * **DC-DC Converters:** Point-of-load (POL) power supplies. * **Mobile Devices:** Power management ICs (PMICs) for CPUs and GPUs. * **IoT Modules:** Compact wireless sensors requiring efficient power regulation.
