The **CTMPH100805F-R24M** is a high-performance **surface-mount (SMD) power inductor** typically used in DC-DC converters and power management modules. This specific part belongs to the "Molded" category, meaning it is designed for high current density and low acoustic noise. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical specifications: | Segment | Meaning | Specification | | :--- | :--- | :--- | | **CTMPH** | Series | Molded Power Inductor (High Saturation) | | **100805** | Dimensions | Approx. 1.0mm x 0.8mm x 0.5mm (Metric) | | **F** | RoHS Status | Lead-Free / Compliant | | **-R24** | Inductance | 0.24 µH (R denotes decimal) | | **M** | Tolerance | ±20% | --- ### 2. Key Electrical Characteristics This component is engineered for efficiency in compact spaces. Below are the typical performance ratings for this specific value: * **Inductance:** 0.24 µH * **DC Resistance (DCR):** Extremely low, usually measured in mΩ (milliohms) to minimize power loss. * **Saturation Current ($I_{sat}$):** The current level where inductance drops by a specific percentage (usually 30%). For this size, it is optimized for high peaks. * **Heating Current ($I_{rms}$):** The continuous current that causes a specific temperature rise (usually 40°C). --- ### 3. Technical Features * **Shielded Construction:** The molded metal powder body provides magnetic shielding, which significantly reduces EMI (Electromagnetic Interference). * **Low Profile:** The "05" height (0.5mm) makes it ideal for ultra-thin electronics like smartphones and wearables. * **High Frequency:** Designed to operate efficiently in high-switching frequency environments (up to several MHz). --- ### 4. Typical Applications This part is commonly found in the following circuits: 1. **Mobile Devices:** Power rails for CPUs and GPUs in smartphones. 2. **DC-DC Converters:** Buck or Boost converters in point-of-load (POL) modules. 3. **IoT Sensors:** Where small footprint and high efficiency are critical for battery life. ---
