## Technical Overview: CTMPC100804F-R24M The **CTMPC100804F-R24M** is a high-performance, surface-mount (SMD) molded power inductor. It is designed specifically for high-current applications where space is limited and efficiency is critical, such as DC-DC converters. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the physical and electrical characteristics: | Code Segment | Meaning | Specification | | :--- | :--- | :--- | | **CTMPC** | Series Name | Molded Power Inductor (Composite Core) | | **100804** | Case Size | ~1.0mm x 0.8mm x 0.4mm (Compact) | | **F** | Lead-Free | RoHS Compliant / Environmental Standard | | **R24** | Inductance Value | 0.24 µH (Microhenries) | | **M** | Tolerance | ±20% | --- ### 2. Key Electrical Specifications Based on the standard parameters for this series, here are the technical limits: * **Inductance:** 0.24 µH * **DC Resistance (DCR):** Extremely low, typically optimized to minimize power loss. * **Isat (Saturation Current):** The current level where inductance drops by a specific percentage (usually 30%). Molded inductors feature "soft saturation." * **Irms (Heating Current):** The continuous current that causes a 40°C temperature rise. * **Operating Temperature:** Typically -40°C to +125°C. --- ### 3. Core Technology: Molded Construction Unlike traditional wire-wound inductors with an open core, the **CTMPC series** uses a metal powder molding technology: 1. **Magnetic Shielding:** The metal powder surrounds the coil, inherently shielding the component and reducing Electromagnetic Interference (EMI). 2. **High Current Density:** The composite core handles higher peak currents without sudden saturation compared to ferrite cores. 3. **Mechanical Ruggedness:** The solid molded body provides excellent resistance to vibration and thermal shock. --- ### 4. Common Applications This specific part is ideal for high-density electronic environments: * **Smartphones & Tablets:** Power management modules (PMIC). * **Wearables:** Due to its ultra-low profile (0.4mm height). * **SSD/Storage:** Localized voltage regulation for high-speed data chips. * **IoT Devices:** Where battery life depends on high-efficiency power conversion. ---
