The **TPQH201610TF-R24M-R** is a high-performance power inductor, typically used in power management circuits for mobile devices, tablets, and compact electronics. It belongs to the category of **Molded Power Inductors**. --- ### 1. Part Number Breakdown Understanding the alphanumeric code helps identify the component's physical and electrical properties: | Segment | Code | Meaning | | :--- | :--- | :--- | | **Series** | TPQH | High-current, low-profile molded inductor series | | **Dimensions** | 201610 | Size: 2.0mm (L) x 1.6mm (W) x 1.0mm (H) | | **Material** | TF | Specialized core material (often Metal Alloy) | | **Inductance** | R24 | 0.24 microhenries ($\mu H$) | | **Tolerance** | M | $\pm$20% tolerance | | **Packaging** | -R | Tape and Reel (RoHS compliant) | --- ### 2. Key Technical Specifications While exact values can vary slightly by manufacturer (such as Tai-Tech or Sunlord), the standard specs for an R24M in this footprint are: * **Inductance:** 0.24 $\mu H$ * **DC Resistance (DCR):** Extremely low (typically between 15m$\Omega$ to 25m$\Omega$). * **Saturation Current ($I_{sat}$):** High (approx. 5.0A to 6.5A) — the current at which inductance drops by 30%. * **Heat Rating Current ($I_{rms}$):** Approx. 4.0A to 5.0A — the current that causes a 40°C temperature rise. * **Operating Temperature:** -40°C to +125°C. --- ### 3. Core Features & Construction 1. **Metal Alloy Molding:** Unlike traditional wire-wound inductors with a ferrite core, this uses a metallic powder pressed around the coil. This prevents "hard saturation" (where inductance drops instantly) and provides a "soft saturation" curve. 2. **Magnetic Shielding:** The molded construction naturally shields the component, reducing Electromagnetic Interference (EMI) with surrounding components. 3. **High Current Density:** Its small 2016 (0806 inch) footprint can handle significantly higher current than standard multilayer inductors. --- ### 4. Typical Applications This component is used in **DC-DC Converter circuits**, specifically: * **Point of Load (POL) Converters:** Providing power to CPUs or GPUs. * **Smartphone PMICs:** Power Management Integrated Circuits. * **SSD/Flash Memory:** Powering high-speed data storage units. ---
