The **LPAU-141MA-R** is a specific surface-mount (SMT) power inductor manufactured by **Cyntec**. It belongs to a category of high-performance, metal-alloy molded power inductors designed for modern power management circuits. --- ### ## Technical Specifications Below are the typical technical parameters for this specific part series: | Parameter | Description / Value | | :--- | :--- | | **Manufacturer** | Cyntec | | **Component Type** | Molded Power Inductor | | **Material** | Metal Alloy Powder | | **Inductance** | 0.14 µH (Typical for the 141 series) | | **Tolerance** | ±20% | | **Structure** | Shielded (Magnetic) | | **Operating Temp** | -55°C to +125°C | --- ### ## Key Features 1. **Low Profile Design:** The "LPAU" prefix indicates a low-profile architecture, making it suitable for compact electronics like smartphones, tablets, and thin laptops. 2. **Metal Alloy Core:** Unlike traditional ferrite cores, the metal alloy construction provides a "soft" saturation characteristic. This means the inductance drops gradually as current increases, preventing sudden circuit failure. 3. **High Efficiency:** It is designed with low DC Resistance (DCR) and low AC loss, which minimizes heat generation and maximizes battery life in portable devices. 4. **Magnetic Shielding:** The molded construction naturally shields the component, reducing Electromagnetic Interference (EMI) with neighboring components on the PCB. --- ### ## Applications The LPAU-141MA-R is primarily used in **DC-DC Converter** applications, specifically: * **Point of Load (POL) Converters:** Used in CPUs and GPUs for power regulation. * **Voltage Regulator Modules (VRM):** Common in high-end computing. * **Mobile Devices:** Powering internal chipsets where space is at a premium. --- ### ## Equivalent/Alternative Parts If you are sourcing this part, you might look for alternatives from these series: * **Vishay:** IHLP series. * **TDK:** SPM series. * **Murata:** DFE series.
