The **WPT-6B2-R** is a high-performance, shielded power inductor manufactured by **Wurth Elektronik** (part of the WE-PD series). These components are primarily designed for DC/DC converters and power management circuits where efficiency and low electromagnetic interference (EMI) are critical. --- ### ## Technical Specifications The "6B2" designation usually refers to the specific package size and core material within the product series. Below are the typical characteristics of the WPT-6B2-R series: | Parameter | Typical Value / Description | | :--- | :--- | | **Component Type** | Shielded Power Inductor | | **Mounting Type** | Surface Mount (SMD/SMT) | | **Inductance Range** | 1.0 µH to 1000 µH (varies by sub-model) | | **Current Rating** | High Saturation Current (up to several Amperes) | | **Operating Temp** | -40°C to +125°C | | **Shielding** | Magnetic Shielding (minimizes EMI) | --- ### ### Key Electronic Components & Construction 1. **Ferrite Core:** The part uses a high-grade ferrite material which provides high magnetic permeability and low core losses at high switching frequencies. 2. **Magnetic Shielding:** The "Shielded" nature means the winding is encased in a magnetic material. This prevents the magnetic field lines from escaping and interfering with neighboring sensitive components on the PCB. 3. **Winding:** Constructed with high-quality copper wire to ensure low **DCR (DC Resistance)**. Low DCR is essential for minimizing heat generation and maximizing battery life in portable electronics. 4. **Terminal Pads:** The base features robust solder pads designed for reflow soldering, providing strong mechanical stability and reliable electrical connection. --- ### ### Common Applications The WPT-6B2-R is commonly integrated into the following circuits: * **Switching Regulators:** Used as the energy storage element in Buck, Boost, and SEPIC converters. * **Power Supplies:** Found in laptop adapters, industrial power bricks, and LED drivers. * **Filtering:** Acting as a low-pass filter to smooth out ripple current in power rails. * **Embedded Systems:** Powering microcontrollers (MCUs) and FPGAs where stable voltage is required. --- ### ### Advantages * **High Power Density:** Large current handling capability relative to its small physical footprint. * **Low EMI:** Ideal for high-density PCB layouts where components are packed closely together. * **Reliability:** Designed to handle high-temperature environments without significant inductance "roll-off."
