## VP2-0066-R Electronic Component Overview The **VP2-0066-R** is a high-performance, surface-mount power inductor (often referred to as a Versa-Pac™ transformer/inductor) manufactured by **Eaton (formerly Bussmann/Coiltronics)**. This specific part is known for its versatility, featuring multiple windings that allow it to be configured in various ways for power conversion circuits. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Manufacturer** | Eaton (Coiltronics) | | **Series** | Versa-Pac™ (VP Series) | | **Inductance (Parallel)** | ~6.7 µH (approximate, varies by config) | | **Inductance (Series)** | ~240 µH (approximate, varies by config) | | **Current Rating (Isat)** | ~1.4 A to 9.2 A (Configuration dependent) | | **Number of Windings** | 6 independent windings | | **DC Resistance (DCR)** | ~22 mΩ per winding | | **Mounting Type** | Surface Mount (SMD) | | **Operating Temp** | -40°C to +125°C | --- ### 2. Physical Structure and Design The VP2-0066-R is built using a **toroidal ferrite core** housed in a low-profile, surface-mount package. * **Multi-Winding Construction:** It contains six identical windings. This is the "Versa" in Versa-Pac, as the user can connect these windings in series or parallel to change the inductance and current handling. * **High Power Density:** Because it uses a toroid design, it has low electromagnetic interference (EMI) and high efficiency in a small footprint. * **RoHS Compliant:** The "-R" suffix indicates that the part is lead-free and meets RoHS standards. --- ### 3. Common Applications Due to its configurable nature, the VP2-0066-R is used in several power electronic roles: * **DC-DC Converters:** Buck, Boost, Forward, and Flyback converters. * **Voltage Isolation:** Can be used as a 1:1 or step-up/step-down transformer. * **Filtering:** Used as a common-mode choke or high-current inductor for ripple suppression. * **Battery Powered Systems:** Ideal for portable electronics where space and efficiency are critical. --- ### 4. Configuration Logic The primary advantage of the VP2-0066-R is the flexibility of its six windings. Users can map the pins to achieve different results: 1. **Parallel Connection:** Increases the current-carrying capacity (Amps) while keeping inductance low. 2. **Series Connection:** Increases the total inductance (Henries) but reduces the maximum current rating. 3. **Tapped/Transformer Connection:** Windings can be split between primary and secondary sides to create isolated outputs. ---
