The **UP2C-150-R** is a high-performance, shielded power inductor designed by **Eaton (formerly Bussmann)**. It belongs to the Uni-Pac (UP) series, which is specifically engineered for high power density and surface-mount (SMD) applications. --- ## 1. Key Specifications The following table highlights the primary electrical and physical characteristics of the UP2C-150-R: | Parameter | Specification | | :--- | :--- | | **Inductance** | 15.0 µH | | **Tolerance** | ±20% | | **Current Rating (Irms)** | 2.5 Amps | | **Saturation Current (Isat)** | 2.6 Amps | | **DC Resistance (DCR)** | 0.0541 Ω (54.1 mΩ) Max | | **Operating Temperature** | -40°C to +125°C | | **Shielding** | Magnetic Shielded | | **Mounting Type** | Surface Mount (SMD) | --- ## 2. Technical Features ### Magnetic Shielding The "2C" designation refers to the specific core shape and shielding. The inductor is encased in a ferrite material that minimizes **Electromagnetic Interference (EMI)**. This is crucial for dense PCB layouts where magnetic fields could disrupt neighboring sensitive components. ### Core Material It utilizes a ferrite core characterized by low core losses. This makes the component highly efficient in high-frequency switching environments, reducing heat generation. ### Construction * **Uni-Pac Design:** The UP series features a rugged construction with a flat top, making it ideal for high-speed automated "pick and place" assembly. * **Reliability:** The materials used are compliant with lead-free soldering processes and are RoHS compliant. --- ## 3. Common Applications Due to its balance of inductance and current handling, the UP2C-150-R is typically found in: * **DC-DC Converters:** Used as an energy storage element in buck, boost, and forward converters. * **Power Supplies:** Common in laptop adapters, servers, and industrial power modules. * **Consumer Electronics:** Integrated into LED drivers, battery chargers, and gaming consoles. * **Noise Filtering:** Acting as a low-pass filter to smooth out ripples in power lines. --- ## 4.
