The **SRP0510-R68K** is a high-current shielded power inductor manufactured by **Bourns**. It is designed for high-density power applications such as DC/DC converters, laptops, and distributed power systems. ### 1. Key Technical Specifications The alphanumeric code "R68K" provides the core electrical parameters: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Inductance** | 0.68 µH | The nominal inductance value. | | **Tolerance** | ±10% | Indicated by the suffix "K". | | **Current (Irms)** | ~7.0 A | The current that causes a 40°C temperature rise. | | **Current (Isat)** | ~11.0 A | The current that causes a 30% drop in inductance. | | **DC Resistance (DCR)** | ~15.5 mΩ (Max) | Resistance of the internal copper wire. | | **Operating Temp** | -40 to +125 °C | Includes self-heating temperature rise. | --- ### 2. Component Construction The SRP0510 series utilizes a specific build style to ensure performance in harsh environments: * **Carbonyl Iron Powder Core:** Provides a "soft" saturation characteristic, meaning the inductance doesn't drop off instantly when current spikes. * **Magnetic Shielding:** The molded construction minimizes electromagnetic interference (EMI), which is critical for components placed near sensitive CPUs or RF modules. * **Lead-Free/RoHS Compliant:** Safe for modern manufacturing standards. --- ### 3. Footprint and Dimensions The "0510" in the part number refers to the physical dimensions of the SMD (Surface Mount Device) package: | Dimension | Measurement (mm) | | :--- | :--- | | **Length (L)** | 5.60 ± 0.3 | | **Width (W)** | 5.20 ± 0.2 | | **Height (H)** | 1.00 ± 0.2 | --- ### 4. Typical Applications Because of its low profile (1.0 mm height) and high current capability, the SRP0510-R68K is commonly used in: * **Smartphones & Tablets:** Power management for processors. * **SSD Drives:** Filtering power rails in slim form factors. * **POL (Point of Load):** Converting 12V or 5V rails to lower voltages for digital ICs.
