The **SRP0510F-R68M** is a high-current, shielded power inductor manufactured by Bourns. It is part of the SRP series, which is designed to meet the high-density requirements of modern consumer electronics and industrial applications. --- ## 1. Technical Specifications The part number encodes the specific electrical characteristics of the component. | Parameter | Value | Description | | :--- | :--- | :--- | | **Inductance** | 0.68 µH | Rated at 100 kHz / 1 V | | **Tolerance** | ±20% | Indicated by the "M" suffix | | **DC Resistance (DCR)** | 11.4 mΩ (Max) | Internal resistance of the coil | | **Irms (Heating Current)** | 8.5 A | Current causing 40°C temperature rise | | **Isat (Saturation Current)** | 11.5 A | Current causing 30% drop in inductance | | **Operating Temp** | -55°C to +125°C | Includes self-heating | --- ## 2. Key Features and Construction The SRP0510F-R68M is built using advanced materials to optimize performance in small footprints. * **Shielded Construction:** The inductor is molded with a metal alloy powder. This provides magnetic shielding, which minimizes Electromagnetic Interference (EMI) with surrounding components. * **Low Profile:** The "0510" size indicates a footprint of approximately 5.0 x 5.0 mm with a low height (approx 1.0 mm), making it ideal for ultra-thin devices. * **High Saturation Current:** Unlike traditional ferrite inductors that saturate abruptly, the metal alloy powder core allows for a "soft" saturation characteristic. * **RoHS Compliant:** Lead-free and halogen-free construction. --- ## 3.
