The **SRP5030TA-R68M** is a high-current, shielded power inductor manufactured by Bourns. It is commonly used in DC/DC converters and power supplies for automotive and industrial electronics. --- ## 1. Technical Specifications The part number itself encodes the core specifications of the component. | Parameter | Value | Description | | :--- | :--- | :--- | | **Inductance** | 0.68 µH | The nominal inductance value. | | **Tolerance** | ±20% (M) | The allowable variance from nominal inductance. | | **Inductance Code** | R68 | Decimal notation for 0.68. | | **Current Rating (Irms)** | 14 A | Current that causes a 40°C temperature rise. | | **Saturation Current (Isat)** | 25 A | Current where inductance drops by 30%. | | **DC Resistance (DCR)** | 4.5 mΩ (Typ) | Internal resistance of the coil. | | **Operating Temp** | -40 to +150 °C | High-grade thermal range. | --- ## 2. Key Features * **Shielded Construction:** The inductor is magnetically shielded, which minimizes electromagnetic interference (EMI) with surrounding components. * **Metal Alloy Powder Core:** Unlike traditional ferrite cores, the metal powder core provides a "soft" saturation characteristic, preventing a sudden drop in inductance during current spikes. * **AEC-Q200 Compliant:** The "TA" suffix often denotes automotive-grade testing, making it suitable for harsh environments and vibration-prone applications. * **Low DCR:** The extremely low resistance ensures high efficiency and minimal heat dissipation. --- ## 3. Physical Dimensions The "5030" in the part number refers to the physical footprint of the Surface Mount Device (SMD). | Dimension | Measurement (mm) | | :--- | :--- | | **Length** | 5.70 ± 0.3 | | **Width** | 5.20 ± 0.2 | | **Height** | 2.80 ± 0.2 | --- ## 4. Typical Applications 1. **Automotive Systems:** Driver assistance (ADAS), infotainment, and lighting. 2. **Voltage Regulator Modules (VRM):** Used in high-speed computing power supplies. 3. **DC/DC Converters:** Point-of-load (POL) converters for industrial equipment. ---
