The **SRP7030-R72M** is a high-current, shielded power inductor manufactured by **Bourns**. It is designed for high-density power supply applications, particularly in DC/DC converters. ### Technical Specifications The following table summarizes the primary electrical and physical characteristics: | Parameter | Value | | :--- | :--- | | **Inductance** | 0.72 µH | | **Tolerance** | ±20% | | **Current Rating (Irms)** | 14.5 A | | **Saturation Current (Isat)** | 21.0 A | | **DC Resistance (DCR)** | 5.2 mΩ (Max) | | **Operating Temperature** | -40 °C to +125 °C | | **Package / Case** | 7.3 mm x 6.6 mm x 3.0 mm (SMD) | | **Construction** | Metal Alloy Powder Core (Shielded) | --- ### Core Features and Functions #### 1. Magnetic Shielding The inductor features a **shielded construction**. This means the magnetic flux is contained within the component body. * **Benefit:** It minimizes Electromagnetic Interference (EMI) with surrounding components on the PCB, which is critical in compact electronic designs. #### 2. Metal Alloy Powder Core Unlike traditional ferrite cores that saturate abruptly, the SRP series uses a **metal powder core**. * **Soft Saturation:** When the current exceeds the rated limit, the inductance drops gradually rather than crashing. This provides a safety margin in high-load scenarios. #### 3. High Current Handling With an **Isat of 21 Amps**, this part is capable of handling significant power surges without losing its inductive properties. The low DC resistance (DCR) ensures that energy loss through heat is kept to a minimum. --- ### Typical Applications * **DC/DC Converters:** Used as a storage element in buck, boost, and buck-boost regulators. * **Computing:** Powering CPUs, GPUs, and high-speed memory in servers or laptops. * **Industrial Electronics:** Distributed power systems and battery-powered devices. * **Automotive:** (If qualified) Infotainment and driver assistance systems. ### Part Number Breakdown * **SRP:** Series prefix (High current power inductors). * **7030:** Dimensions (~7.0mm x 3.0mm height). * **R72:** Inductance value (R72 = 0.72 µH). * **M:** Tolerance (M = ±20%).
