The **SRP3012CC-R15Y** is a high-current, shielded power inductor manufactured by **Bourns**. It is specifically designed for high-density power applications such as DC/DC converters and power supplies in consumer electronics. --- ### 1. Technical Specifications The part number follows a specific nomenclature that defines its physical and electrical characteristics. | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.15 µH | | **Tolerance** | ±30% | | **Inductance Code** | R15 (0.15) | | **Case Size** | 3012 (approx. 3.0 x 3.0 x 1.2 mm) | | **DC Resistance (DCR)** | 6.5 mΩ (Typ) / 7.8 mΩ (Max) | | **Irms (Heating Current)** | 9.0 Amperes | | **Isat (Saturation Current)** | 14.5 Amperes | | **Operating Temp** | -40 °C to +125 °C | --- ### 2. Key Features * **Carbonyl Powder Core:** The inductor uses a metal alloy powder core which provides high saturation current and low core loss at high frequencies. * **Magnetic Shielding:** The construction is "shielded," meaning it minimizes electromagnetic interference (EMI) with surrounding components. * **Low Profile:** With a height of only 1.2 mm, it is ideal for ultra-thin devices like smartphones, tablets, and SSDs. * **High Current Handling:** Despite its small footprint, it can handle a saturation current up to 14.5A, which is critical for modern high-speed processors. --- ### 3. Applications The SRP3012CC series is typically found in: 1. **Voltage Regulator Modules (VRMs):** For CPUs and GPUs in laptops. 2. **DC/DC Converters:** Distributed power systems and battery-powered devices. 3. **Telecom/Datacom:** Small-cell base stations and networking equipment. --- ### 4. Component Footprint (Approximate) The "3012" designation refers to the metric/imperial hybrid sizing used by Bourns: * **Length:** 3.0 mm (± 0.2) * **Width:** 3.0 mm (± 0.2) * **Height:** 1.2 mm (Max)
