The **SRP1206-R60Y** is a high-current, shielded power inductor manufactured by **Bourns**. It is designed for high-density power applications where reliability and low electromagnetic interference (EMI) are critical. ### 1. Key Technical Specifications The model number encodes the physical size and the electrical characteristics of the component. | Parameter | Specification | | :--- | :--- | | **Inductance** | 0.60 µH (Microhenries) | | **Tolerance** | ±20% | | **Current Rating (Irms)** | ~28.0 Amperes (Typical) | | **Saturation Current (Isat)** | ~40.0 Amperes (Typical) | | **DC Resistance (DCR)** | ~1.5 mΩ (Maximum) | | **Operating Temperature** | -40 °C to +150 °C | | **Core Material** | Carbonyl Powder (Iron Powder) | --- ### 2. Physical Dimensions (1206 Series) The "1206" in the part number refers to the physical footprint size (approximately 13.5mm x 12.5mm), not to be confused with 1206 SMD resistor sizes. * **Length:** 13.5 mm (max) * **Width:** 12.5 mm (max) * **Height:** 6.0 mm (max) --- ### 3. Core Features & Construction * **Magnetic Shielding:** The inductor is molded around the coil using a metallic powder. This construction provides excellent EMI shielding, preventing the magnetic field from interfering with nearby sensitive circuits. * **High Saturation:** Unlike ferrite inductors that drop inductance sharply when current increases, the SRP series has a "soft" saturation curve due to the iron powder core. * **AEC-Q200 Compliance:** This specific series is often used in automotive applications because it is ruggedized against vibration and high heat. --- ### 4. Common Applications This component is typically found in high-efficiency DC-DC converters and power management systems: 1. **Voltage Regulator Modules (VRMs):** Found on high-performance PC motherboards and servers. 2. **Automotive Electronics:** Driver assistance systems, infotainment, and lighting power modules. 3. **Industrial Power Supplies:** Used in distributed power systems and DC-DC converters for heavy machinery controls. 4. **Consumer Electronics:** High-current power stages for large displays or gaming consoles. --- ### 5.
