10 µH Shielded Drum Core, Wirewound Inductor 7.5 A 30mOhm Max Nonstandard # Engineering Specification ## Product Name SRP1038A-100M ## General Description SRP1038A-100M is a shielded surface mount power inductor designed for use in high-efficiency DC-DC conversion and power management applications. The device is intended to support energy storage and current smoothing functions in switching regulator circuits, where stable inductance performance and low power loss are critical. The inductor utilizes a ferrite core construction with a shielded magnetic structure to minimize electromagnetic interference and reduce magnetic flux leakage. This enables improved circuit density and reduced noise coupling in compact electronic assemblies. The design is optimized for use in high current power conversion systems, including buck converters, point-of-load regulators, and distributed power architectures. The component is widely used in industrial, automotive, telecommunications, and embedded systems where reliable energy transfer, thermal stability, and efficient power delivery are required. Its surface mount form factor supports automated PCB assembly and compact system integration while maintaining mechanical robustness under thermal and electrical stress. The design emphasizes low direct current resistance, high current handling capability, and stable inductance behavior under load conditions. It is suitable for applications requiring efficient power conversion with minimal energy loss and stable electromagnetic performance. ## Functional Requirements ### Energy Storage The device shall store energy in a magnetic field during switching operation in power conversion circuits. ### Current Filtering The device shall smooth current ripple in switching regulator applications to maintain stable output conditions. ### Electromagnetic Shielding The device shall reduce electromagnetic interference through a shielded magnetic structure. ### Power Conversion Support The component shall support efficient operation in DC-DC conversion systems. ## Electrical Requirements ### Inductive Performance The device shall provide stable inductance characteristics suitable for power conversion and filtering applications. ### Low Loss Operation The inductor shall minimize resistive and core losses to improve overall system efficiency. ### High Current Capability The device shall support operation under elevated current conditions typical of switching power supplies. ### Thermal Stability The inductor shall maintain performance consistency under thermal loading and temperature variation. ## Mechanical Requirements ### Surface Mount Package The device shall be supplied in a surface mount configuration suitable for automated PCB assembly processes. ### Structural Integrity The component shall withstand mechanical stress during assembly, operation, and thermal cycling. ### PCB Integration The design shall support compact layout integration in multilayer printed circuit board systems. ## Environmental Requirements ### Operating Conditions The device shall operate reliably under conditions typical of industrial and embedded electronic systems. ### Thermal Performance The component shall maintain stable operation under continuous power cycling and heat generation. ### Storage and Handling The device shall retain structural and electrical integrity during storage, transportation, and handling. ## Quality Requirements ### Reliability The inductor shall provide consistent long-term performance under continuous electrical and thermal stress. ### Verification Electrical and thermal characteristics shall be validated through appropriate qualification and testing procedures. ### Compliance The product shall conform to applicable standards for magnetic components used in power electronics applications. ## Documentation Requirements Technical documentation shall include application guidance, layout recommendations for switching power designs, thermal considerations, electrical characteristics, and integration practices for DC-DC converter systems. ## Classification Tags #SRP1038A100M #PowerInductor #ShieldedInductor #SMDInductor #MagneticComponent #EnergyStorageInductor #DCDCConverter #BuckConverter #PowerElectronics #SMPSDesign #ElectromagneticCompatibility #EMIShielding #PCBDesign #ElectricalEngineering #EmbeddedPower #IndustrialElectronics #AutomotiveElectronics #CommonPartsLibrary #ComponentLibrary #EngineeringSpecification #PowerManagement #CircuitDesign #HighCurrentInductor
