The 1812 LQ SMT Unshielded Power Inductor is designed for compact switching power supply systems requiring efficient energy storage, stable inductance performance, and cost-effective PCB integration. Its unshielded structure provides a balance between performance and economic efficiency in low-to-medium power electronic applications.
Optimized for DC-DC converters and switching regulator circuits, the inductor supports reliable ripple current smoothing and stable operation under high-frequency switching conditions.
The 1812 platform is suitable for space-constrained electronic designs where moderate current handling capability and efficient power conversion are required.
Customized inductance values, current ratings, and winding configurations are available based on application requirements.
