2.2µH 1.7A High-SRF SMD Power Chip Inductor | SPS1812 Series
The 2.2µH 1.7A High-SRF SMD Power Chip Inductor | SPS1812 Series delivers a robust, 100% compatible solution for engineers and procurement professionals seeking an alternative to Coilcraft’s 1812FS line. Featuring a high self-resonant frequency (SRF), low DC resistance (DCR), and superior current handling, these shielded power inductors excel in DC-DC converters, RF circuits, and EMI filtering applications. Their magnetically shielded design minimizes electromagnetic interference, ensuring reliable performance in automotive, industrial, and consumer electronics environments. Despite their strength, these inductors stand at a compact 4.2 mm in height, making them perfect for space-constrained layouts.
Engineered to meet modern demands for power management, signal integrity, and noise suppression, the SPS1812 Series strikes a perfect balance between cost-effectiveness and high performance. These inductors support quick lead times and straightforward compatibility for a wide range of designs. Contact us today to request a quote or learn more about how the SPS1812 Series can elevate your next project.
Customization
The SPS1812 Series not only serves as a 100% alternative to Coilcraft 1812FS inductors but also offers tailored options to meet unique design requirements. Whether you need adjusted inductance values, specialized current handling, or stricter tolerance thresholds, we can customize the electrical characteristics to seamlessly fit your application. This flexibility ensures you achieve optimal efficiency, reliability, and noise suppression in automotive, industrial, or consumer electronics environments—all while benefiting from quick lead times and cost-effective solutions.
Leadtime
Coilmaster’s standard lead time is 6~8 weeks, in urgent case, the fast delivery program is available. For specific product series, we could send out the goods within 10 or 20 working days.
