The SPM6530T-2R2M from TDK is a 2.2uH shielded SMD power inductor rated at 30A saturation current in a 6.5×6.5mm package for DC-DC converter output filters.
The SPM6530T-2R2M is a 2.2uH shielded power inductor from TDK in a 6.5×6.5×3.0mm SMD package. It uses a metal composite core (soft magnetic powder compacted around the winding), which provides high saturation current and low core losses at switching frequencies from 100kHz to 5MHz. The shielded construction means the magnetic flux is largely contained within the core, minimizing EMI radiation and preventing coupling to nearby traces or components. Key specifications: saturation current Isat = 30A (at which inductance drops 30% from nominal), rated current Irms = 10.5A (at which temperature rise is 40C above ambient), DC resistance DCR = 2.8mOhm typical. The distinction between Isat and Irms is critical: Isat defines the magnetic limit (core saturation), while Irms defines the thermal limit (copper heating). In a buck converter, the peak inductor current must stay below Isat, and the RMS current below Irms. The 2.2uH inductance at 500kHz switching frequency with 12V input and 3.3V output results in approximately 3.2A peak-to-peak ripple current at 10A load. The metal composite core has lower core loss than ferrite at high frequencies (above 1MHz), making it suitable for modern high-frequency DC-DC converters. The SPM6530 series footprint is compatible with other 6.5×6.5mm inductors. The -2R2M suffix specifies 2.2uH, +/-20% tolerance.
