Inductance: 1MHz, 0.1Vrms, 0Adc test condition, Ta=25℃.
DCR: DC micro-ohmmeter measurement.
SRF: High-precision network analyzer test.
Isat: DC current at which inductance drops by specified percentage at 25℃; derating required for high-temperature applications.
Irms: DC current causing specified temperature rise (20℃/40℃); for reference only, actual verification required in end-system testing.
Terminal Code: SN=Sn-Ni, SAC=Sn-Ag-Cu; SP=Sn-Pb (non-RoHS).
Packaging: Tape & reel, complies with EIA-481 standards; supports 7-inch / 13-inch reels.
Electrical Test Conditions: Ta=25℃, specifications subject to change without notice.

Features

· Lowest DC resistance with significantly reduced AC losses, outstanding performance at high frequencies

· Higher inductance in the same PCB footprint; smaller footprint for the same inductance, ideal for high-density layouts

· Substantially enhanced Irms (temp rise current) and Isat (saturation current), resulting in lower heat generation and higher efficiency

Applications

· Servers, PC motherboard VRM/VRD, CPU core power delivery (Core Application)

· High-density high-current power modules, high-performance FPGA/SoC power stages

· Industrial high-power systems requiring high efficiency and low temperature rise

· Automotive electronics and telecom equipment with strict dimensional constraints
