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.
