P/N: 1812SDF-xxx_: “1812SDF” = Type, “xxx” = Inductance, “_” = Tolerance.
Tolerance “_” : J = ± 5%, K = ± 10%, M = ± 20%.
Operating temperature: -25ºC to +85ºC.
Electrical specifications at +25ºC.
Inductance measured on the HP4284A LCR meter
DCR measured on the 502BC milli-ohm meter.
I DC: Inductance drops no more than 10% at rated current or the ∆t ≤ 40ºC.
Temperature rise Δ t < 40ºC (Typical) at rated current and room temperature 20ºC.
Inductance and Current Range: From 1.0 uH (1080 mA) to 470 uH (90 mA)
SRF: From 3.0 MHz to 100 MHz
Tape and reel packing.
Suitable for IR re-flows soldering.
MSL: Level 1.
