B. General Information:
Type 2
1. P/N: 1812SDF-xxx_: “1812SDF” = Type, “xxx” = Inductance, “_” = Tolerance.
2. Tolerance “_” : J = ± 5%, K = ± 10%, M = ± 20%.
3. Operating temperature: -25ºC to +85ºC.
4. Electrical specifications at +25ºC.
5. Inductance measured on the HP4284A LCR meter
6. DCR measured on the 502BC milli-ohm meter.
7. I DC: Inductance drops no more than 10% at rated current or the ∆t ≤ 40ºC.
8. Temperature rise Δ t < 40ºC (Typical) at rated current and room temperature 20ºC.
9. Inductance and Current Range: From 1.0 uH (1080 mA) to 470 uH (90 mA)
10. SRF: From 3.0 MHz to 100 MHz
11. Tape and reel packing.
12. Suitable for IR re-flows soldering.
13. MSL: Level 1.
C. Applications:
1. Power supply line chokes.
2. DC-DC Converters.
3. Notebooks.
4. Filters.
5. Telecommunication devices.
