Typ. Typ. Tol. Max. C. General Information: 1. CSMH0312D-xxx_, “CSMH0312D” = P/N, “xxx” = Inductance, “_” = Tolerance. 2. Tolerance “_”: N = ± 30%, M = ± 20%. 3. Operating temperature range: -25ºC to +120ºC (Including self-heating). 4. Storage temperature: -40ºC to +85ºC. 5. Inductance measured using the HP4285A and Chroma1320 & 3302. 6. DCR measured using Chroma 16502. 7. SRF measured using the HP4291B. 8. Saturation Current Idc1: The value of current causes a 30% Inductance reduction from initial value. ( at : 20 ºC ambient) 9. Temperature rise current Idc2: The value of current causes a 40ºC temperature rise. ( at : 20 ºC ambient) 10. Rated Current: Either Idc1 or Idc2 whichever is smaller. 11. MSL: Level 1. 12. Inductance and Current range: From 1.0 µH (1.710 A) to 22.0µH (0.5 A). D. Applications: 1. 2. 3. 4. 5. 6.
