Typ. Typ. Max. C. General Information: 1. CSMS0412D-xxx_, “CSMS0412D” = P/N, “xxx” = Inductance, “_” = Tolerance. 2. Tolerance “_”: M: ± 20%, N: ± 30% 3. Magnetically shielded 4. High saturation current 5. Storage temperature: -40ºC to +85ºC. 6. Operating temperature range: -25ºC to +125ºC (Including self-heating). 7. Inductance measured using the HP4285A and Chroma1320 & 3302. 8. DCR measured using Chroma 16502. 9. SRF measured using the HP4291B. 10. Saturation Current Idc1: The value of current causes a 30% Inductance reduction from initial value. ( at : 20 ºC ambient) 11. Temperature rise current Idc2: The value of current causes a 40ºC temperature rise. ( at : 20 ºC ambient) 12. Rated Current: Either Idc1 or Idc2 whichever is smaller. 13. MSL: Level 1. 14. Inductance and Current range: From 1.0 µH (2200mA) to 22.0 µH (620mA). D. Applications: 1. 2. 3. 4. 5. 6.
