Land Pattern
C. Feature:
1. Tolerance: M: ± 20%, L: ± 15%, K: ± 10%.
2. Operating temperature: -25ºC TO +85ºC.
3. Electrical specifications at +25ºC.
4. Inductance measured on the HP4284A LCR meter.
5. DCR measured on the 502BC milli-ohm meter.
6. Inductance drops no more than 10% at rated I sat.
7. Temperature rises ∆ t < 15ºC (Typical) at rated I rms.
8. Enclosed in a flat top ceramic case.
Note: RoHS compliant; for the ROHS parts, we add “-LFR” at the end of the P/N.
