C. Features:

1. Tolerance: M: ± 20%.

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. Temperature rises

∆ t < 15ºC (Typical) at rated I rms.

7. Average maximum allowable current: CST042C series are designed for current spikes as high as 2 times the current rated.

8. Inductance range: CST 042C series from 1.0uH(2.00A) to 1000uH(0.08A).
