NOTES:

1. The temperature of the component (ambient temperature plus temper-

ature rise) must be within the specified operating temperature range.

2.The maximum current rating is based upon temperature rise of the

component and represents the DC current which will cause a typical

temperature rise of 40°C with no airflow when both one turn windings

connected in parallel.

3. To calculate the value of the terminating resistor (Rt) use the following

formula: Rt (

Ω) = Vref * N / (Ipeak_primary)

4. The peak flux density of the device must remain below 2000 Gauss. To

calculate the peak flux density for uni-polar current use following formula:

* for bi-polar current applications divide Bpk as calculated above by 2.

5. Add “T” suffix to the part number for Tape & Reel packaging, (i.e. P8222T).
