NOTES:

The temperature of component (ambient temperature plus temper-ature rise) must be within the

specified operating temperature range.

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.

Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e.

PA1005.020QNL becomes PA1005.020QNLT). Pulse complies to industry standard tape and reel

specification EIA481.

The “NL” suffix indicates an RoHS-compliant part number.

To calculate value of terminating resistor (Rt) use the following formula:

Rt (W) = Vref * N / (Ipeak_primary)

The peak flux density of the device must remain below 2000 Gauss. To calculate the peak flux den-

sity for uni-polar current use following formula:

Bpk = 37.59 * Vref * (Duty_Cycle_Max) * 10⁵/ (N * Freq_kHz)

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