NOTES:

4.
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.
To calculate value of terminating resistor (Rt) use the following formula:
Rt (W) = V
ref
* 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 * V
ref
* (Duty_Cycle_Max) * 10
5
/ (N * Freq_kHz)
* for bi-polar current applications divide Bpk (as calculated above) by 2.

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.
