Height: 3.3mm Max
Footprint: 8.4mm x 8.4mm Max
Current Rating: up to 4A
Frequency Range: 50kHz to 1MHz
NOTES:
1. The maximum current rating is based on temperature rise of the compo-
nent and represents the dc current which will cause a typical temperature
rise of 40°C with no airflow.
2. To calculate the value of the terminating resistor (Rt) use the following
formula: Rt (Ω) = Vref * N / (Ipeak primary)
3. The peak flux density of the device must remain below 2000 Gauss. To calculate
the peak flux density for a uni-polar current, use the following formula:
Bpk = 64.9 * Vref * (Duty Cycle Max) * 10 5/ (N * Freq kHz)
*for bi-polar current applications divide Bpk as calculated above by 2).
4. Add “T” suffix to the part number for Tape & Reel packaging, (i.e. PA0368.050T)
