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 component
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) = V
REF
* N / (Ipeak primary)
3.
The peak flux density of device must remain below 2000 Gauss.
To calculate the peak flux density for a uni-polar current, use the following
formula:
Bpk = 64.9 * V
REF
* (Duty Cycle Max) * 10
5
/ (N * Freq kHz)
*for bi-polar current applications divide Bpk (as calculated above) by 2.
4. Optional Tape & Reel packaging can be ordered by adding
a "T" suffix to the part number (i.e. PA0368.050NL becomes
PA0368.050NLT). Pulse complies to industry standard tape and
reel specification EIA481.
5. The "NL" suffix indicates an RoHS-compliant part number. Non-NL
suffixed parts are not necessarily RoHS compliant, but are electri-
cally and mechanically equivalent to NL versions. If a part number
does not have the "NL" suffix, but an RoHS compliant version is
required, please contact Pulse for availability.
6. The temperature of the component (ambient plus temperature rise)
must be within the stated operating temperature range.
