1. 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.
2. To calculate value of terminating resistor (Rt) use the following formula:
Rt (W) = Vref * N /(Ipeak_primary)
3. 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:
Bpk = 64.9 * Vref * (Duty_Cycle_Max) * 105 / (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” sux to the part num-
ber (i.e. PA0368.050NL becomes PA0368.050NLT). Pulse complies to industry standard
tape and reel specification EIA481.
5. The “NL” sux indicates an RoHS-compliant part number. Non-NL suxed parts are
not necessarily RoHS compliant, but are electrically and mechanically equivalent to NL
versions. If a part number does not have the “NL” sux, 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 ranger.
