NOTES:
1. The temperature of the component (ambient temperature plus 5
Bkp = 37.59 * Vref * (Duty_Cycle_Max) * 10 / ( N * Freq_kHz)
temperature rise) must be within the specified operating temperature range.
* for bi-polar current applications divide Bpk (as calculated above) by 2.
2.The maximum current rating is based upon temperature rise of the
component and represents the DC current which will cause a typical
5. Part numbers P8222 to P8229 are reverse polarity versions of P820X.
temperature rise of 40C with no airflow when both one turn windings
connected in parallel.
6. Optional Tape & Reel packaging can be ordered by adding a T suffix to
the part number (i.e. P8202NL becomes P8202NLT). Pulse complies to
3. To calculate the value of the terminating resistor (Rt) use the following
industry standard tape and reel specification EIA481.
formula: Rt (W) = Vref * N / (Ipeak_primary)
7. The NL suffix indicates an RoHS-compliant part number. Non-NL suffixed
4. The peak flux density of the device must remain below 2000 Gauss. To
parts are not necessarily RoHS compliant, but are electrically and mechanically
calculate the peak flux density for uni-polar current use following formula:
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.
