NOTES:
BPK = 37.59 * VREF * (Duty_Cycle_Max) * 105 / ( N * Freq_kHz)
* for bi-polar current applications divide BPK (as calculated above) by 2.
5. Part numbers P8222 to P8229 are reverse polarity versions of P820X.
1.The temperature of the component (ambient temperature plus
temperature rise) must be within the specified operating temperature range.
2.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.
3.To calculate the value of the terminating resistor (Rt) use the following
formula: Rt (Ω) = Vref * N / (Ipeak_primary)
4. 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:
6. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to
the part number (i.e. P8202 becomes P8202T). Pulse complies to industry
standard tape and reel specification EIA481.
7. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed
parts are not necessarily RoHS compliant, but are electrically 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.
