Notes:
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 40C with no airflow.
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:
BPK = 37.59 * VREF * (Duty_Cycle_Max) * 10 / (N * Freq_kHz)
* for bi-polar current applications divide BPK (as calculated above) by 2.
5. Part number P8222 to P8229 are reverse polarity versions of P820X.
6. Optional Tape & Reel packaging can be ordered by adding a “T” sux to the part
number (i.e. P8202NL becomes P8202NLT). Pulse complies to industry standard
tape and reel specification EIA481.
7. 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.
