NOTES:
1.The temperature of the component (ambient temperature plus temper-
ature 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 air flow 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 a uni-polar current use the
following formula:
BPK = 14.29 * VREF * (Duty_Cycle_Max) * 105/ ( N * Freq_kHz)
* for bi-polar current applications divide BPK as calculated above by 2.
5. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to
the part number (i.e. PE-68210NL becomes PE-68210NLT). Pulse complies
to industry standard tape and reel specification EIA481.
6. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed
parts are not necessarily RoHS compliant, but are electrically and mechani-
cally 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.
