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.
