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) = V
REF
* 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:
B
PK
= 14.29 * V
REF
* (Duty_Cycle_Max) * 10
5
/ ( N * Freq_kHz)
* for bi-polar current applications divide B
PK
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-68210 becomes PE-68210T). Pulse complies to
industry standard tape and reel specification EIA481.
6. RoHS compliant parts are being introduced. Please contact Pulse for RoHS
compliant part availability. If available, order part by adding “NL” to the part
number (i.e. PE-68210 becomes PE-68210NL and PE-68210T becomes
PE-68210NLT).
