NOTES:
1. The temperature of 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 airflow when both one turn windings
connected in parallel.
3. To calculate value of 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 uni-polar current use following formula:
Bpk = 37.59 * V
REF
* (Duty_Cycle_Max) * 10
5
/ (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. PA1005.020 becomes PA1005.020T). Pulse
complies to industry standard tape and reel specification EIA481.
6. To order RoHS compliant part, add the suffix "NL" to the part number
(i.e. PA1005.020 becomes PA1005.020NL and PA1005.020T becomes
PA1005.020NLT). Please note that the PA1005.125 part is not available
in an RoHS compliant version.
