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 (W) = 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
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. PA1005.020NL becomes PA1005.020NLT). Pulse
complies to industry standard tape and reel specification EIA481.
6. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suf-
fixed parts are not necessarily RoHS compliant, but are electrically and
mechanically equivalent to NL versions. If a part number does not have
the “NL” suffix, but an RoHS compliant version is required, please con-
tact Pulse for availability.
