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) = 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 .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 .
