NOTE:
1. The current rating (Irated) is based upon the temperature rise of the component and represents the rms current which will cause a typical temperature rise of 40C.
2. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
3. Optional Tape & Reel packaging can be ordered by adding a “T” sux to the part number (i.e. PA2741NL becomes PA2741NLT). Pulse complies to industry standard tape and reel specification EIA481.
4. Components identified by an asterisk have an inductance tolerance of +/- 35%. All other components are +30/-35%.

Please note that for PA2741NL and PA2742NL the part should be connected as follows:
Customer to connect pins (1,2) and (4,3) together on board to form a single winding (1,2-4,3).
Customer to connect pins (8,7) and (5,6) together on board to form a single winding (8,7-5,6)
All ratings (leakage and DCR) are with respect to the above winding configuration.
