Notes:
1. The maximum volt-µsec rating limits the peak flux density to 2200 Gauss
when used in a unipolar drive application. For bi-polar drive applications a
maximum volt-µsec of two times this rating is acceptable (ie: 2* (volt*µsec
rating) Volt*µsec = (voltage applied to the primary) * dutycycle / Frequecy = V
* alpha / Freq_Hz = V * µsec
2. Leakage inductance is measured at primary terminals with all secondaries
shorted.
3. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to
the part number (i.e. PL2973 becomes PL2973T). Pulse complies to industry
standard tape and reel specification EIA481.

4. The “NL” suffix indicates an RoHS-compliant part number. Non-NL suffixed
parts are not necessarily RoHS compliant, but are electrically and mechani-
cally equivalent to NL versions. If a part number does not have the “NL” suffix,
but an RoHS compliant version
is required, please contact Pulse for availability.
5. The temperature of the component (ambient plus temperature rise) must
be within the stated operating temperature range.
