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-sec of two times this rating is acceptable (ie: 2* (volt*µsec rating) = (voltage

applied to the primary) * dutycycle / Frequency = 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. P0544NL becomes P0544NLT). 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 mechanically 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.
