Basic Insulation (1.4mm creepage and clearance between Primary and Secondary)

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.

5. The temperature of the component (ambient plus temperature rise) must be within the

stated operating temperature range.

6. Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with the bias

voltage applied between primary and secondary windings
