## **Notes:** 

1. The maximum volt-µsec limits the peak flux density to 2800 Gauss when used in a unipolar drive application. For bi-polar drive applications, a maximum volt-µsec of two times this rating is acceptable (i.e. 2* (volt*µsec rating) Volt*µsec = (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. PA2002NL becomes PA2002NL **T** ). 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.
