The maximum volt-usec rating limits the peak flux density to 3600 gauss when used in bi-polar drive application with 200KHz. For unipolar drive applications or a bi-polar drive with 350kHz, a maximum volt-usec could be 60% of the listed value. For Push-Pull topology, where the voltage is applied across half the primary winding turns, the maximum volts-use needs to be derated by 50%. 2. Optional Tape & Reel packing can be ordered by adding a “ **T** ” suffix to the part number (i.e. PH9084.011NL becomes PH9084.011NL **T** ). Pulse complies to industry standard tape and reel specification EIA481. 3. The “NL” suffix indicates an RoHS-compliant part number. **==> picture [78 x 25] intentionally omitted <==** **----- Start of picture text -----**
