Notes:
1. 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 top-
ology, 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” sux to the part
number (i.e. PH9184.011NL becomes PH9184.011NLT). Pulse complies to industry
standard tape and reel specification EIA481.
3. The “NL” sux indicates an RoHS-compliant part number.
4. The temperature of the component (ambient plus the temperature rise) must be
within the stated operating temperature range.
