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.
2. Optional Tape & Reel packing can be ordered by adding a “T” suffix to the part number
(i.e. PH9185.012NL becomes PH9185.012NLT). Pulse complies to industry standard tape
and reel specification EIA481.
3. The “NL” suffix 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.
