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 3. The “NL” suffix indicates an RoHS-compliant part number.
and reel specification EIA481.
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
4. The temperature of the component (ambient plus the temperature rise) must be
within the stated operating temperature range.
