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.
