Notes:

1. Pins 1-4 (connect 2 & 3), Pins 8-5 (connect 6 & 7)

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%.

3. Optional Tape & Reel packing can be ordered by adding a “

T” suffix to the part

number (i.e. PH9385.011NL becomes PH9385.011NL

T). Pulse complies to industry

standard tape and reel specification EIA481.

4. The “NL” suffix indicates an RoHS-compliant part number.

5. The temperature of the component (ambient plus temperature rise) must be

within the stated operating temperature range.
