Notes:
1. The temperature of the component (ambient plus temperature rise) must be within the
stated operating temperature range.
2. Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with the
bias voltage applied between primary and secondary windings.
3. Optional Tape & Reel packaging can be ordered by adding a “T” sux to the part
number (i.e. (PA3964.001NL becomes PA3964.001NLT). Pulse complies with industry
standard tape and reel specification EIA481. The tape and reel for this product has a
width (W=32mm), pitch (Po=24mm) and depth (Ko) is equal to 8.0 for PA3964.XXXNLT
and 14.5 for PA3965.XXXNLT. PA3964.XXXNLT has 300pcs per reel. PA3965.XXXNLT has
150pcs per reel.
