Optional Tape & Reel packaging can be ordered by adding a "T" suffix to the part number (i.e. P0502 becomes P0502T). Pulse complies to industry standard tape and reel specification EIA481. 2. To order RoHS compliant part, add the suffix “NL” to the part number (i.e. P0502 becomes P0502NL and P0502T becomes P0502NLT). 3. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
