Pulse complies to industry standard tape and reel specification EIA481.
6. RoHS compliant parts are being introduced. Please contact Pulse for
RoHS compliant part availability. If available, order part by adding the
suffix “NL” to the part number (i.e.PE-53801 becomes PE-53801NL and
PE-53801T becomes PE-53801NLT).
7. The temperature of the component (ambient plus temperature rise) must
be within the stated operating temperature range.
