SIMPLE SWITCHER is a trademark of National Semiconductor Corp. 5. For SMT parts, optional Tape & Reel packaging can be ordered by addin a T suffix to the part number (i.e. PE-53801SNL becomes PE-53801SNLT). Pulse complies to industry standard tape and reel specification EIA481. 6. The NL suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necesssarily RoHS-compliant, but are electrically and mechanically equivalent to NL versions. If a part number does not have the NL suffix, but an RoHS compliant version is required, please contact Pulse for availability. SPM2007 47 (08/20) Power.PulseElectronics.com 2
