For SMT parts, optional Tape & Reel packaging can be ordered by addin a "T" suffix to the part number( i.e. P0841SNL becomes P0841SNLT). Pulse complies to industry standard tape and reel specification EIA481. 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. Series connection (pins 2-4 connected) 1 power.pulseelectronics.com 7. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
