The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necessarily 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. 6. Series connection (pins 2-4 connected) 7. The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range.
