RFMD Green: RoHS status based on EU
Directive 2011/65/EU (at time of this
document revision), halogen free per IEC
61249-2-21, < 1000ppm each of
antimony trioxide in polymeric materials
and red phosphorus as a flame retardant,
and <2% antimony in solder.
Exceeding any one or a combination of the Absolute
Maximum Rating conditions may cause permanent
damage to the device. Extended application of Absolute
Maximum Rating conditions to the device may reduce
device reliability. Specified typical performance or
functional operation of the device under Absolute
Maximum Rating conditions is not implied.
