The devices are fully compatible with CECC00802 to 280°C which allows them to be placed and reflowed with IC’s, thus reducing time and cost in production. Co-planarity of the lead positions is based upon IEC 191-6:1990. The devices are suitable for all applications where high volume production is envisaged. NTA0515M NTA1205M NTA1209M NTA1212M NTA1215M When operated with additional external load capacitance the rise time of the input voltage will determine the maximum external capacitance value for guaranteed start up. The slower the rise time of the input voltage the greater the maximum value of the additional external capacitance for reliable start up.
