Pletronics may ship the following combinations without notice (this is an enhanced specified device)
44 (25 ppm) stability parts when 45 (50 ppm) was ordered
20 (20 ppm) stability parts when 45 (50 ppm) or 44 (25 ppm) was ordered.
E temperature range parts when extended was not ordered.
S symmetry parts when 40/60% symmetry was ordered.
Pletronics may ship parts that are not marked for extended temperature range but were tested for
extended temperature range, a Certificate of Conformance will accompany these parts.
