The center frequency, fC, is measured at the minimum IL point with the resonator in the 50Ω test system. Unless noted otherwise, case temperature TC = +25°C ± 2°C. Frequency aging is the change in fC with time and is specified at +65°C or less. Aging may exceed the specification for prolonged temperatures above +65°C. Typically, aging is greatest the first year after m...
