1. Unless noted otherwise, case temperature TC = +25°C±2°C.

2. The center frequency, fC, is measured at the minimum insertion loss point with the resonator in the 50Ω test system.

3. 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 manufacture, decreasing in

subsequent years.

4. Turnover temperature, TO, is the temperature of maximum (or turnover) frequency, fO. The nominal frequency at any

case temperature, TC, may be calculated from: f = fO [1 - FTC (TO - TC)2].

5. This equivalent RLC model approximates resonator performance near the resonant frequency and is provided for

reference only. The capacitance CO is the static capacitance between the two terminals measured at low frequency

(10MHz) with a capacitance meter. The measurement includes case parasitic capacitance.
