The frequency fc is the frequency of minimum IL with the resonator in the specified test fixture in a 50Ω test system with VSWR ≤ 1.

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 manufacture, decreasing in subsequent years.
Turnover temperature, T0, is the temperature of maximum (or turnover) frequency, f0.
The nominal frequency at any case temperature, TC, may be calculated from: f = fo [1 - FTC (TO - TC)2].
This equivalent RLC model approximates resonator performance The measurement includes case parasitic capacitance.
