Temperature sensitive crystals

General application
High precision temperature measurement (sensitivity mK)

High sensitivity, good / excellent linearity, high long-term stability

Temperature sensitive crystals can by assembled in metal packages designed for through hole mount (i.e. HC-49HC-52, UM-1, UM-4, UM-5), as well as in ceramic packages [a]

Typical specifications
Type Temperature crystals
 Frequency range 4 - 40 MHz
 Sensitivity of frequency on temperature 20 - 90 ppm/K
 Working temperature range -50 ... +125 (+200 [b]) °C
 Non-linearity 5 x 10-2 ... 1 x 10-3 [c]
 Equivalent series resistance (ESRmax) 5 ... 50 ohm [d]
 Time constant for temperature step 10°C [e] for sensitivity 0,1°C
for sensitivity 0,01°C
for sensitivity 0,001°C
101 sec
1 min
3 ... 10 min

[a] - ceramic packages have a longer time constant
[b] - temp. range can be extended up to +200°C at the expense of slightly worsened hysteresis and aging
[c] - nonlinearity closely related to sensitivity
[d] - ESRmax depends on the choice of frequency and package size
[e] - The time constant depends on the type of package, gas filling of package, environmental conditions, etc.

Differences from standard values and other parameters can be consulted.
