Description
Features
Q-Tech’s surface-mount QT89 oscillators consist of an IC
5Vdc, 3.3Vdc, 2.5Vdc, 1.8Vdc clock square wave
generator and a round AT high-precision quartz crystal
built in a rugged leaded miniature package. This package
is primarily designed for down-hole applications with
5Vdc or 3.3Vdc supply voltage.

1.8 to 5.0Vdc - 15kHz to 160MHz
Unless otherwise specified, soldering should be performed on terminals at 260ºC for 10s maximum. Do not apply soldering heat on
oscillator package since it could damage the unit. Hand soldering is recommended. Wave solder at 245ºC for 15s max.
The heat transfer model in a hybrid package is described in
figure 1.
Heat spreading occurs when heat flows into a material layer of
increased cross-sectional area. It is adequate to assume that
spreading occurs at a 45° angle.
The total thermal resistance is calculated by summing the
thermal resistances of each material in the thermal path be-
tween the device and hybrid case.

• Theta junction to case (Theta JC) for this product is 30°C/W.
• Theta case to ambient (Theta CA) for this part is 100°C/W.
• Theta Junction to ambient (Theta JA) is 130°C/W.
Maximum power dissipation PD for this package at 25°C is:
• PD(max) = (TJ (max) – TA)/Theta JA
• With TJ = 175°C (Maximum junction temperature of die)
• PD(max) = (175 – 25)/130 = 1.15W
