Precision Crystals have low-profile, surface mount enclosure.

Press Release Summary:

Assembled in vacuum for maximized Q values and phase noise, SMP-8 (8–130 MHz) and SMX (6–220 MHz) measure 8.0 x 7.2 x 2.3 mm, utilize braze seal, and can be made with custom specifications for precision SC cut, AT cut, and IT cut crystals. Heat transfer properties of 4-point mount make these products suited for OCXO designs. Additionally, thermal transfer properties and Q of SMX-8 can improve thermal perturbation levels. Options include high-temperature versions and internal thermistor.

Original Press Release:

Precision Low Profile Crystals from LapTech

Laptech’s SMP-8 (8-130)MHz and SMX(6-220)MHz have a low profile SMD enclosure (8.0 x 7.2 x 2.3) mm and can be made with custom specifications for precision SC cut, AT cut and IT cut crystals. They utilizes a braze seal and are assembled in a vacuum resulting in higher Q values and therefore improved phase noise.

They have a four point mount with excellent heat transfer properties making them ideal for OCXO designs with a good vibration and low G sensitivity requirements. Additionally, the SMX-8 has excellent thermal transfer properties and a low Q which can improve levels of thermal perturbations. They can be ordered with a high temperature option, the SMP-8 up to 250C and the SMX-8 up to 300C.

SMP-8 and SMX crystals are ideally suited for use in satellite and data communication applications.

Uniquely there is the option of adding a thermistor internally. This improves the accuracy and speed of the thermal feedback circuit when used in a TCXO. The option also may have advantages in OCXO applications. The chip thermistor and wire combination allow thermal measurement in very close proximity to the crystal itself.
