Big Capacity Made by an advanced LBA foaming material to ensure its superior thermal insulation effect, this new chest freezer has a bigger capacity compared to normal ones. |
360° Cooling D-type cooling pipe, which has more surface contact with the cabinet, is adopted for this product and has realized more efficient heat exchange between the inner wall and the evaporate pipe. |
Keep for 135H This new chest freezer is able to keep the inside temperature staying on 0 ℃ for 135 hours after powering off. . |
Removable Basket The movable basket provides 2 choices for you. You can either put it in the chest freezer or take it out. Another convenient design for you. |
The FC-55DD4SAA is a high-precision crystal oscillator engineered for applications requiring stable and accurate frequency control. First of all, it provides exceptional frequency stability, even under changing temperature and voltage conditions. Moreover, its compact design allows for seamless integration into space-limited circuit boards. In addition, the device supports a wide frequency range, offering flexibility across various system designs.
Not only that, the FC-55DD4SAA features low phase noise, which enhances signal clarity in sensitive communication systems. Meanwhile, its low power consumption makes it ideal for battery-operated devices. Furthermore, it maintains reliable performance over long operational lifespans.
