7V-45.000MDDV-T

Crystals Overview

The TXC Corporation 7V-45.000MDDV-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 45 MHz. It features an 8 pF load capacitance and offers a frequency tolerance and stability of ±20 ppm across the commercial temperature range of -20°C to +70°C. The component utilizes a 4-SMD, no-lead package with dimensions of 3.2 mm in length, 2.5 mm in width, and 0.8 mm in height. Key electrical characteristics include a maximum equivalent series resistance (ESR) of 60 Ohms and a recommended drive level of 10 uW. This device is designed for precision timing applications requiring compact form factors.

Crystals Procurement Notes

Verify that the specific ordering suffix matches the required load capacitance and tolerance specifications for your circuit design. Confirm that the supply chain source provides genuine components from TXC Corporation to ensure reliability. Check for any recent product lifecycle notifications or discontinuance alerts prior to finalizing procurement plans. Ensure compatibility with automated pick-and-place equipment due to the small SMD package size.

Crystals Selection Notes

Select this component when a 45 MHz reference is required with tight frequency stability constraints. The 8 pF load capacitance must match the oscillator circuit requirements specified by the host device. Consider the 60 Ohm ESR limit to ensure proper oscillation startup and sustainment. Evaluate the thermal performance against the -20°C to +70°C operational window to guarantee long-term accuracy in the intended environment.
