7V-50.000MDDQ-T

Crystals Overview

The 7V-50.000MDDQ-T is a 50 MHz fundamental mode quartz crystal manufactured by TXC Corporation. It features a frequency tolerance and stability of ±20 ppm with a load capacitance of 10 pF. The equivalent series resistance (ESR) is specified at 60 Ohms. This component utilizes a 4-SMD, no-lead package measuring 3.2 mm in length, 2.5 mm in width, and 0.8 mm in height. It operates within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Fundamental resonance mode operation for precise frequency generation
• Compact surface-mount design suitable for space-constrained PCB layouts
• Automotive-grade reliability certification ensuring performance under varying thermal conditions

Crystals Applications

• Automotive electronic systems requiring AEC-Q200 compliant timing components
• Microcontroller clock sources in industrial control units
• Communication modules needing stable 50 MHz reference signals

Crystals Procurement Notes

Verify the specific suffix 'D' indicates automotive grade qualification against standard commercial variants. Confirm package dimensions match the target footprint exactly, as slight variations exist between similar TXC series. Ensure the supply chain source provides valid RoHS compliance documentation consistent with current environmental regulations.

Crystals Selection Notes

Select this component when a 50 MHz fundamental crystal with ±20 ppm stability is required for automotive or high-reliability applications. Compare ESR values against the oscillator circuit requirements to ensure proper startup. Consider the 10 pF load capacitance compatibility with the host device's internal capacitors to maintain frequency accuracy.

Crystals Part Context

This part belongs to the 7V series of quartz crystals from TXC Corporation, which are designed for automotive and industrial markets. Unlike the 7M series, the 7V series typically adheres to stricter automotive standards such as AEC-Q200. It serves as a passive timing element distinct from active oscillators like the BB or AU series.

Crystals Replacement Considerations

Direct substitutes include other AEC-Q200 qualified 50 MHz crystals with identical 3.2x2.5mm footprints and 10pF load capacitance. Verify that alternative parts meet the same ±20 ppm tolerance and 60 Ohm ESR specifications to ensure circuit compatibility without redesign.
