7M-50.000MDHV-T

Crystals Overview

The TXC Corporation 7M-50.000MDHV-T is a parallel fundamental quartz crystal designed for surface-mount applications. It operates at a nominal frequency of 50 MHz with an 8 pF load capacitance. The component features a 4-pin SMD package without leads, measuring 2.5 mm in length, 2.0 mm in width, and 0.75 mm in height. It provides a frequency tolerance of ±20 ppm at 25°C and maintains stability within ±30 ppm across the operating temperature range of -40°C to +85°C. The series resistance is specified at 80 Ω, and the drive level is limited to 1 µW.

Crystals Procurement Notes

Verify the exact part number suffix against official manufacturer documentation, as variations such as MAHV or MDHV may indicate differences in packaging or specific parameter tolerances not explicitly detailed in general listings. Confirm availability status through authorized distributors, as supply constraints may affect immediate procurement. Ensure that the selected variant matches the required load capacitance and frequency stability specifications for the target application circuit design.

Crystals Selection Notes

Select this component when a compact 4-pin SMD footprint is required for high-frequency timing applications. The 50 MHz frequency and 8 pF load capacitance are suitable for standard microcontroller clock inputs. Consider the 80 Ω series resistance and 1 µW drive level limits to ensure compatibility with the oscillator circuit's power requirements. The wide temperature range supports operation in diverse environmental conditions typical of automotive and industrial electronics.
