7M-33.8688MAHV-T

Crystals Overview

The 7M-33.8688MAHV-T is a surface-mount quartz crystal resonator manufactured by TXC Corporation, designed for precision timing applications. It operates at a fundamental frequency of 33.8688 MHz with an initial frequency tolerance of ±30 ppm at 25°C and a total frequency stability of ±30 ppm across the industrial temperature range of -40°C to +85°C. The component features a load capacitance of 8 pF and an equivalent series resistance (ESR) of 50 Ohms. Housed in a compact 3.2 mm x 2.5 mm x 0.8 mm ceramic package with four solder pads, it utilizes a seam-seal construction suitable for automated SMD/SMT assembly.

Crystals Feature Summary

• Seam-seal ceramic construction provides robust environmental protection and long-term reliability.
• Industrial-grade temperature stability ensures consistent performance from -40°C to +85°C.
• Compact 4-SMD footprint facilitates high-density PCB layout and automated placement.

Crystals Applications

• Microcontroller clock sources requiring precise timing synchronization
• Communication interfaces utilizing standard baud rates derived from 33.8688 MHz
• Automotive electronic control units demanding stable oscillator references

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact electrical parameters and packaging specifications. Ensure compatibility with the target circuit's load capacitance requirements before procurement. Confirm that the requested quantity aligns with the standard reel packaging size to avoid partial reel handling issues during assembly.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for cost-sensitive designs needing moderate stability. The 8 pF load capacitance matches common oscillator IC configurations. Consider the 50 Ohm ESR limit to ensure adequate drive level margins within the host circuit design constraints.

Crystals Part Context

This part belongs to the 7M series of MHz quartz crystals, characterized by small form factors and ceramic packages. It serves as a passive frequency-determining element, distinct from active oscillators. The series supports various frequencies optimized for digital logic and serial communication standards.

Crystals Replacement Considerations

Direct substitutes must match the 33.8688 MHz frequency, 8 pF load capacitance, and 3.2x2.5mm package dimensions. Verify that alternative components meet the same ±30 ppm stability and -40 to +85°C operating range specifications.
