8Y-40.000MAAJ-T

Crystals Overview

The TXC Corporation 8Y-40.000MAAJ-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 40 MHz. It features an 18 pF load capacitance and a frequency tolerance of ±30 ppm at 25°C. The component supports a frequency stability of ±30 ppm across the industrial temperature range of -20°C to +70°C. Designed for compact electronics, it utilizes a 4-SMD, No Lead package with dimensions of 3.2 mm in length, 2.5 mm in width, and 0.55 mm in height.

Crystals Feature Summary

• Utilizes SC-cut quartz technology for enhanced frequency stability
• Designed for low-profile surface-mount assembly applications
• Provides reliable oscillation within specified industrial temperature limits

Crystals Applications

• Precision timing circuits in consumer electronics
• Clock generation for microcontrollers and processors
• Communication module synchronization systems

Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official documentation to ensure correct tolerance and packaging specifications. Confirm that the required load capacitance matches the target circuit design parameters before procurement. Check current availability status as supply levels may fluctuate. Ensure compliance with relevant environmental directives such as RoHS requirements applicable to your region.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with moderate stability over a limited temperature range. The 18 pF load capacitance must align with the oscillator circuit's input and output capacitance values. Consider the physical footprint constraints of the PCB layout. Evaluate if the ±30 ppm tolerance meets the system's jitter and phase noise requirements compared to higher-grade alternatives.

Crystals Part Context

This part belongs to the 8Y series of quartz crystals manufactured by TXC Corporation. The series focuses on standard frequency components suitable for general-purpose timing applications. The 8Y designation indicates specific dimensional and electrical characteristics distinct from other TXC product lines like the 7M or 8Z series. This model represents a balance between performance and cost for mass-produced electronic devices.

Crystals Replacement Considerations

The 7M-40.000MAAJ-T is a documented parameter-equivalent alternative from the same manufacturer. Verify pin compatibility and mounting dimensions before substitution. Ensure the replacement part meets the same electrical specifications for load capacitance and frequency stability.
