AS-8.000MAHK-B

Crystals Overview

The AS-8.000MAHK-B is a through-hole MHz crystal manufactured by TXC Corporation. It operates at a nominal frequency of 8 MHz with a frequency stability and tolerance of ±30ppm. The component features a load capacitance of 20pF and an equivalent series resistance (ESR) of 80 Ohms. It is housed in an HC-49/US package, measuring 11.50mm in length and 5.00mm in width. This crystal is designed for general clock timing applications requiring reliable frequency generation.

Crystals Feature Summary

• Through-hole mounting configuration for robust mechanical attachment
• Standard HC-49/US package format for widespread compatibility
• Stable frequency output with ±30ppm tolerance

Crystals Applications

• General purpose clock timing circuits
• Microcontroller system oscillators
• Embedded device frequency references

Crystals Procurement Notes

Verify the specific manufacturing date code and lot traceability requirements against your quality management standards before finalizing orders. Ensure that the HC-49/US footprint dimensions align precisely with your PCB design constraints. Confirm that the 80 Ohm ESR specification is compatible with your oscillator circuit design to guarantee stable startup and operation under all expected environmental conditions.

Crystals Selection Notes

Select this component when a through-hole crystal is required for 8 MHz applications. The HC-49/US package offers mechanical durability suitable for environments where surface-mount options may be less desirable. The ±30ppm stability is adequate for standard digital logic and microcontroller systems that do not require high-precision timing sources provided by oven-controlled or TCXO alternatives.

Crystals Part Context

This part belongs to the standard crystal category within TXC Corporation's portfolio. It serves as a fundamental passive component for generating precise clock signals in electronic circuits. Unlike active oscillators, it requires an external oscillator circuit to function. The HC-49/US form factor remains a legacy but widely used standard in various industrial and consumer electronics assemblies.

Crystals Replacement Considerations

Direct replacements must match the 8 MHz frequency, 20pF load capacitance, and HC-49/US package dimensions. Verify that substitute parts maintain the same ±30ppm stability and 80 Ohm ESR characteristics to ensure circuit compatibility without redesigning the surrounding oscillator components.
