12.85562

Crystals Overview

The Geyer Electronic America, Inc. part number 12.85562 is a surface-mount quartz crystal designed for frequency control applications. It operates at a fundamental frequency of 50 MHz with a specified load capacitance of 8 pF. The component exhibits a frequency tolerance of ±30 ppm and possesses an equivalent series resistance of 80 Ohms. It is housed in a compact 4-SMD, no-lead package suitable for automated assembly processes.

Crystals Feature Summary

• Surface-mount quartz crystal construction
• Fundamental frequency operation at 50 MHz
• Integrated 8 pF load capacitance specification
• Compact 4-SMD no-lead package design

Crystals Applications

• General clock signal generation
• Microcontroller timing circuits
• Embedded system frequency references
• Consumer electronics timing modules

Crystals Procurement Notes

Verify the specific load capacitance requirement of your circuit against the 8 pF specification to ensure accurate frequency performance. Confirm that the 4-SMD no-lead package dimensions are compatible with your PCB footprint and reflow soldering profile. Ensure the ±30 ppm tolerance meets the timing accuracy requirements of your target application before finalizing procurement.

Crystals Selection Notes

Select this component when a 50 MHz reference is required in a small form factor. The 8 pF load capacitance must match the oscillator circuit design to achieve the nominal frequency. Consider the ±30 ppm tolerance relative to system timing constraints. The SMD package facilitates high-volume manufacturing integration compared to through-hole alternatives.

Crystals Part Context

This component belongs to the quartz crystal category manufactured by Geyer Electronic America, Inc. It serves as a passive frequency control element within electronic assemblies. Unlike active oscillators, it requires an external oscillator circuit to generate a square wave output. It provides stable frequency determination for digital logic interfaces.

Crystals Replacement Considerations

Substitutes must match the 50 MHz frequency, 8 pF load capacitance, and 4-SMD package type. Verify that alternative components offer equal or better tolerance specifications relative to the ±30 ppm baseline. Ensure compatibility with existing PCB footprints and thermal profiles during replacement.
