12.88655

Crystals Overview

The Geyer Electronic America, Inc. model 12.88655 is a ceramic surface-mount crystal oscillator designed for frequency control applications. It operates at a fundamental frequency of 30 MHz with a load capacitance of 16 pF and an equivalent series resistance of 50 Ohms. The component features a 4-SMD, no-lead package configuration suitable for automated assembly processes. Frequency stability is specified at ±100 ppm across the operating temperature range of -40°C to +85°C.

Crystals Feature Summary

• Surface-mount construction with four solder pads for reliable PCB attachment
• Fundamental mode operation providing stable frequency generation
• Wide operating temperature range supporting industrial environments

Crystals Applications

• Clock signal generation in microprocessor systems
• Frequency reference sources for communication modules
• Timing circuits in consumer electronic devices

Crystals Procurement Notes

Verify the specific lot code and date code upon receipt to ensure compliance with project timelines. Confirm that the delivered components match the 4-SMD no-lead package specification. Check for any physical damage to the ceramic body or solder pads before integration into the manufacturing line. Ensure storage conditions adhere to manufacturer guidelines to maintain component integrity.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency is required with moderate stability needs. The 16 pF load capacitance must align with the host circuit's design parameters. Consider the 50 Ohm ESR for impedance matching requirements. The wide temperature range makes it suitable for applications exposed to varying environmental conditions without requiring additional thermal compensation.

Crystals Part Context

This part belongs to Geyer Electronic's family of ceramic SMD crystals. These components are manufactured using piezoelectric ceramic materials rather than quartz, offering cost-effective solutions for mass-produced electronics. The 4-SMD form factor allows for compact board layouts and high-volume surface-mount technology processing.

Crystals Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 16 pF load capacitance, and 4-SMD package dimensions. Verify that alternative components meet the same ±100 ppm stability and -40°C to +85°C temperature range specifications. Ensure the replacement part has comparable ESR characteristics to maintain circuit performance.
