12.95028

Overview

The Geyer Electronic America, Inc. model 12.95028 is a ceramic surface-mount oscillator designed for frequency control applications. It operates at a nominal frequency of 12 MHz with an HCMOS output signal. The device features a load capacitance of 15 pF and a duty cycle of 60%. It functions on a single 3.3 V supply voltage and provides a frequency stability of ±50 ppm. The component is housed in a compact 4-pin SMD package and is supplied in tape and reel format for automated assembly processes.

Feature Summary

• Generates stable HCMOS clock signals for digital circuit synchronization
• Utilizes ceramic resonator technology for reliable frequency generation
• Designed for direct surface-mount integration into printed circuit boards

Applications

• Microprocessor clock source generation
• Digital communication interface timing
• Embedded system clock distribution

Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and tape-and-reel quantity match project requirements. Confirm that the 3.3 V operating voltage aligns with the target system power rails. Check the lead time against production schedules as standard availability may vary. Ensure the 12 MHz frequency specification meets the design constraints before finalizing procurement orders.

Selection Notes

Select this component when a low-cost, ceramic-based oscillator solution is required for non-critical timing applications. The HCMOS output level is suitable for standard logic families operating at 3.3 V. Consider the ±50 ppm stability limit when evaluating compatibility with the receiving device's clock tolerance requirements. Verify physical footprint compatibility with the PCB layout constraints.

Part Context
