12.88681

Crystals Overview

The Geyer Electronic America, Inc. model 12.88681 is a quartz crystal component designed for frequency control applications. It operates at a fundamental frequency of 26 MHz with a specified tolerance of ±10ppm. The device features a load capacitance of 16pF and an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Crystals Feature Summary

• Super ultra-miniature footprint design ideal for space-constrained environments
• Quartz crystal construction for stable frequency generation
• Surface-mount compatible packaging for automated assembly

Crystals Applications

• Hearing aids
• Earbuds
• Wireless applications

Crystals Procurement Notes

Verify the specific ordering suffix against the official Geyer Electronic America datasheet to ensure correct frequency and tolerance specifications. Confirm that the 4-SMD No Lead package matches your PCB footprint requirements. Check for Class III Life Supporting Device classification if used in medical contexts. Ensure compatibility with your reflow soldering profile for leadless components.

Crystals Selection Notes

Select this component when a 26 MHz reference signal is required in miniaturized wearable or audio devices. The 16pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level sensitivity. The super ultra-miniature form factor is critical for hearing aid and earbud integration where board space is limited.

Crystals Part Context

This part belongs to the KX-2 series from Geyer Electronic America, known for super ultra-miniature quartz crystals. The series targets high-density electronics requiring precise timing in small packages. It complements the manufacturer's broader portfolio of oscillators and resonators for frequency control needs.
