603-12-67

Crystals Overview

The Fox Electronics 603-12-67 is a surface-mount quartz crystal resonator designed for frequency control applications. It operates at a fundamental frequency of 12.0000 MHz with a load capacitance of 20 pF and a frequency tolerance of ±50 ppm. The component features an equivalent series resistance of 150 Ohms and is housed in a 4-SMD, No Lead package, specifically a DFN or LCC form factor. It supports an operating temperature range from -10°C to +60°C and complies with RoHS standards for lead-free manufacturing.

Crystals Feature Summary

• Surface mount construction utilizing a 4-terminal no-lead DFN/LCC package design
• Fundamental mode quartz crystal operation at 12 MHz
• RoHS compliant lead-free manufacturing process

Crystals Applications

• General purpose clock signal generation in embedded systems
• Microcontroller oscillator circuits requiring stable timing references
• Consumer electronics devices with surface mount assembly requirements

Crystals Procurement Notes

Verify the specific package variant (DFN vs LCC) against the mechanical drawing before integration. Confirm that the ±50 ppm tolerance meets the system timing budget. Ensure the operating temperature range of -10°C to +60°C aligns with the final product environment. Check for any specific handling sensitivity associated with the surface-mount crystal structure during reflow processes.

Crystals Selection Notes

Select this component when a 12 MHz surface-mount crystal with moderate stability is required. The 20 pF load capacitance must match the oscillator circuit design. Consider the limited temperature range if the application extends beyond standard commercial limits. The 150 Ohm ESR should be compatible with the driving capability of the host oscillator IC.

Crystals Part Context

This part belongs to Fox Electronics' standard line of surface-mount quartz crystals. The manufacturer specializes in frequency control products including oscillators and resonators for telecommunications and industrial sectors. The 603 series represents a common family of SMD crystals offering various frequencies and package options for general electronic designs.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz SMD crystals with identical 20 pF load capacitance and similar footprint dimensions. Verify pin compatibility and electrical parameters such as ESR and tolerance when evaluating alternative manufacturers. Cross-reference with Fox's own portfolio for updated revisions or enhanced performance variants.
