Crystals Applications

• Hearing aids requiring compact frequency sources
• Earbuds with limited internal volume constraints
• Wireless communication devices needing precise clock signals

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tolerance specifications. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Check for any Class III life-supporting device restrictions if used in medical equipment. Ensure supply chain stability due to reported order volume impacts on delivery times.

Crystals Selection Notes

Select this component when a miniature quartz crystal is required for hearing aids or earbuds. The 8 pF load capacitance must match the oscillator circuit design. Verify the ±50 ppm tolerance meets system accuracy needs. Consider the 40 Ohm ESR for drive level limitations. Ensure the operating temperature range aligns with the application environment.
