Crystals Procurement Notes

Verify that the specific suffix BF18-30 aligns with your required load capacitance and tolerance specifications. Confirm the 40 Ohm maximum series resistance meets your circuit impedance requirements. Ensure the Tape & Reel quantity matches your production line capacity. Cross-reference the manufacturer part number to avoid confusion with similar HC-49 variants.

Crystals Selection Notes

Select this component when a standard HC-49/US footprint is required for surface-mount applications. The 19.456 MHz frequency is suitable for communication protocols requiring precise timing. The 18 pF load capacitance must match the oscillator input pins of the target device. Consider the 40 Ohm resistance limit for low-power drive level designs.
