Crystals Procurement Notes

Verify current availability status as the product has been marked as obsolete by the manufacturer. Confirm end-of-life notifications and check for authorized distributors holding remaining stock. Ensure compliance with RoHS3 requirements for environmental regulations before procurement.

Crystals Selection Notes

Select this component when a 18.432 MHz reference signal is required in a compact 5.0x3.2mm footprint. Consider the 20pF load capacitance compatibility with host circuit designs. Evaluate the ±20ppm stability against system timing accuracy requirements within the specified -40°C to +85°C operational envelope.

Crystals Part Context

This part belongs to the TXC 7B series of miniature crystals. It serves as a passive frequency control element distinct from active oscillators like the 7X series. The 7B series provides standard timing solutions for embedded applications requiring stable clock references in space-constrained environments.
