Crystals Procurement Notes

Verify the specific load capacitance and frequency tolerance against circuit design requirements before integration. Confirm that the 4-SMD package dimensions align with the printed circuit board layout constraints. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the datasheet specifications to guarantee compatibility with the intended oscillator circuit topology.

Crystals Selection Notes

Select this component when a 26.0 MHz reference signal is required in ultra-compact form factors. The 10 pF load capacitance suits standard oscillator circuits without additional external capacitors. Consider the ±10 ppm tolerance for general-purpose timing rather than high-precision navigation systems. The wide temperature range supports operation in diverse consumer electronics environments.
