Crystals Procurement Notes

Verify the specific suffix '28A' against official ECS documentation to confirm the exact tolerance and ESR specifications. Ensure the ordering code matches the required RoHS compliance status and tape-and-reel packaging format. Cross-reference the manufacturer's latest datasheet to validate current production status and any potential obsolescence notices before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 16 MHz reference with ±30 ppm initial accuracy is required. The 20 pF load capacitance must match the oscillator circuit design parameters. Consider the HC-49/US SMD form factor for space-constrained PCB layouts. Verify that the operating temperature range of -10 °C to +70 °C meets the environmental requirements of the target application.
