Procurement Notes

Verify the specific suffix BKBK against official QST documentation to confirm pin configuration and termination type. Ensure the selected variant matches the required load capacitance of 20pF for circuit compatibility. Cross-reference the MSL rating and RoHS status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a 30 MHz fundamental frequency with ±50ppm stability is required. Consider the 40 Ohm ESR and 20pF load capacitance for oscillator circuit design. Evaluate the 4-SMD package size against board space constraints. Confirm that the operating temperature range meets the environmental conditions of the target application.
