Procurement Notes
Verify the specific suffix OE against official Mercury Electronics documentation to confirm exact electrical characteristics and pinout configuration. Ensure the operating temperature range meets application requirements. Confirm RoHS compliance status through manufacturer datasheets prior to integration into final products.
Selection Notes
Select this component when a low-profile 2.0x1.6mm footprint is required for space-constrained designs. The 1.8V supply voltage makes it suitable for modern low-power digital systems. Consider the enable/disable feature if power management during idle states is necessary for the target application.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies including 37.2 MHz and 37.888 MHz variants. These oscillators are characterized by their small form factor and standard LVCMOS outputs, targeting consumer electronics and portable devices.
Replacement Considerations
Direct substitutes include other 18QHTF21 series parts with matching frequencies or compatible packages such as the 18QHTF21-7.37283-PD variant which shares similar physical dimensions and electrical parameters.
