The component utilizes a through-hole mounting configuration with an insertion loss of 2.5 dB and a bandwidth of 15 kHz.

Feature Summary

• Monolithic crystal construction for stable frequency filtering
• Through-hole package design for standard PCB integration

Applications

• Cellular communication systems
• WiFi signal processing
• Power supply frequency control

Procurement Notes

Verify the specific suffix 'F30IL02AK' or 'F30IL02A' against official manufacturer documentation to ensure exact electrical parameter matching, as minor suffix variations may indicate different tolerance or packaging specifications. Confirm the 2.2 kOhms series resistance requirement aligns with the target circuit design before procurement.

Selection Notes

Select this component when a 21.4 MHz center frequency with 15 kHz bandwidth is required for cellular or WiFi applications. Ensure the circuit supports the specified 2.2 kOhms series resistance and 2.5 dB insertion loss characteristics. Verify that the through-hole form factor fits the available board space and assembly process constraints.
