Procurement Notes

Verify end-of-life status through official manufacturer notifications before finalizing design implementations. Confirm that the specific suffix corresponds to the required packaging format, as variations may exist between reel and cut tape options. Ensure compliance with current environmental regulations such as RoHS3 and REACH requirements for the target market.

Selection Notes

Select this component when a 10.7 MHz center frequency with 150 kHz bandwidth is required for FM applications. The 330 Ohm impedance must match the circuit design specifications. Consider the 1412 package dimensions for PCB layout constraints. Verify that the 6dB insertion loss aligns with system sensitivity requirements.
