Procurement Notes
Verify the specific ordering suffix /TR against the manufacturer's current datasheet to confirm tape and reel packaging requirements. Ensure the SOT-23-3 footprint matches the target PCB layout. Cross-reference the 30 V reverse voltage rating with system operating conditions to prevent breakdown during peak signal swings.
Selection Notes
Select this component when a compact SOT-23-3 form factor is required for RF tuning applications. The specified Q factor of 2500 at 50 MHz supports high-frequency performance needs. Verify that the 2.7 pF baseline capacitance aligns with the circuit's impedance matching requirements at the intended operating frequency.
