Procurement Notes

Verify the specific ordering suffix to ensure the correct tape-and-reel quantity and ESD protection level match your production requirements. Confirm that the SC-70FL/MCPH3 package dimensions align with your PCB footprint design. Check for RoHS compliance documentation if required by your regulatory standards. Ensure the supplier provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component when a dual varactor configuration is needed for balanced tuning or differential signal paths in FM receivers. The low capacitance value at nominal bias makes it suitable for higher frequency tuning ranges. Consider the thermal characteristics and power dissipation limits relative to the expected operating conditions in the target application environment.

Part Context

This part belongs to Sanyo's series of varactor diodes optimized for radio frequency tuning. The twin-diode architecture allows for compact designs compared to using discrete single units. It serves as a critical passive component in analog front-end circuits where precise frequency control via voltage variation is essential for stable reception performance.
