Price increased on 8/1/22. The cost of semiconductors continues to increase. Factory lead-times are 78 weeks; however, we made a significant investment in these parts and our stock will not last long. The SD2942 is still a popular and reliable part that is still being used in FM transmitters around the world.

Original factory ST part. May be used as replacement for BLF278.
