This listing is for five (5) 2N5770 NPN silicon RF transistors in a TO-92 through-hole package. Designed for high-frequency, low-noise performance, the 2N5770 is ideal for RF amplification, signal processing, and switching in VHF and UHF circuits. With a typical transition frequency of 800 MHz and a collector-emitter voltage of 30V, it's perfect for low-level RF stages in radios, receivers, and communication equipment. Manufactured by National Semiconductor. These are new and unused components—ready for your next RF project or repair.
