TO18 Small Signal Transistor Central 2N2368 PBFREE Suitable for RF IF Oscillation and Amplification Needs
Small Signal Transistors - TO-18 Case
Central Semiconductor offers a range of small signal transistors in the TO-18 case, designed for various applications including RF/IF oscillation, amplification, switching, and low-noise operations. These transistors are characterized by key electrical parameters such as breakdown voltages (BVCBO, BVCEO, BVEBO), leakage current (ICBO), DC current gain (hFE), saturation voltage (VCE(SAT)), output capacitance (Cob), transition frequency (fT), noise figure (NF), and switching times (ton, toff). The product line includes both NPN and PNP types, catering to diverse circuit designs.
