2N4340 +BOM

JFET N-Channel 50 V 325 mW Through Hole TO-18

2N4340 Information

Description

The 2N4340 is a JFET (Junction Field-Effect Transistor) transistor, specifically an N-channel device packaged in the TO-18 (3-pin) package. It's manufactured by Interfet. As an N-channel JFET, it operates by controlling current flow between two electrodes (source and drain) using a voltage applied to a third electrode (gate). This allows for amplification or switching of electronic signals. The 2N4340 is suitable for various applications, including audio equipment, radio frequency (RF) circuits, and general-purpose electronics. Its characteristics make it useful for tasks such as impedance matching, signal amplification, and voltage regulation. In summary, the 2N4340 is a versatile N-channel JFET transistor designed for use in a wide range of electronic devices and systems.

Package

The 2N4340 JFET Transistor from Interfet has a TO-18 (TO18-3) package type, which is a three-lead can package commonly used in discrete transistor applications.

Manufacturer

According to the product information, the manufacturer of the 2N4340 is Interfet.
