2N4401 & 2N4403 Transistor Development Kit (#2025)

This is the Transistor Prototype PCB Design Kit with 2N4401 & 2N4403 Transistors. This kit is what you need to develop numerous different transistor circuits. It includes the extremely useful NightFire Prototype Transistor PCB along with some of the very popular 2N4401 NPN & 2N4403 PNP Transistors in the standard leaded TO-92 package. You will also get a blank Prototype PCB with 162 holes, also designed by us, to expand your circuits.

The PCB is designed for different types of biasing with outputs at several points in the circuit. With this kit, you can build transistor switches, audio amplifiers, buffers, level shifters, logic gates, emitter followers, and much more, such as, single-transistor guitar effects circuits. This Prototype PCB can be used for NPN, PNP, FETs, MOSFETs, SCRs, and more. Simply populate the components that you need.

You will also get different common values of 1/4 Watt, Carbon Film 5% Resistors, Ceramic Capacitors, Inductors, Signal & Power & Zener Diodes, Trimpots, LEDS, an Electret Microphone, a miniature Speaker , Pushbutton Switches, and a Battery Clip. This kit has 166 total pieces. There are NO SMT components in this selection; all components are Thru-Hole. All this comes in a Plastic Box that can serve as a Project Box as well.

The Prototype PCB is 1.13" x 2.0" made of FR-4 material, 0.062", with all holes plated-thru. The Blank Perf-Board is 1.14" x 2.10" and it made of FR-4 material, 0.062", with 162 Plated Thru-Holes. There are enough different parts to build many different types of transistor circuits. Search the web for incredible circuits to build. The Datasheets and Application Notes for the Transistors, along with hundreds of others, are located at DATASHEETS. We supply the parts, you supply the ingenuity. You get the following:
