F.E.T. Characteristics Apparatus Trainer Kit – Study JFET Drain & Transfer Characteristics

Gain hands-on experience with Field-Effect Transistor (FET) behaviour using this professionally designed F.E.T. Characteristics Apparatus Trainer Kit. Built around the popular BFW10 N-channel JFET, this self-contained unit enables students to accurately plot drain characteristics (ID vs VDS) and transfer characteristics (ID vs VGS) — essential experiments for any electronics or electrical engineering curriculum.

What's in the Box

• Sturdy blue metal enclosure with clearly silk-screened front panel
• Analog Voltmeter 1 — 5V DC (Gate-Source voltage, VGS measurement)
• Analog Ammeter — 15mA DC (Drain current, ID measurement)
• Analog Voltmeter 2 — 15V DC (Drain-Source voltage, VDS measurement)
• Dual independent DC power supplies:
  • VGS supply: 0–4V DC (adjustable via potentiometer)
  • VDS supply: 0–19V DC (adjustable via potentiometer)
• Built-in BFW10 N-channel JFET on the circuit board
• Clearly printed circuit diagram on the panel for easy reference
• MAINS ON/OFF power switch with indicator
• Banana plug terminals (red/black) for all measurement points
• Set of patch cords (red and black banana plug cables)

Key Features

• Plot drain (output) characteristics: ID vs VDS at constant VGS
• Plot transfer (mutual) characteristics: ID vs VGS at constant VDS
• Determine key FET parameters: Transconductance (gm), Drain resistance (rd), and Amplification factor (μ)
• Three large, easy-to-read analog panel meters for simultaneous monitoring
• Compact and rugged design for repeated lab use
• Ideal for ECE, EEE, and Physics practical labs

Experiments You Can Perform

• Plot drain (output) characteristics of N-channel JFET (BF245)
• Plot transfer (mutual) characteristics of N-channel JFET
• Calculate transconductance (gm), drain resistance (rd), and amplification factor (μ)
• Study ohmic, saturation (pinch-off), and cut-off regions of FET operation
• Understand the concept of pinch-off voltage and IDSS

Perfect For

Engineering and polytechnic students (ECE/EEE/Physics), ITI labs, science colleges, and electronics hobbyists seeking a reliable, ready-to-use platform for FET characterisation experiments.
