The LCR-T4 Tester transistor condensadores ESR is an essential tool for technicians and electronics enthusiasts who need to carry out accurate and fast measurements of electronic components. This compact and easy-to-use unit can identify and measure bipolar transistors (NPN, PNP), MOSFETs (N-channel and P-channel), JFETs, diodes, thyristors, capacitors, inductances and resistances with great precision.
Main features:
- One-button operation and automatic shut-off for energy saving.
- Low shut-off current of 20nA, ensuring accurate measurements without damaging components.
- Automatic detection of bipolar transistors, MOSFET, JFET, diodes, one-way and two-way thyristors.
- Automatic identification of component pin layout.
- Measurement of current gain factor (hFE) and base-emitter threshold voltage for bipolar transistors.
- Recognition of Darlington transistors through voltage and gain analysis.
- Detection of protection diodes in MOS transistors.
- Measurement of threshold voltage and gate capacitance in MOSFETs.
- Simultaneous measurement of two resistors with symbol and pin number indication, ideal for potentiometers.
- High-resolution resistance measurement from 0.1 ohmios to 50M ohmios.
- Capacitance measurement from 30pF to 100mF with 1pF resolution.
- Simultaneous measurement of equivalent series resistance (ESR) in capacitors over 2uF with 0.01 ohmios resolution.
- Accurate identification of diodes, LEDs and Zener diodes with forward and reverse breakdown voltage measurement.
- Reverse capacitance measurement in diodes and connected bipolar transistors.
- Easy measurement of bridge rectifiers with a single connection.
Typical uses:
This tester is ideal for electronics technicians, engineers and hobbyists who need to quickly check the condition and characteristics of electronic components in circuits, repairs and prototype development.

Customer Questions & Answers
What are the dimensions, weight and main materials of the tester? What is included in the box?
The Lcr-T4 typically measures 70 x 90 x 28 mm and weighs around 70 g. The main body is made of ABS plastic with an integrated LCD screen. The box usually includes the Lcr-T4 module, transistor socket, and connectors or cables, but the contents may vary by supplier; please check the exact listing before buying.
What type of power supply does it require and are there any requirements for correct operation?
The tester works with a standard 9 V battery (type 6F22/PP3). Its power consumption is very low (only 20 nA in standby), but reliable measurement requires the battery to supply at least 7 V. It is not compatible with external power supplies or higher voltages, to avoid damage to the circuit.
What are the common errors or issues when using the Lcr-T4 and how can they be solved?
Common issues include erratic results due to poor contact on the pins, a low battery, or components outside the measurement range. To resolve this, ensure the terminals are clean and making firm contact, replace the battery if the display becomes unstable, and check that the component being measured is within the device’s range.
What are the objective differences between this tester and a conventional advanced digital multimeter?
Unlike a digital multimeter, the Lcr-T4 automatically identifies the component and pin configuration, and also measures advanced parameters such as ESR, MOSFET Vth and BJT hFE, without needing manual range selection. However, it does not measure voltage/current in circuit and its accuracy is lower than that of an advanced professional multimeter.
What types of transistors can the LCR-T4 Tester detect?
It can detect NPN and PNP bipolar transistors, N-channel and P-channel MOSFETs, as well as JFETs.
Does the tester measure capacitance and resistance?
Yes, it measures capacitance from 30pF to 100mF and resistance from 0.1 ohmios to 50M ohmios with high accuracy.
How is a Darlington transistor identified with this tester?
The tester measures the threshold voltage and high current gain factor to identify Darlington transistors.
Does the device have automatic shut-off?
Yes, it has automatic shut-off to conserve battery when not in use.
Can it measure the equivalent series resistance (ESR) of capacitors?
Yes, it can measure capacitance and equivalent series resistance (ESR) simultaneously in capacitors larger than 2uF.
