Description

Schmitt Trigger SMD Trainer

This kit is part of the SMD Trainer range that only uses SMD parts to test out your soldering skills. Consisting of just two transistors, two capacitors, two LEDs, and four resistors, you will be able to create a dual LED flasher, and this kit is based on the MitchElectronics Transistor Flasher Kit, just a lot smaller. Before making this kit, be sure to read our SMD soldering guide found in our resources page, and pay extra attention when positioning components because de-soldering SMD parts can be extremely challenging.

Applications

The Schmitt Trigger SMD Trainer is an excellent kit for testing soldering skills, especially with the potentiometers and the MMBT3904 transistor (as these are very small). Regarding practical applications, this small module is great for conditioning signals such as level sensors, fill levels, and photodiodes so that varying analogue signals become a single logical on or off. The use of hysteresis means that small signal changes are ignored, thereby preventing circuits from going crazy when the input value crosses a threshold.

Notes

Note that product specifics such as output frequency depend on the tolerance of the components. The numbers provided here are an approximation only. Also take note that the estimated delivery is not guaranteed (unless special delivery is chosen) and free delivery has a maximum waiting time of two weeks. Any product that is returned which is built using lead solder is ineligible for a refund. 

All parts sold by MitchElectronics are compliant with RoHS and REACH directives which ensure that they can be used in commercial environments as well as complying with environmental laws.
