Transistor - NPN (BC337)
The BC337 is an NPN silicon bipolar junction transistor (BJT) suitable for switching and amplification in general-purpose circuits. With a collector current rating of 800 mA and a collector-emitter voltage of 50V, it can drive relays, LEDs, small motors, and other moderate loads directly from a m...
Transistor Array - NPN/PNP (IMD2AT108) - 5pcs
The IMD2AT108 is a complementary NPN/PNP transistor array IC that integrates two transistors, two base resistors, and two pull-up resistors into a single Mini6 package (similar to SOT-457). Commonly used for level translation and logic inversion in compact designs. Compatible with SOT-23 breakou...
Cool White LED Ring Light PCB - 70mm Diameter - 5V Power
This cool white LED ring light is a slim, bright PCB ring that makes it easy to add even lighting to costuming, photo/video projects, or any build that needs a clean ring of light. Just supply 5 V at up to 500 mA and it lights up immediately — no addressable LED library or microcontroller require...
Simple Water Detection Sensor with Digital Output
A simple, palm-sized water detection sensor that outputs a digital high signal when water or condensation is detected on its surface. The compact red PCB features interlocking traces connected to a lightly biased transistor — when water bridges two traces, the transistor switches on and the outpu...
IR Break Beam Sensor - 5mm LEDs
Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR,...
SMD LED - RGB WS2812B (Whole Reel)
The WS2812B (or "NeoPixel") may look like a common 5050-sized (5x5mm) SMD LED, but there’s actually an integrated control circuit embedded inside there too. Sometimes you don't need 10 or even 50, maybe you need a whole reel of 1000! If you are the person who needs that many than this is the perf...
TIP122G NPN Darlington Transistor - 100V 5A
·
The TIP122G is a high-power NPN Darlington transistor for switching heavier loads from a low-current microcontroller output. It is well suited to projects where an Arduino, Raspberry Pi or similar controller needs to drive a motor, solenoid, high-power LED strip or relay.A Darlington transistor c...
Transistor (pack of 5) - PNP
Transistor are a type of electronic switch used for controlling the flow of a circuit and amplifying signals.They have three legs: the base, the collector, and the emitter.NPN: When a voltage is applied to the base leg of the transistor it allows current to flow from the collector to the emitter....
Flexible LED Filament 3V - Green 130mm
A flexible green LED filament strip that bends and shapes easily for creative lighting effects. Operating at just 3 V and 20 mA, it's simple to power from batteries or low-voltage supplies. The 360° beam angle provides even illumination from all sides. Specifications Colour: Green Length: 130...
Gravity:DIGITAL IR Transmitter Module
An infrared transmitter is simply a Light Emitting Diode which generates IR light (invisible IR light)--light with a wavelength of between 1 mm and 750 nanometers, and some associated circuitry. In an infrared remote control, for example, pushing a button sends an electric signal to the LE...
