Resistors
Resistors are one of the most essential components in any electronics kit — from limiting current in LED circuits to building voltage dividers and filter networks. Our range covers through-hole and SMD types, carbon and metal film, in individual values or handy assortment packs.
Whether you're a student, hobbyist, or working on a professional project, you'll find the right resistance value and wattage rating here. Shipped from Australia, these are a reliable staple for Arduino builds, breadboard prototyping, and STEM education.
