Surface Mount Device (SMD) resistors, also called chip resistors, are among the most widely used passive components in modern electronic circuits. With the shift from through-hole technology (THT) to surface-mount technology (SMT), SMD resistors have become the industry standard for compact, high-density, and automated PCB assembly. This article presents an in-depth, technical explanation of SMD […]
A fusible resistor is a safety resistor designed to do two jobs at once: limit current and act like a fuse. Under normal conditions it behaves like a regular resistor, but if too much current flows, it overheats and safely opens the circuit, preventing damage or fire. You’ll often find fusible resistors in power supplies, […]
A wire wound resistor is a type of fixed resistor in which the resistive element is made by winding a metal alloy wire around an insulating core. Unlike carbon or film resistors, the resistance value in a wire wound resistor is determined primarily by the length, diameter, and material of the wire used. Wire wound […]
A metal oxide resistor is a type of fixed resistor that uses a metal oxide film, most commonly tin oxide (SnOâ‚‚), as its resistive element, deposited on a ceramic substrate. Designers widely use these resistors in electronic circuits that require high temperature stability, high voltage endurance, and strong surge resistance. Metal oxide resistors were developed […]
A thick film resistor is one of the most widely used fixed resistors in modern electronic circuits. It is manufactured by depositing a resistive paste (thick film) onto a ceramic substrate and then firing it at high temperature to form a stable resistive layer. Due to its low cost, mechanical robustness, and compatibility with mass […]
A metal film resistor is a precision fixed resistor widely used in electronic circuits where high accuracy, stability, and low noise are required. Compared to carbon composition and carbon film resistors, metal film resistors offer tighter tolerance, lower temperature coefficient, and superior long-term reliability. They are extensively used in analog circuits, instrumentation, audio equipment, medical […]
