Can a resistor be used as a fuse
WebDec 6, 2024 · I replaced the 68 ohm fusible resistor (0.25w) with a 47 ohm (0.5w) one. I did some tests on the 22 ohm and 47 ohm resistors using my power supply. The 22 ohm one fused at 0.6 amps. The 47 ohm resistor (in series with the 22 ohm one) fused at approx 0.37 Amps (the 22 ohm survived but got a bit charred). WebDec 10, 2024 · A fusible resistor used as the main overcurrent component in a power supply or charger (as shown in Figure 2) can have a resistance of 10 Ω. A fuse, in contrast, has a resistance in the milliohms to 100s of milliohms range. Designers can use a fuse and an NTC thermistor to obtain equivalent overcurrent protection and inrush current …

Examples of widely used fuses for …
WebFuses are designed to safely protect other components in the circuit, but can require an additional level of protection in hazardous environments. The following are some justifications for fuse 40 mA - 80 mA: Transmitters, switches, solenoids, proximity encapsulation: • When a fuse opens a circuit, arcing occurs within the fuse. WebA fuse will pass current until the current is increased to a level that will cause the fuse to “open” the circuit, that the fuse will then no longer pass any current. A resistor will …
WebBy combining the features of a resistor and a fuse, circuit board space, volume, and weight can be saved. This means reduced complexity, greater reliability, lower manufacturing …
WebJun 2, 2024 · 2. AUTOMOTIVE FUSES. These fuses are specifically designed for automotive systems that run up to 32V and occasionally 42V. They come in ‘blade’ form (a transparent plastic envelope with flat contacts) and are colour coded according to rated current. Some of these types are also used in other high-power circuits. 3. china hut on clarkWebMar 26, 2016 · Electronics For Dummies. Resistors are among the most popular electronic components around because they're simple yet versatile. One of the most common uses of a resistor is to limit the amount of current in part of a circuit.
