Fusible Resistor Construction

In this fusible resistor the current flowing through the resistor first flows through a spring loaded connection that is positioned close to the body of the resistor. Using a fusible resistor sounded a rifht option for me since it will not only break during overload but will also limit the current in case of normal operation.

After a lot of googling found that the fusible resistor was the best fit for the protection design.

Fusible resistor construction. In construction partly because of the higher resistance usually required a resistor may have a much longer thinner wire than a fuse wound around the outside of an insulating tube and protected with an insulating coating. The dynamic braking resistor absorbs this energy and converts it to heat. It will typically use the same resistor film alloy and materials as a basis for a fusible part fig.

Name there is no need to enter special characters like commas or apostrophes. Fusible resistor fusible resistors are made of a partially organic film. If current and heat through the resistor gets high enough the solder will melt and the spring will pop up and open the circuit.

Rcd components inc resistor manufacturers electronic delay lines inductor hybrids surface mount carbon composition coils. If i use a fuse then i would have to use around 60 fuses since i have so many branches. The gain is that it does not needs a fuse holder and so it has one very small size.

Sometimes they can look very similar. No field is mandatory. To make a fusible resistor the manufacturer attaches a small spring to one end of the resistor.

A small amount of solder will hold this spring in place. Fusible film resistor technology starts with a standard film resistor design. A license search will list qps officers former names andor dbas if any.

The heat generated by the wirewound resistor under normal conditions would not be sufficient to melt the blob of solder holding a spring wire in place. The flow of high current melts the film opening the circuit and stopping the flow of current through the resistor. License enter a 6 digit license number.

For a reliable and repeatable fusing characteristic the sputtered film thickness and composition must be more carefully monitored to ensure uniformity across the manufacturing lot.
