Zero-Ohm Resistors: Uses and Benefits | Enrgtech Blog

 Zero-ohm resistors

A Zero-ohm resistor is simply a resistor with zero ohms. It’s a through-hole resistor that has been manufactured to have zero ohm of resistance and is marked with a single black band.  A surface-mount ceramic resistor has single or multiple numbers of zeros to represent the zero-ohm resistance. It is pretty much like a jumper wire that is shaped like a resistor. Why do you need a zero-ohm resistor? Why not just use a jumper?




Uses of a Zero-ohm resistor.

An alternative for jumper wire

The use of jumpers in circuits is common. They allow for unmatched flexibility. However, they are only applicable if you are going to solder manually. That is not the case in mass production. Mass production involves pick-and-place machines which do not have the ability to handle jumper wires. An extra machine would be required for that making the cost of production to rise. To avoid that, a zero-ohm resistor is used. It saves both cost and assembly time.

Mid-Power LEDs: Less Expensive for LED Lights

Image
  Mid-power LEDs Do you see that sleek, ultra-thin HD TV set in front of you? Well, its existence has been made possible by mid-power LEDs. Which can be  powered the shift from old cold CRT backlight TV. These are tiny LEDs measuring a few millimeters square. Courtesy of their size and weight, hundreds of them can be fitted unto a single light source but still weigh less than 250 grams. They can be pa packaged densely compared to high-power white LEDs. They offer relatively high-power white LEDs and a more uniform appearance. They also consume less power. Mid-power is for many reasons touted as the best alternative for LED lighting. High-power, mid-power, and low power LEDs To get a better grasp on mid-power LEDs is important to understand the three classifications of LEDs Low power They were the earliest LEDs in the market and were mostly used for indicator lights and identifying the status of machine condition. High power They are costly thus were initially used for research. Comme

An Introduction to Brushless Direct Current (BLDC) Motors

Image
The growing popularity Has your phone vibrated today? Well then, you just experienced a  brushless DC (BLDC) motor  in action.  BLDC motors  are synchronous motors that are powered by direct current through a drive module or controller. BLDC motors have witnessed rapid growth in popularity owing to their construction that makes them superior to the brushed counterparts. BLDC motor construction Rotor The rotor is made up of permanent magnets and its number of poles (North and South poles) varies from two to eight pairs. The permanent magnets are made from ferrite magnets. However, permanent magnets made from rare earth alloys are increasingly becoming popular owing to the advancement in technology. Rare earth alloys offer more magnetic density per volume while enabling the rotor to compress further for the same amount of torque. Such alloys also improve the size to weight ratio. There are two rotor designs for BLDC motors; the inner rotor and the outer rotor design. I

Little Know more about Brush-less Motors

Image
Brushless motors Brushless differs from conventional dc motors in the sense that it does not have brushes. Commutation is done using electronic drives to feed power to the stator windings. They consist of a rotor which is in the form of a permanent magnet and a stator that is in the form of polyphase armature windings. A  brushless DC motor  can be constructed in two ways; one is by placing the rotor outside the core and the other is by placing the rotor inside the core. How a brushless motor works Brushless motors are driven by electronic drives that  switch  the supply voltage between the stator windings while the rotor turns. There is a transducer that monitors the position of the rotor as it turns and conveys the information to an electronic controller. The controller then decides which stator winding to be energized based on the position of the rotor. Electronic drives are made up of two transistors each phase which is run by a microprocessor. The magnetic field i
