14 best electronic inductors
Electronic inductors, also known simply as inductors, are passive electronic components commonly used in electrical circuits and systems. They are essential elements in many engineering applications, including transportation systems. Here's some information about electronic inductors and their relevance to engineering, including transportation:
Basic Principle: An inductor is a two-terminal passive component that stores electrical energy in a magnetic field when current flows through it. It opposes changes in current by inducing a voltage proportional to the rate of change of current passing through it, following the equation V = L * dI/dt, where V is voltage, L is inductance, and dI/dt is the rate of change of current.
Construction: Inductors are typically made by coiling wire (usually copper) around a magnetic core. The inductance value depends on factors such as the number of turns in the coil, the cross-sectional area of the coil, and the magnetic properties of the core material.
Inductance Value: Inductors are rated by their inductance value, which is measured in henrys (H). Common units include microhenrys (μH) and millihenrys (mH).The inductance value determines how effectively the inductor resists changes in current.
Applications in Engineering:
- Transportation Systems: Inductors are used in various transportation systems, including railways and automotive applications. They can be found in components like traction inverters, power converters, and electric motors, where they help manage and control electrical currents and voltages.
- Power Electronics: In engineering, inductors are vital components in power electronics circuits. They are used in converters, inverters, and regulators to filter and control electrical energy, reducing harmonics and ensuring stable power supply.
- RF Circuits: Inductors are used in radio frequency (RF) circuits, such as those found in communication systems and radar equipment, to filter signals and tune circuits.
- Switching Regulators: Inductors are a key component in switching regulators used for voltage conversion and regulation in power supplies.
- Signal Processing: They are also used in signal processing circuits, such as in audio equipment, to filter out unwanted frequencies.
Types of Inductors:
- Air-Core Inductors: These have a non-magnetic core and are often used in high-frequency applications.
- Ferrite-Core Inductors: These inductors use a core made of ferrite material, which enhances their inductance and is commonly used in electronic applications.
- Toroidal Inductors: These are inductors wound around a donut-shaped core, offering compact and efficient performance.
Size and Form Factor: Inductors come in various sizes and shapes, depending on the application. Surface-mount inductors are commonly used in modern electronics due to their small size and compatibility with printed circuit boards (PCBs).
Engineering Books: Engineers and students studying electrical and electronic engineering can find comprehensive information about electronic inductors in textbooks and reference materials on topics like circuit theory, electromagnetics, and electronics.
Electronic inductors play a critical role in engineering applications, including transportation systems, by managing electrical energy, ensuring efficient power conversion, and controlling electromagnetic interference. Their usage is widespread in various industries to create and control electrical and electronic circuits and systems.

User questions & answers
| Question: | Does each part have a label of what value it is |
| Answer: | There is no included label or datasheet. Parts contain no identifying markings. |
| Question: | What are the component values? There are no markings on the inductors or the case the came in |
| Answer: | I checked them and the values listed are in the order they are in the box from top left to bottom right. So top row was : 10µH, 100µH, 220µH, 10µH Second row was: 1µH, 4.7µH, 15µH, 1mH/1kµH Third row was: 33µH, 150µH, 1mH/1kµH, 10mH/10kµH The third row is out of order on mine, so be sure to check the values of the parts before you use them (which is always a good practice anyway). |

User questions & answers
| Question: | What is the maximum current rating (not wattage) and who is the manufacturer |
| Answer: | Cofufu is the manufacturer. For the 330 uH I got 311 uH ESR 5.4 Ohm at 100Hz 303 uH ESR 5.4 Ohm 120 Hz 311 uH ESR 5.5 Ohm at 1kHz 290 uH ESR 6.62 Ohm at 10 kHz and 271 uH ESR 8.85 Ohm at 100kHz so depending on the frequency it goes from .25 W = I^2 * R -> .25/5.4 = I^2 = 4.629E-2 I = .215 A at 100Hz to .168 A at 100kHz. For the 1mH .127 A - .090 A for the 1 uH 1.29 A for all freq. So I guess as you go from lower to higher inductance you are able to use less current by a factor of ten. Hope that helps. Of course the inductive reactance doesn't actually dissipate any current as heat, just the equiv series resistance which appears to be a function of the inductance and a little bit of frequency |
| Question: | Are these micro h or mill h? i just received a batch an everything is marked wrong wat i received was mh not uh |
| Answer: | 1 mH = 1000 uH. The batch I received were all correct. I think it's just an issue of not printing the "micro" prefix correctly, so they used an m for whatever reason. Also, needless to say, if they were indeed millihenries, they would be much larger :-) I can't speak to your particular batch, but mine were all correct even though they were confusingly marked. |
| Question: | The title says "22 value total 220pcs", the picture says "28 value total 280pcs". Which one is correct |
| Answer: | Now 28 value total 280pcs |
| Question: | what is the tolerance |
| Answer: | 10% |

User questions & answers
| Question: | What is the power rating |
| Answer: | 1/4W |
| Question: | Are they in properly labeled bags |
| Answer: | These are broken out into 3-4 bags containing a range of inductors. 1 Bag might contain 1uH to 20uH, the next 20uH to 82uH, etc. Inside the bags, they are bound together on paper tape, so you'll have all the same value inductors together, but you'll need to test them, or check the bands. I'd recommend testing as I've had several that were 20% off. |
