13 best fixed resistors
Fixed resistors are fundamental electronic components widely used in electrical circuits to control the flow of electric current. They are passive components, meaning they do not produce energy but instead resist the flow of electric current passing through them. Fixed resistors have a constant resistance value that cannot be adjusted or varied, unlike variable resistors which can change their resistance value manually or automatically. Here are some key points about fixed resistors:
1. Function:
Fixed resistors limit the current flow and voltage levels in a circuit. They are used for various purposes such as voltage division, current limiting, biasing transistors, and setting the operating point of electronic devices.
2. Construction:
Fixed resistors are typically made of materials with high resistivity, such as carbon composition, metal film, metal oxide, or wire wound around an insulating core. The choice of material depends on factors like precision, stability, and power handling capacity required for the specific application.
3.Types of Fixed Resistors:
a. Carbon Composition Resistors:
- Made of a mixture of carbon particles and insulating ceramic.
- Suitable for general-purpose applications and low-frequency circuits.
b. Metal Film Resistors:
- Made by depositing a thin metal film onto a ceramic substrate.
- Offer higher precision and stability compared to carbon composition resistors.
- Commonly used in audio and precision electronic circuits.
c. Metal Oxide Resistors:
- Made using a metal oxide film deposited on a ceramic rod.
- Provide high stability, tolerance, and power handling capabilities.
- Suitable for high-power applications.
d. Wirewound Resistors:
- Constructed by winding a resistive wire around a ceramic or fiberglass core.
- Can handle high power levels and have excellent stability.
- Commonly used in power electronics and industrial applications.
4. Identification:
Fixed resistors are color-coded or labeled with numerical codes to indicate their resistance value, tolerance, and sometimes power rating. The color code system uses different colored bands to represent numbers, multipliers, and tolerance values.
5. Applications:
Fixed resistors find applications in various fields, including electronics, telecommunications, automotive, aerospace, and industrial automation. They are essential components in electronic circuits, ensuring proper operation and preventing damage to sensitive components.
6. Considerations:
When selecting a fixed resistor for a specific application, factors like resistance value, tolerance, power rating, and temperature coefficient must be considered to ensure the resistor can handle the conditions it will be subjected to in the circuit.
In summary, fixed resistors are crucial passive components used in a wide range of electronic applications to control current flow and voltage levels. Their stable and unchanging resistance values make them valuable components in designing reliable and efficient electronic circuits.

User questions & answers
Question: | What is the voltage rating of Bojack 1/2 watt resistors |
Answer: | Depends on the resistance value, limited by the power rating of 0.5W. Power according to Ohm's law: P=U^2/R = 0.5W max So, the maximum voltage is SQRT(0.5*R) For the lowest resistor value (1Ω), the maximum voltage is SQRT(0.5*1) = 0.707V. For the highest value (1MΩ) the theoretical maximum voltage is SQRT(0.5*1000000) = 707V, which is quite dangerous! For these voltages you would need special resistors that are designed for high voltage applications. I would not go over 200V with a metal film resistor. |
Question: | Can I use this with a 12 V adapter |
Answer: | It should be possible, mainly referring to the current of the components. Thank you |

User questions & answers
Question: | Are these the best ohm values to use on led lights that require between 5-12 volts? I intend on using a 9v battery to run these..,individually |
Answer: | Yes, I think you can get by with the 470 ohm resistors. They get a little warm to the touch when using a 9 volt battery. They are drawing about 15.5 ma using the 470 ohm resistors. I usually set mine to near 20 ma so, I usually use the 1/2 watt resistors for a safety factor. The power drawn is about 113 mw so this should work for you, that is at 9 volts. |
Question: | What is the length of these resistors (body) minus leads |
Answer: | 1/4 Watt Resistor Size: Total length: 60mm Body length: 6mm One side lead length: 27mm Maximum body diameter: 2.6mm Minimum body diameter: 2.0mm Lead diameter: 0.35mm |
Question: | Do these lower the voltage by 3 volts or what should i be looking for? i need to drop 6 volts to power a tamiya motor |
Answer: | You need to state what the rated current is for the motor, and the nominal voltage of your power supply. I am not familiar with the motor you are using, but assuming it is a DC motor and for illustration we shall pretend it draws 30 milliamps at 3 volts, and that your power supply is rated at 6 volts DC, we can now calculate the resistance needed to dop the voltage for the motor. To drop 3 volts across a resistor at 30 milliamps you would use the basic fomula V = IR where V is the voltage, I is the current, and R is the resistance. To get R we divide V by I. 3 Volts divided by 30 milliamps give a resistance of 100 Ohms. It is for you to work out your required resistance value from here. Also, you need to consider your wattage for the resistor - wattage is the power being dissipated by the resistor. P = VI where P = power (watts), V = voltage and I = current. for my example, 3 Volts * 30 milliamps = 0,09 watts - a 0.25 watt resistor will be fine. If you were dropping 3 volts across a esistor and your current was 0.3 milliamps, your 0.25 watt resistor would glow cherry red and then likely stat to burn - you need to consider the power rating of the resistor as well as the resistance value. |

User questions & answers
Question: | will this fit am |
Answer: | This will fit any processor or more importantly the motherboard. It comes with a couple plastick guides they are slotted to slide wherever they need to be put. But they only go corner to corner. I would suggest replacing the plastic with aluminum rod from a hobby shop. |
Question: | does it come with 2 blocks or just |
Answer: | one block (+ two cute charms) When i ordered it i could have sworn it came with two. But looking now the only indication of that was the plural use of blocks in the "This Item: SZZY Aluminum water cooling blocks for cpu Heatsink Cooler plater 41x 41 x 12mm". |
Question: | How many blocks and 12v 60w peltier chips would one need to cool 8.33 US gallons of nutrient at a chilled temp of 65-68 F |
Answer: | Peltier plates work off of temperature differential. Around room temp, you wouldn't need much energy but it also depends on the size of your plate, the amps, temperature control, insulation, the speed of moving water through your pump, on and on and on... That's engineering. |
Question: | can this be used on a 780 GPU |
Answer: | There is no mounting kit and hard to find one. Bard fitting OD is not 3/8 so does not fit (loose) most 1/2 OD tubes. I use 40mm fans to cold down chip sets. |
