Those colorful resistors we see in daily life - you'd never guess they're the original form of resistive ceramic rods before being painted! So, what is MF resistive ceramic rod? What is its function?
A Rod Resistors With High Stability is an electronic component based on ceramic materials such as alumina and zirconia. Resistive ceramic rod is mainly used in circuits requiring high insulation and high temperature resistance, and is commonly found in industrial equipment, electronic devices, and other fields.
Resistive ceramic rod is classified into three types based on different materials:
Thick-film resistive ceramic rod: Manufactured using isostatic pressing technology, it is suitable for precision resistor applications.
Zirconia ceramic rod: Boasting superior high-temperature resistance, it is often used as an insulating structural part in high-temperature environments.
Alumina ceramic rod: Contains 95%～99% alumina, featuring excellent insulation performance. It is suitable for high-frequency circuits, inductor cores, etc.
What is Film Rod High Power Resistors function?
Industrial machinery: High-temperature components such as electric furnace tubes and silicon carbide rod protection tubes.

In devices such as frequency converters, automotive LED lights, and professional audio equipment, there lies a key "guardian" - the high power AH gold aluminum housed wire wound resistor.
So, what is wire wound resistor made of?
It features a stable framework of high-temperature resistant ceramic rod, wrapped with high-quality alloy wire as the resistance core. It is then precision-potted with high-insulation paste and paired with an aluminum alloy housing that combines heat dissipation and protection, ensuring stable performance and enhanced operational safety.
But what characteristics make it stand out?
High rated power and ultra-precision (accuracy up to ±1%).
Excellent stability with weather resistance and reliable performance. The aluminum alloy housing not only dissipates heat quickly but also isolates external dust and moisture.
Wide power range, offering 6 models (5 to 250 watts) to adapt to different power scenarios.
Resistance Tolerance: ±10%, ±5%, ±3%, ±2%, ±1%, ±0.5%.
Superior heat dissipation, operating temperature range from -55℃ to +275℃.
Taking the 50W wire wound resistor for TUBE AMP AUDIO in the following figure as a reference, its resistance range is 0.1ohm ~ 100Kohm.

What is the KNP audio amplifier resistor?
KNP resistor for audio amplifier also known as wire wound audio resistor. As the name suggests, an audio amplifier resistor is a resistor used for audio applications.
What role do wire wound resistor play?
KNP Wire wound resistor play roles such as noise suppression and circuit protection in audio circuits.
What is wire wound resistor made of?
It is made by winding resistance wire.
What about the resistor packages?
Bulk tape packaging and strip packaging.
Resistors are widely used, but different applications require different types of resistors. Do you know the differences between radial and axial resistors?
Let WEET tell you, the core difference between radial and axial resistors lies in their lead arrangement and application scenarios.
INTRODUCTION
Resistors Types
Through hole resistor: Leads extend from both ends of the resistor body along the central axis.
Radial resistor: Leads protrude from the same end (or adjacent positions) of the body.
Mounting Method and Space Occupation
Through hole resistor: Axial resistor sizes for through-hole mounting, requiring linear space reserved along the direction of the leads.
Radial resistors: Support through-hole mounting and surface mount technology (SMD). Vertical mounting saves horizontal space, enabling a more compact layout.
Application Scenarios
Through hole resistor: Commonly used in traditional circuits, audio equipment, and projects with fixed requirements for lead spacing.
Radial resistors: Preferred for miniaturized devices such as printed circuit boards (PCBs) and high-density circuits.

As one of the most basic components in electronic circuits, a resistor exerts a certain hindrance to the flow of electric current. But do you know how to read carbon film resistor color code?
These colorful bands actually indicate the resistor's resistance value - a detail that can be confusing for many beginners. However, with WEET guidance, you'll surely learn to identify the resistance value quickly.
First, carbon film resistor is generally classified into 4-band resistors and 5-band resistors based on the number of color bands.
Start by memorizing this mnemonic:
Brown=1, Red=2, Orange=3, Yellow=4, Green=5, Blue=6, Violet=7, Gray=8, White=9, Black=0.
Resistance value:
Gold=±5%, Silver=±10%.
Take the CF Series 4-band resistors in the figure below as an example:
1st digit: Yellow=4
2nd digit: Red=2
Multiplier: 2×100
Tolerance: ±5%
So, the resistance value of this resistor is 4K2 Ω.
After this explanation, you must have a general understanding. Feel free to contact WEET if you need carbon film resistor!

Do you know how to choose an axial leaded resistor that suits you?
Here are a few suggestions from WEET.
Resistance Value and Tolerance
Determine the required resistance value (typically ranging from a few ohms to several megaohms) based on the circuit design requirements. Choose an appropriate tolerance grade according to the precision needs.
Rated Power
Select the rated power based on the actual power consumption in the circuit. It is recommended to reserve a 20%~30% power margin to prevent overheating damage caused by the axial leaded resistor operating at full load for a long time.
Temperature Coefficient (TCR)
It indicates the degree to which the axial leaded resistor's resistance changes with temperature. For precision scenarios (such as medical equipment and test instruments), select low-TCR models (e.g., ±10ppm/℃ or lower). For general scenarios, the requirement can be relaxed to ±100ppm/℃.
Package Size
Choose a suitable body size based on the circuit board's spatial layout. Ensure the pin spacing matches the pad spacing of the circuit board to facilitate soldering and installation.
