Have you ever seen a radial power resistors SQP?
High power ceramic resistors are widely used due to their core advantages such as high temperature resistance, strong stability, and moisture resistance, especially in the industrial, power, and electronic equipment fields. So, what are radial power resistors made of to achieve such outstanding performance?
Radial power resistors are manufactured by winding a metal alloy resistance wire around a ceramic rod, placing the assembly into a fire-resistant ceramic casing, and then encapsulating it with non-flammable, heat-resistant cement.
The rated powers of the resistors are as follows: 2W, 3W, 5W, 7W, 10W, 3WS, 5WS, 7WS, 10WS.
Taking the high-power ceramic resistor in the figure as a reference:
Series Number: SQM
It is 5W, 3Kohm.
Value Range ±5% (Ceramic Core): 0.1Ω - 180Ω
Value Range ±5% (Metal Oxide Film): 180Ω -100KΩ
Operating Temp. Range: -55℃ ~ +155℃
Temp. Coefficient (PPM): ±300ppm/℃

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.

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.
