MF 0.1% High Precision Metal Film Resistors are a widely used type of resistor. Literally speaking, they are metal resistors with leads at both ends. Have you ever carefully observed the color bands on them? What do they mean?  How to identify the colors of 5-band metal film resistors?

Let WEET guide you to distinguish these colorful bands!

Introduction

First of all, the color band marking of 5-Band Metal Film Resistors contains three types of information: significant figures, multiplier, and tolerance. Different colors on the resistor represent different values.  Next, I will list the corresponding values of each color one by one: Black = 0; Brown = 1; Red = 2; Orange = 3; Yellow = 4; Green = 5; Blue = 6; Purple = 7; Gray = 8; White = 9

• 1st band = First significant figure

• 2nd band = Second significant figure

• 3rd band = Third significant figure

• 4th band = Multiplier

• 5th band = Tolerance

Take the MF 5-Band Metal Film Resistors in the figure as an example, with color bands of red, black, black, black, brown:

• Significant figures: Red = 2, Black = 0, Black = 0

• Multiplier: Black = 10⁰ = 1

• Tolerance: Brown = ±1%

• Calculation result: 200 × 10⁰ = 200Ω (with a tolerance of ±1%)

After such an explanation from WEET, isn't it easy to identify the colors of 5-Band Metal Film Resistors?

Ceramic composition resistor widely used in industrial control, power supply equipment, automotive electronics, instrumentation and other scenarios, how much do you actually know about SQP Ceramic Resistor 5 watts?

Flameproof ceramic resistor is manufactured by winding metal alloy resistance wire around a ceramic rod, which is then placed in a refractory ceramic case and encapsulated with non-flammable cement.

Advantages of ceramic composition resistor: 

• Excellent heat resistance

• Ability to withstand short-term overloads

• Low noise

• Superior explosion-proof performance

• Reliable protection capability

Working principle of ceramic resistors:

The core operation of ceramic resistors 1W/2W/3W/7W/10W is based on the Joule heating effect of electric current and the resistive properties of ceramic materials. Through the synergistic effect of the ceramic substrate and conductive medium, they achieve current limiting, energy dissipation, and signal regulation.

Refer to the ceramic resistor shown in the figure below.

SQP 5Watts ceramic resistor Ohm Range:

• Wire Wound: 0.1Ω- 47Ω

Film Rod High Power Resistors are widely used in large quantities, and their price has attracted much attention. Do you know what is the price of WEET MOF 2W resistive ceramic rods?

INTRODUCTION

In fact, the price cannot be directly defined as it is affected by numerous factors.

The price of resistive ceramic rods is closely related to multiple aspects such as raw material quality, product specifications, and production processes. Meanwhile, changes in procurement models and market environments can also cause fluctuations in their prices.

• Product Specifications and Parameters: This is a key factor affecting the price, mainly including two aspects: power and resistance value.

• Raw Material Quality: The quality and price of its core constituent materials directly determine the cost. Additionally, if the metal resistance wire in the rod has high purity and good high-temperature resistance, the material cost will increase, ultimately leading to a higher product price.

• Production Process Level: Ordinary resistive ceramic rods are produced using mature standard processes, featuring high efficiency, low cost, and affordable prices. In contrast, high-temperature resistive ceramic rods require special processes to enhance their high-temperature resistance and stability.

• Market Supply and Demand & Industry Environment: When industries such as electric vehicles and smart homes develop rapidly, the market demand for resistive ceramic rods surges. If the supply fails to keep up with the demand, the price will rise.

• Procurement Quantity: For bulk purchases, suppliers will offer price discounts. Generally, the larger the procurement quantity, the lower the unit price.

SUMMARY

The above are the factors influencing the price of resistive ceramic rods. For inquiries about the price, welcome to contact WEET, and we will tailor the most favorable ordering plan for you.

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/℃
