What Is The Price Of WEET MOF 2W Resistive Ceramic Rods?

In Ceramic Capacitors on by WEET

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.

In Audio Capacitors on by WEET

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.
