Since its establishment in 1988, Ever Ohms Technology has focused on the research and manufacturing of electronic components. The metal film resistor series adopts vacuum evaporation or sputtering technology to deposit metal thin films such as nickel chromium alloy on ceramic substrates, which has the characteristics of strong stability, low temperature coefficient, low noise, and good high-frequency characteristics.
In the current sampling circuit of the BMS system for new energy vehicles, a Ever Ohms metal film resistor is ensuring long-term accuracy of battery status monitoring with an annual drift rate of less than ± 0.5%.
The TRL0805X2F1R00P05Z model produced by Ever Ohms Company is a metal film surface mount resistor that performs well in many fields. It precisely balances size, power, and performance, and its core parameter combination of 0805 1R 0.25W makes it an ideal choice for current detection, current limiting, and voltage divider applications in many circuit designs.
Can metal film resistors replace thick film resistors? The answer to this question is not simply 'yes' or' no ', but depends on the specific application scenario and performance requirements. Understanding the difference between these two resistors is the key to achieving successful replacement.
The following is a summary of recommended models for 0402 packaged 4.7 Ω resistors (classified by characteristics,):
Based on the model list you provided, the following is a detailed introduction to these 0402 packages and 10 ohm (10R) surface mount resistors:
Based on your list of metal film surface mount resistor models with 1206 package, 3.6 Ω resistance, 1W power, and ± 1% accuracy, combined with their core characteristics, application scenarios, and market supply situation, the following is a selection analysis and recommendation:
Seeing that you are selecting resistors for 1206 size, 2.2 Ω, 1% accuracy, and 1W power, let me help you analyze the differences and applicable scenarios of these models. These models come from different series of the two major manufacturers, Tian'er and Ellon, with the same core parameters but different emphasis on their characteristics:
When selecting metal film resistors and alloy resistors with the same parameters (such as resistance, power, tolerance, etc.), the key is to understand the different performance focuses caused by their material characteristics and structural differences, and then decide according to specific application requirements. There is no absolute 'better', only 'more suitable'.
Metal film resistors play a key role in many fields that require high performance of electronic components due to their advantages of high accuracy, low temperature coefficient, good stability, and low noise. Its main application areas include:
