In the selection of electronic components, resistance power often directly affects the reliability and volume of circuit design. Many engineers have found in practical applications that, under the same packaging size, the power of thin film resistors is often lower than that of thick film resistors. The principle behind this phenomenon can be traced back to the manufacturing processes and material properties of both.
In the field of electronic design, thick film resistors are one of the most widely used components, known for their low cost, high power, and complete specifications. But in precision circuit design, engineers often face a ceiling: why is the temperature drift (TCR) of the vast majority of ordinary thick film resistors on the market usually labeled as 100ppm/℃ or higher? Even thick film resistors with certain precision seem to have their temperature drift limit stuck around the threshold of 100ppm.
When engineers choose surface mount resistors, the first choice they often face is: thick film resistors or thin film resistors, which one should be used? Although there is only a one character difference, the manufacturing process, performance focus, and application scenarios of the two are vastly different. Many people mistakenly believe that "thick film" means large volume and "thin film" means small volume, but this understanding is not accurate.
In electronic circuit design, choosing resistors can sometimes be quite confusing, especially for critical positions such as current detection and sampling. Many people may ask: Are alloy resistors necessarily better than thick film resistors? Today we will talk about this topic.
This high-power thick film surface mount resistor produced by EVER OHMS (Tian'er Technology) is widely used in many power circuits and industrial control equipment due to its 2512 package size, 33K resistance, and 2W power configuration. This article will provide a detailed analysis of the parameter characteristics of this resistor, helping engineers better understand and select this component.

In electronic circuit design, a common problem often arises when selecting resistors with the same precision, packaging, and resistance: which is better, metal film or thick film? The answer is not simply 'yes' or' no ', but depends on your application scenario. If high precision, low temperature drift, and low noise are pursued, then the selection of metal film resistors will indeed tend towards metal films; But if cost is the primary consideration, thick film resistors have significant advantages.

To understand why silver prices can leverage the entire thick film resistor market, it is first necessary to understand the manufacturing process of thick film resistors. The core of thick film resistors is formed by attaching conductive paste (metal), glass glaze and other materials to ceramic substrates through screen printing and sintering processes.
Recently, the metal raw material market has not been calm, especially the continuous rise in silver prices, which has brought a chain reaction to the entire electronic manufacturing industry chain. For many procurement and engineers, the most direct feeling may be receiving a price increase letter from the supplier. In this cost driven industry adjustment, thick film surface mount resistors, as a widely used passive component, have been significantly impacted. This article will use simple and understandable language to discuss what the rise in silver prices means for thick film surface mount resistors, and how to ensure the stability of the supply chain in such a market environment.
