In product selection, the choice of surge resistance and power boosting resistance should be based on the core contradiction of the application scenario, rather than simply comparing parameter specifications. Both are designed for transient energy shock and steady-state power overload, and the selection logic needs to be comprehensively evaluated from three dimensions: demand essence, cost-effectiveness, and system reliability. The specific decision-making framework is as follows:
Anti surge resistors have higher costs compared to ordinary thick film resistors, and their price differences are mainly determined by material upgrades, process complexity, testing and certification costs, and market demand characteristics. The specific reasons are as follows:
The design of anti surge resistors is not just about simply improving the steady-state power of ordinary thick film surface mount resistors, but also involves multidimensional optimization for transient energy impact characteristics. The core differences between the two are reflected in design objectives, material properties, and structural reinforcement, which can be analyzed from the following perspectives:
Surface mount resistors require anti surge treatment, which is closely related to their physical characteristics, application scenarios, and circuit reliability requirements. The specific reasons can be analyzed from the following three aspects:
Anti surge patch resistor is a key protective component widely used in scenarios that require resistance to transient voltage surges. The following are the main brand manufacturers, their technical characteristics, and application areas compiled from comprehensive search results:
Under the premise of the same parameters, surge resistance can theoretically replace ordinary thick film resistors, but it needs to be comprehensively judged based on specific application scenarios. The following is a technical analysis:
SUSUMU, Rohm, Vishay, and others are known for their metal film technology, while Tian'er, Guangjie, and others cover both thick film and metal film products. When selecting, it is necessary to match specific requirements (such as power, packaging, accuracy) and application scenarios (such as automotive electronics, medical equipment). For more detailed information, please refer to the official websites of each brand or contact agents (such as Shunhai Technology, Jiebixin Technology).
In medical products, choosing TGL251220FR200E04Z metal film resistors from Tian'er Company instead of pure metal alloy resistors is mainly based on its comprehensive advantages in surge resistance, stability, safety standards, and other aspects. The following analysis will focus on the demand for medical equipment, comparison of resistance characteristics, and specific application scenarios:
