EMA25F3W0R082MDG is a 2512 encapsulated alloy resistor produced by ENOMOTO company. The following is a detailed description of it:
The following is a detailed technical description of the SP2512FR082E3WPKH Xinwei alloy resistor, compiled based on its parameter characteristics, application scenarios, and manufacturer background information:
Based on your requirements (2512 package, 0.082 Ω/82m Ω resistance, 3W power alloy resistor), I have compiled the following brand models and purchasing channel information. Although the search results do not directly list models with resistance values that completely match 0.082 Ω, the alloy resistor series of the following brands cover a similar resistance range (such as 0.5m Ω -100m Ω), and support 2512 package and 3W power, which can be customized or selected to meet the needs.
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'.
Surface mount alloy resistors are widely used in fields such as current detection, power conversion, automotive electronics, and industrial control due to their low temperature coefficient (TCR), high power density, excellent pulse resistance, and stability. Its mainstream packaging follows the electronic industry's common surface mount component size standard (EIA/JEDEC). The following is an original summary of mainstream packaging for surface mount alloy resistors, arranged in ascending order of size:
As the core component of current detection and power management, alloy resistors will be deeply bound to the three main lines of new energy revolution, intelligent upgrading, and material science breakthroughs in their future application trends. From new energy vehicles to 6G communication, from Industry 4.0 to medical electronics, the technological evolution and scenario expansion of alloy resistors will present the following six trends:
The following is a comprehensive analysis of the future development trend of alloy resistors, combined with industry trends, technological innovation, and market data, to sort out its evolution path from multiple dimensions:
As the core component of current detection and power management, the packaging form of alloy resistors directly determines the adaptability of application scenarios. From consumer electronics to new energy vehicles, from precision instruments to industrial equipment, the packaging form of alloy resistors has undergone technological evolution from plug-in to surface mount, and from two-dimensional to three-dimensional. The following is a systematic review of the main packaging forms of alloy resistors:
The material selection of alloy resistors directly affects their resistance characteristics, temperature stability, anti-interference ability, and applicable scenarios. According to the differences in alloy composition and performance, mainstream materials can be divided into the following seven categories, each with unique physical properties and application focus:
Core principle: Measure the resistance value to ensure it is within its nominal value and allowable tolerance range, while observing its physical state and functional performance in the circuit.
