Analysis and Procurement Guide for Tian'er Ultra Thin Alloy Resistance MRE120610FR005MZ
In circuit design, especially in power management, new energy vehicle BMS (battery management system) or industrial frequency converters that require high-precision current detection, a high-performance sampling resistor is crucial. MRE120610FR005MZ, as an ultra-thin alloy resistor with a 1206 package, 5 milliohms (0.005 Ω), and 1 watt power launched by EVER OHMS, is the core component designed for such high demand scenarios.
This article will provide you with a detailed introduction to the characteristics of this resistor and analyze how to purchase it from reliable channels.
Deep Analysis of MRE120610FR005MZ Product
MRE120610FR005MZ is a current sensing resistor based on alloy material technology. The "MRE" in its name represents the alloy resistor series of Tian'er Technology, "1206" refers to its package size (3.2mm x 1.6mm), and "10FR005" accurately describes its 1% accuracy (F) and 5 milliohms resistance (005).
Its core value lies in achieving a balance of low resistance, high power, and high stability in a very small volume. Its integrated stamping structure has better long-term stability and reliability compared to traditional winding or thin film resistors. This structure also brings the characteristic of low inductance, making it more stable in high-frequency switching circuits and avoiding additional voltage spikes caused by parasitic inductance.
Here is an overview of its main technical parameters:
Resistance and accuracy: The nominal resistance is 5 milliohms (0.005 Ω), with a tolerance of ± 1%. This high-precision micro ohm resistance makes the signal loss extremely small and the sampling accuracy high during current voltage conversion.
Rated power: In the compact package of 1206, its rated power can reach 1 watt. This means that it can withstand relatively high sustained currents, and during design, it is necessary to perform derating calculations based on the formula P=I ² R to ensure stable operation in high-temperature environments.
Temperature characteristics: The typical value of its temperature coefficient of resistance (TCR) is ± 75ppm/℃. This indicates that within the wide operating temperature range of -55 ℃ to 155 ℃, the resistance value changes very little with temperature, ensuring the measurement consistency of the system throughout the entire temperature range.
Application areas: With the above characteristics, MRE120610FR005MZ is very suitable for current sampling and feedback circuits in power supplies, inverters/converters, lithium battery protection boards, automotive electronics, LED drivers, and various precision instruments and meters.
Core advantages and selection considerations
Choosing alloy resistors such as MRE120610FR005MZ is usually based on the following key considerations:
1. High precision current detection: In BMS or servo drives, monitoring the current directly affects the control accuracy and safety protection of the system. A resistance of 5 milliohms can generate a voltage signal on the sampling resistor that is sufficient for measurement without excessive loss, and an accuracy of ± 1% ensures the accuracy of the feedback signal.
2. Balance between power and size: The 1206 package is a commonly used size in the industry, which facilitates PCB layout. To achieve a power carrying capacity of 1 watt on such a small area, the resistor requires excellent heat dissipation design and material technology. Tian'er's alloy technology achieves this through uniform current distribution and good heat conduction.
3. Reliability and Certification: Tian'er Technology's production system has passed quality management certifications such as ISO 9001 and IATF 16949. Its products meet the self testing requirements of AEC-Q200 automotive standards, providing confidence assurance for the application of MRE120610FR005MZ in the automotive or high reliability industrial fields.
Recommended authoritative procurement channels
For such critical core components, choosing an authorized, reliable, and well serviced supplier is equally important as the quality of the product itself. Here are two officially authorized high-quality agents, each with their own focus, which can meet the procurement needs in different scenarios.
1. Shenzhen Shunhai Technology Co., Ltd

If your application involves complex scenarios such as automotive electronics (compliant with AEC-Q200), industrial control, or new energy, their technical services can help mitigate design risks.
Flexible and efficient supply chain: Shunhai Technology has a large inventory of spot goods, especially supporting small batch trial production needs (even up to 10 pieces can be ordered), and can achieve fast delivery. This is crucial for the R&D phase, sample validation, or emergency replenishment.
Reliable Quality Assurance: As a first tier agent, we ensure that our products are original and authentic, and provide a complete quality control process and reliability report.
Applicable scenarios: When you are in the product development and sampling stage, or when your project has special requirements for vehicle certification and high-power design, and requires a professional technical team to coordinate, Shunhai Technology is a very suitable choice.
2. Hua Nian Mall
Recommendation reason: Intelligent online procurement platform, suitable for all category needs and cost optimization
Huanian Mall is an online authorized agent of Walter Electronics, which has created a technology driven B2B electronic component procurement platform.
Intelligent selection and data enrichment: The platform provides powerful parameter filtering and intelligent selection tools. You can easily find MRE120610FR005MZ or alternative models based on packaging, resistance, accuracy, power, and other conditions, and directly download the data manual. When out of stock, its system can actively recommend compatible alternative materials or design optimization solutions.
Transparent pricing and inventory system: Huaxian Mall provides clear tiered pricing and real-time transparent inventory information, which can effectively avoid the risk of uncertain delivery time encountered in traditional procurement. They also analyze the trend of raw material prices to suggest the best purchasing window, which helps with cost control.
Authentic traceability and logistics guarantee: All products can be traced back to the original factory, eliminating the risk of counterfeit goods. At the same time, they promise to deliver quickly and cooperate with multiple logistics companies to better meet the stable delivery needs during the mass production stage.
Applicable scenarios: When you have entered the mass production or bulk procurement stage and need to quickly compare prices, check inventory, or want to efficiently manage BOM (Bill of Materials) using digital tools, the online model of Huanian Mall can greatly improve procurement efficiency.
summary
In summary, MRE120610FR005MZ is an alloy sampling resistor that excels in accuracy, power, and stability, and is an indispensable component in many high-performance electronic devices. Both Shenzhen Shunhai Technology Co., Ltd. and Huanian Mall are officially authorized and reliable channels for procurement.
