On circuit boards, ordinary thick-film resistors can complete most basic current limiting and voltage dividing tasks. However, when devices require stable and repeatable signal sampling and reference voltage output, ordinary resistors are prone to expose their shortcomings: resistance value drift under high and low temperature environments, slow deviation after long-term power-on, directly causing inaccurate sampling, system false alarms, and even failure of the entire machine calibration.
The Tian Er TR series high-precision thin-film SMD resistors, relying on metal thin-film sputtering technology, provide a stable resistance value support for precision sampling and reference voltage division circuits in various devices.
Vacuum Sputtering Thin-Film Technology: Achieving High Precision and Low Drift from the Bottom
The Tian Er TR series high-precision thin-film resistor uses vacuum sputtering nickel-chromium thin-film technology, forming a uniform and dense conductive metal film on a high-purity ceramic substrate, and then completing resistance value calibration through high-precision laser trimming, which is fundamentally different from the particle conduction structure of conventional thick-film resistors.
This continuous and uniform thin-film structure brings two core performance advantages:
Firstly, resistance value is controllable and has excellent temperature coefficient performance. When the ambient temperature fluctuates, the resistance value drift is much lower than that of thick-film devices. Under the working conditions of long-time continuous operation and temperature fluctuations, it can stably maintain the parameter consistency of voltage division, signal sampling, and voltage reference circuits, significantly reducing system errors caused by component parameter drift.
Secondly, current noise is lower and parasitic parameters are smaller. The uniform metal thin-film layer has inherently lower current noise, and the levels of parasitic inductance and parasitic capacitance are also lower. In weak signal acquisition and high-frequency signal processing circuits, it can effectively reduce signal distortion and ensure the integrity and purity of the signal chain.
Wide Temperature Range + Full Packaging: Suitable for Complex Working Conditions and Miniaturized Design
For complex and changing application environments, this series of resistors supports an ultra-wide operating temperature range of -55°C to +155°C.
Whether it's outdoor industrial control equipment, portable testing instruments, or communication base station modules with large temperature differences and complex working conditions, they can continuously maintain stable resistance output, reduce performance degradation caused by alternating high and low temperatures, and ensure reliable operation of the equipment under extreme conditions.
In terms of packaging specifications, the product covers all mainstream SMD sizes from 0201 to 2512, perfectly matching the needs of miniaturized PCB layout, meeting the requirements of high-density circuit board mounting; at the same time, it is compatible with conventional SMT reflow soldering processes, facilitating batch production and assembly on the production line, allowing seamless connection between R&D and mass production.
Compliance and Protection: Ensuring Stable Long-Term Operation, Cost-Effective and Hassle-Free
Reliability and compliance are the core evaluation criteria for industrial-grade components.
The TR series high-precision thin-film SMD resistors strictly follow the RoHS regulations, being lead-free and halogen-free, meeting global mainstream electronic product environmental protection requirements, and can be directly adapted to export hardware projects without additional compliance verification.
The device surface adopts a dedicated protective coating structure, significantly improving moisture resistance and anti-environmental corrosion capabilities. Under long-term continuous power load, the change in resistance value is kept at a very low level, with minimal aging drift, not only extending the service life of the entire machine equipment, but also reducing the frequency of post-sales equipment calibration, effectively reducing the maintenance costs throughout the lifecycle.
