The core advantage of Tian'er Metal Film Resistors: providing high reliability guarantee for precision circuits
In the current sampling circuit of the BMS system for new energy vehicles, a Tian'er metal film resistor is ensuring long-term accuracy of battery status monitoring with an annual drift rate of less than ± 0.5%.
With the development of electronic products towards precision and high performance, the importance of basic electronic components is increasingly prominent. Among numerous resistor products, Tian Er metal film resistors have gradually become a popular choice in high-end application fields such as industrial control, automotive electronics, and precision instruments due to their excellent electrical performance, environmental adaptability, and reliability.
Tian'er Metal Film Resistors have solved many performance bottlenecks of traditional resistors in high demand application scenarios through unique technological paths and process innovations.
01 Accuracy and stability: meet demanding circuit requirements
In precision circuits, the accuracy and long-term stability of resistors often determine the performance limit of the entire system. The performance of Tian Er metal film resistors in this regard is commendable.
The resistance accuracy of Tian'er metal film resistors can reach a level of ± 0.1% or even higher. This level of accuracy is sufficient to meet the needs of most precision measurements and high-precision analog circuits. In applications that require precise current sampling or voltage reference, such accuracy ensures the accuracy of the signal link.
More noteworthy is its temperature stability. The temperature coefficient (TCR) of Tian Er metal film resistors can usually be controlled within the range of ± 25ppm/℃ to ± 100ppm/℃, and some high-performance models can even reach lower levels.
This means that even in environments with drastic temperature changes, the fluctuation of resistance can be strictly limited, ensuring the consistency of circuit performance.
In terms of long-term stability, Tian'er Metal Film Resistors use high-purity ceramic cores and nickel chromium alloy film layers. Combined with automated laser fine-tuning technology, it ensures the consistency of resistance values between products of the same batch and individual products at different stages of use.
02 Environmental adaptability: Coping with harsh working conditions
Modern electronic devices often need to work reliably in various harsh environments, and Tian'er metal film resistors demonstrate excellent environmental adaptability through multiple protective designs.
The anti sulfurization performance is a major highlight of Tian'er metal film resistors, especially in the TSL series. In sulfur-containing environments, the metal parts of ordinary resistors are prone to react with gases such as hydrogen sulfide, leading to resistance drift and even open circuit failure. The Tian'er TSL series uses special metal film materials and sealing processes, which increase the service life by 35 times compared to ordinary resistors.
The working temperature range of Tian Er metal film resistors is wide, with common models covering 55 ℃ to+155 ℃, and some models even reaching 55 ℃ to+170 ℃. This wide temperature range characteristic enables it to adapt to various application scenarios ranging from cold to high temperature environments.
03 High frequency and electrical performance: optimizing signal integrity
In high-frequency circuits and high-speed signal processing applications, the high-frequency characteristics of resistors directly affect the overall performance of the system. The design of Tian Er metal film resistors in this regard is well considered.
The Tian Er metal film resistor adopts optimized structural design and material selection to achieve low parasitic inductance and capacitance characteristics. This characteristic is particularly important in high-frequency applications, as it can reduce signal distortion and reflection, ensuring signal integrity.
In terms of electrical safety performance, Tian Er metal film resistors perform outstandingly. Its working voltage is usually adapted to different circuit design requirements and can withstand high instantaneous voltage surges. The outsourced flame retardant coating further enhances the product's ability to withstand instantaneous high voltage and surges.
04 Structural Design and Reliability: Ensuring Long term Stable Operation
The careful design of the physical structure of the Tian'er metal film resistor provides a solid guarantee for its long-term stable operation.
The use of a three-layer terminal electrode structure is an innovative design of Tian'er Metal Film Resistors. This structure typically includes an inner layer of silver palladium, a middle layer of nickel, and an outer layer of tin, effectively reducing contact resistance, minimizing the generation of hot spots, and optimizing heat dissipation performance.
In terms of material selection, the Tian Er metal film resistor uses a high thermal conductivity ceramic substrate (such as 96% alumina), which significantly improves the thermal conductivity efficiency compared to conventional substrates. The optimized heat dissipation path design enables heat to be quickly conducted from the resistive film layer to the PCB, avoiding performance degradation or failure caused by local overheating.
05 Certification and Environmental Protection: Compliant with Global Market Standards
In the global electronic components market, product certification and environmental compliance have become basic requirements. Tian'er Metal Film Resistors have established a complete system in this regard.
The Tian'er metal film resistor has passed the IATF 16949 automotive grade certification, and some models also comply with the AECQ200 standard, which can be directly applied to automotive electronic systems. These certifications not only represent the high reliability of the product, but also provide a passport for manufacturers to enter the automotive supply chain.
In terms of environmental protection, Tian'er metal film resistors comply with international environmental directives such as RoHS and REACH, and do not contain harmful substances. This environmental compliance enables it to smoothly enter major global markets and meet the needs of various customers for green products.
06 Application areas and cost-effectiveness: expanding market space
