Introduction to the TSL series of Tian Er anti sulfurization resistors

The Ever Ohms TSL series sulfide resistant metal film resistors are high-performance components designed specifically for harsh environments. The following provides a detailed introduction from three dimensions: technical characteristics, application scenarios, and performance advantages:
1、 Core technical characteristics
Breakthrough in sulfur resistance performance
By using special metal film materials and sealing processes, it can effectively resist sulfide corrosion in sulfide containing environments (such as industrial waste gas, automobile exhaust, chemical workshops), avoid resistance drift or open circuit failure, and increase the service life by 3-5 times compared to ordinary resistors.
Through salt spray test (96 hours without corrosion) and high temperature and high humidity test (85 ℃/85% RH, 1000 hours), ensure stable operation in humid and corrosive environments.
Excellent electrical performance
Low resistance range: covering 0.05 Ω to 100 Ω, supporting high-precision current detection (such as current sampling in BMS battery management system).
Low temperature drift characteristics: The temperature coefficient (TCR) is as low as ± 50ppm/℃, and the resistance fluctuation within a wide temperature range of -55 ℃ to+170 ℃ is less than 0.1%.
Low inductance design: parasitic inductance ≤ 0.5nH, suitable for high-frequency switching circuits (such as DC-DC converters, motor drives).
Balance between power and accuracy
The rated power reaches 3W (2512 package) and can withstand instantaneous overload current (such as industrial equipment startup shock).
The resistance accuracy is ± 1% (some models can reach ± 0.5%), meeting the requirements of precision instruments for parameter consistency.
Environmental Protection and Reliability
Compliant with RoHS, halogen-free and lead-free standards, certified with AEC-Q200 automotive grade (some models), suitable for automotive electronics.
The packaging forms are diverse (0402 to 2512), compatible with SMT surface mount technology, and improve production efficiency.
2、 Typical application scenarios
Industrial Automation
Servo motor drive, PLC control module, current sampling and current limiting protection in industrial power supply.
Automotive Electronics
Car charger (OBC), battery management system (BMS), motor controller, resistant to high temperature and sulfurization environment in the engine compartment.
communication equipment
5G base station power module and optical module temperature control circuit ensure signal transmission stability.
In the field of new energy
Current detection and balancing circuits in photovoltaic inverters and energy storage systems.
Consumer Electronics
Fast charging circuits for portable devices such as laptops and drones, balancing small size and high reliability.
3、 Selection suggestions
Low resistance and high-precision scenarios: TSL series 0.05 Ω -1 Ω models are preferred, such as TSL2512 series (3W power, ± 1% accuracy).
High frequency application: Choose the 0402/0603 small package model for lower parasitic inductance.
Automotive grade requirement: Confirm that the model suffix contains "- Q" (such as TSL1206-Q) and meets the AEC-Q200 standard.
summarize
The Tian Er TSL series anti sulfide metal film resistors have solved the reliability problem of traditional resistors in harsh environments through material innovation and process optimization, becoming the preferred component for high reliability circuit design in industries such as industry, automobiles, and new energy. Its performance advantage is not only reflected in its ability to resist sulfurization, but also in the balance between full temperature stability and high-precision current detection, which helps the equipment to operate stably for a long time under extreme conditions.
