On January 27, 2026, the R&D center of Shenzhen LeaKin Technology Co., Ltd. hosted a professional technical training session. Mr. Xie, the head of the Shenzhen office of Jiangsu NCT, served as the keynote speaker and provided the LeaKin Technology technical team with an in-depth explanation of the processes and applications of precision alloy resistors. This training session not only facilitated technical exchange but also marked the launch of a deepened collaboration between the two companies.

01 Strong Alliance

Shenzhen LeaKin Technology Co., Ltd. (hereinafter referred to as “LeaKin Technology”) has been focusing on the R&D and sales of embedded solutions and electronic components since its establishment in 2013. Jiangsu NCT, on the other hand, boasts mature technological expertise and extensive industry experience in the field of precision alloy resistors.

During this training, Mr. Xie from NCT systematically introduced the technical features and application prospects of alloy resistors. LeaKin Technology highly praised NCT’s production control and quality inspection processes, noting that its equipment is fully equipped and highly precise, meeting the requirements for both industrial-grade and military-grade products and having successfully obtained the relevant certifications.

The cooperation between the two parties has gone beyond a simple supply-and-demand relationship. LeaKin Technology plans to become a Tier-1 distributor for NCT, jointly developing high-end markets both domestically and internationally.

02 Understanding Alloy Resistors

Alloy resistors—also known as current-sensing resistors—are specialized resistor components made from alloy materials. Leveraging the inherent properties of these alloy materials, they enable precise measurement and control of current in electrical circuits.

Operating Principle: The operating principle of alloy resistors is based on Ohm’s Law. When current flows through an alloy resistor, a voltage drop proportional to the current is generated across its terminals. By measuring this voltage value, the magnitude of the current in the circuit can be accurately calculated. Unlike conventional resistors, alloy resistors employ a four-terminal design. By separating the current-carrying terminals from the voltage-sensing terminals, this design effectively eliminates the influence of lead resistance on measurement accuracy, thereby significantly enhancing the precision of current measurements.

Core features: Alloy resistors boast low resistance values (1 mΩ to 15 mΩ), high precision (with errors controllable within ±0.1%), and a low temperature coefficient (as low as ±10 ppm/℃). These characteristics enable alloy resistors to maintain stable performance over a wide temperature range, without significant resistance drift caused by changes in ambient temperature.

03 Application Areas

As a key component for current sensing, alloy resistors have been widely used in numerous fields. In industrial applications, alloy resistors are indispensable components in variable-frequency drives, industrial servo drives, and energy storage systems.

In particular, the braking resistor can convert the regenerative electrical energy generated when the motor slows down into thermal energy, thereby preventing overvoltage faults in the inverter and ensuring stable system operation. In the automotive electronics field, alloy resistors are widely used in the BMS (Battery Management System) and BCM (Body Control Module) of new-energy vehicles, enabling precise monitoring of current.

Alloy resistors are also used in consumer electronics such as fast-charging devices, smartphones, and laptops. In high-end applications—including medical equipment, precision instruments, and military products—alloy resistors’ high precision and stability are simply irreplaceable. As electronic products continue to evolve toward intelligence, miniaturization, and energy efficiency, the application prospects for alloy resistors will become even broader.

04 Prospects for Cooperation

The strategic collaboration between LeaKin Technology and NCT is based on the high degree of alignment between the two companies in terms of market positioning and technological complementarity. LeaKin Technology already has a strong market presence in the industrial, medical, telecommunications, and defense sectors, while NCT focuses exclusively on the R&D and production of alloy resistors.

The collaboration between the two parties will fully leverage synergies. By combining LeaKin Technology’s market channels with NCT’s technological expertise, we will be able to provide customers with higher-quality products and solutions. This collaboration goes beyond a simple agency relationship; the two parties also plan to engage in deep cooperation in areas such as product customization and technology R&D, jointly accelerating the localization of high-end electronic components.

With the rapid development of emerging technologies such as 5G, new-energy vehicles, and artificial intelligence, demand in the high-end alloy resistor market will continue to grow. The collaboration model between LeaKin Technology and NCT will serve as a benchmark for collaborative innovation across the upstream and downstream sectors of the electronic components industry, injecting fresh momentum into the technological advancement and market expansion of China’s high-end electronic components industry.
