Huade alloy resistor: a current sampling expert recognized by the market for its excellent performance
In the field of electronic components, Huade alloy resistors have become the preferred choice for many high-end applications due to their excellent performance and reliability.
In electronic circuit design, although resistors are small, they are everywhere. As a key component for current detection and power control, the performance of alloy resistors directly affects the stability and accuracy of the entire system.
As an electronic component brand originating from Taiwan, China, Walter has been deeply involved in the field of alloy resistance for decades since its establishment in 1968.
Through continuous technological innovation and strict quality management, Huade alloy resistors have demonstrated significant competitive advantages in high-end application fields such as automotive electronics, industrial control, and new energy.
01 Brand Strength: Deep Accumulation and Technological Inheritance
Huade Electronics is not a newcomer in the industry, but a senior electronic component brand with over 50 years of history.
In 2000, Huade Electronics established a production base in Wujiang, Jiangsu Province in the Yangtze River Delta region, greatly enhancing its production capacity.
2006 was a crucial year for the development of Huade resistor technology. The company obtained technical authorization for current sensing resistor related products from a major Japanese manufacturer, began to vigorously develop resistor components, and successfully obtained certifications from multiple well-known manufacturers.
Nowadays, Huade resistors have developed into the core supplier of A company's current sensing precision resistor products, and have entered the supply chain system of dozens of well-known domestic and foreign enterprises including Samsung, Xiaomi, Lenovo, Gree, BYD, etc.
02 Technical advantage: Excellent core performance indicators
High precision and low resistance coexist
Huade alloy resistors have extremely high resistance accuracy, with the STE series achieving an accuracy of ± 0.05% or even higher.
This high-precision characteristic plays a key role in the circuits of precision measuring instruments, medical equipment, and high-end communication devices.
At the same time, the Huade MSH series pure metal process resistors can achieve full resistance coverage (0.5m Ω~0.5 Ω) with an accuracy of ± 0.01%, which can meet the needs of high-precision scenarios such as medical equipment and precision measuring instruments.
Excellent temperature characteristics
The temperature coefficient (TCR) is one of the key indicators for measuring resistance performance. The TCR of Huade resistors is usually ± 50ppm/℃, and some products can even be as low as ± 10ppm/℃.
This means that the resistance value can remain highly stable within a wide temperature range of 55 ℃ to+150 ℃.
For example, the working temperature range of STE0603MW50R010F alloy resistor is 55 ℃~170 ℃, which is suitable for environments with large temperature changes.
High frequency performance and low inductance design
Huade alloy resistors have low inductance (H<5.0nH) and low electric couple effect (EMF<0.5uV/℃) at high frequencies of 1GHz.
This characteristic makes it perform excellently in high-frequency circuits and will not affect signal integrity due to inductance effects.
High power density and durability
Huade resistors use thick film technology and multi-layer structure design, with a power range covering 0.2W to 12W.
High power density is another highlight of Huade resistors. Taking STE0603MW50R010F as an example, a power capacity of 0.5W can be achieved in the small-sized package of 0603, which is particularly suitable for applications with limited space.
03 Product Series: Fully meet different application needs
Huade alloy resistors have launched multiple characteristic product series for different application scenarios:
STE series: Metal ceramic current sensing resistors, covering various package sizes such as 0603, 0805, 1206, 2010, 2512, with power ranging from 0.5W to 3W.
MSH series: High power resistors made of pure metal process, with a resistance range of 0.0005 Ω to 0.5 Ω and a power of 1W to 3W. The package sizes include 1206 and 2512.
MSTC/MHTC series: ultra-thin low resistance resistors with a resistance range of 0.001 Ω to 0.02 Ω, power of 0.2W to 1W, and package sizes from 0201 to 1206.
HFCL series: Four terminal Kelvin resistor, with a resistance range of 0.001 Ω to 0.25 Ω and an accuracy of ± 0.5% and ± 1%. It has low inductance and low thermocouple effect characteristics, suitable for high-precision current detection.
To meet the design requirements of engineers for circuit board dimensions, the Walder alloy resistors from 0201 to 5931 have been developed and mass-produced in all volumes and series.
