EVER OHMS Launches MAH2512 High-Power 5W Chip Resistor, Empowering Precision Circuit Applications Across Multiple Sectors
Recently, renowned electronic component manufacturer EVER OHMS officially launched the MAH2512 series high-power low-resistance chip resistor. Boasting a 5W rated power, excellent temperature stability, and precise current sensing performance, this product provides reliable circuit solutions for entertainment products, power supplies, measuring instruments, industrial products, battery management systems, and other fields, further enriching the market options for high-power chip resistors.
As a flagship product of EVER OHMS in the resistor sector, the MAH2512 series achieves multiple breakthroughs in core performance. Crafted with manganese-copper (MnCu) material, the product features low resistance and a low temperature coefficient (TCR ≤ ±50ppm/℃), with resistance values ranging from 1mΩ to 10mΩ and tolerance accuracies of ±1% (Grade F), ±2% (Grade G), and ±5% (Grade J), meeting the precise current sensing and voltage division requirements of various scenarios. In terms of power bearing capacity, the product supports a rated terminal temperature of 105℃ (1mΩ~3mΩ) and 85℃ (4mΩ~10mΩ) respectively, with a maximum rated current of up to 70.71A and a short-term overload current of 141.42A, enabling it to handle the harsh operating environment of high-power circuits with ease.
In terms of reliability design, the MAH2512 series is AEC-Q200 certified, fully compliant with RoHs standards, and meets halogen-free and lead-free environmental requirements. After undergoing multiple rigorous tests including high-temperature exposure, temperature cycling, biased humidity, and resistance to soldering heat, the product demonstrates excellent long-term stability: the resistance change rate is ≤ ±1% after 1000 hours of operation at 155℃, remains ≤ ±1% after 1000 temperature cycles from -55℃ to +155℃, and is ≤ ±0.5% during soldering (260℃/10 seconds), fully ensuring the long-term stable operation of circuit systems. In addition, the product exhibits outstanding mechanical performance, with core strength, terminal strength, and bending strength all passing industry-standard tests without fracture risks.
In terms of packaging and application adaptability, the MAH2512 series adopts a standard 2512-inch package (dimensions: 6.35±0.254mm × 3.05±0.254mm × 0.75±0.254mm) and provides a clear product marking scheme for easy production identification and assembly. The product supports both wave soldering and reflow soldering, with optimized recommended soldering parameters to adapt to industrial production processes. Customized pad design suggestions are also available to ensure soldering reliability and heat dissipation. For packaging, it uses a 7-inch reel with 4000 pieces per reel, meeting the requirements of automated assembly lines for SMD chip production, and has a shelf life of up to one year under storage conditions (25±5℃, humidity 60±20%).
A relevant person in charge of EVER OHMS stated that the launch of the MAH2512 series high-power chip resistor is the result of the company's technical accumulation in the high-power, high-precision resistor field combined with market demand. In the future, EVER OHMS will continue to focus on technological innovation in electronic components and provide more competitive product solutions for new energy, industrial control, consumer electronics, and other fields.
