YMIN NHX Series Aluminum Electrolytic Capacitors: High-Reliability Industrial-Grade Power Storage Solutions
In industrial power electronics, capacitor performance directly impacts overall system stability and efficiency. With a design life of 2000-5000 hours at 105°C, ultra-low ESR, high ripple current capability, and a compact design, the YMIN NHX series aluminum electrolytic capacitors are ideal for demanding applications such as industrial power supplies, inverters, and automotive electronics.
Core Technical Features
The NHX series utilizes advanced electrode foil processing and electrolyte formulation technologies, delivering exceptional performance across multiple key performance indicators. With a rated voltage range of 16V to 160V and capacities ranging from 6.8μF to 3300μF, these products meet the needs of most industrial applications. Under test conditions of 20°C and 120Hz, the loss tangent of these capacitors can reach as low as 0.08, significantly exceeding the industry average and ensuring the capacitor's low energy loss characteristics at high frequencies.
In terms of temperature characteristics, the NHX series demonstrates excellent environmental adaptability. At extremely low temperatures of -55°C, the impedance ratio is ≤2.5, and at -25°C, the impedance ratio is ≤2.0. This ensures reliable startup and stable operation in harsh environments. The product's leakage current is strictly controlled within 0.01CV, demonstrating excellent insulation performance and material stability.
Structural Design and Reliability
The NHX series features a fully screw-type terminal design and is available in various sizes, ranging from Φ5mm to Φ16mm. The compact package design maximizes capacitance density within limited space. For example, the 16V/1000μF model measures only Φ10×12mm, saving over 30% installation space compared to traditional packages.
The product's insulation performance deserves special attention. The insulation resistance between the terminal and the housing exceeds 100MΩ, and the insulation voltage test has passed 2000V AC for one minute without any abnormalities. These safety features demonstrate a deep understanding of the actual needs of industrial applications.
Endurance testing results show that, after 2000-5000 hours of continuous operation at a 105°C ambient temperature and with rated voltage and ripple current applied, the capacitance change does not exceed ±30%, the loss tangent does not exceed 200% of the initial specification, and the leakage current remains within the initial specification. These data fully demonstrate the product's reliability under long-term continuous operation.
Ripple Current Withstand Capacity
Ripple current withstand capacity is a key performance indicator for power capacitors. For example, the 16V/1500μF model has a rated ripple current of 3200mA. More importantly, the product's ESR is as low as 15mΩ at 100kHz, making it particularly suitable for high-frequency switching power supply applications.
As frequency increases, the capacitor's ripple current withstand capacity significantly increases. At 100kHz, the ripple current withstand capacity of most models is 30-40% higher than the baseline 120Hz condition. This characteristic makes the NHX series particularly suitable for modern high-frequency switching power supplies and inverter applications.
Application Scenario Analysis
In the industrial inverter sector, the NHX series demonstrates unique value. A certain brand's 22kW inverter uses a 35V/470μF model as the DC link capacitor. Under full-load operation, the capacitor temperature rise is kept below 18K, and the actual ripple current reaches 85% of the rated value. After 24 months of continuous production operation, the capacity degradation rate is only 4.2%, fully meeting the design life requirements of the equipment.
In the automotive electronics sector, the NHX series' AEC-Q200 certification features are fully utilized. A new energy vehicle onboard charger uses a 63V/100μF model. After 3000 hours of continuous operation at an ambient temperature of 85°C, all parameters remain within specification. The product has passed rigorous mechanical vibration and temperature cycling tests, ensuring reliability in vehicle driving environments.
In the telecommunications power supply sector, the NHX series' high-frequency characteristics are particularly important. A data center server power supply uses a 100V/220μF model with an ESR of only 25mΩ at a 100kHz switching frequency, effectively reducing the temperature rise of the power module and boosting system efficiency to 94.5%. The product's long life reduces maintenance requirements and lowers overall operating costs.
Technological Innovation and Quality Assurance
The success of the NHX series is due to a number of technological innovations. The high-purity electronic aluminum foil used undergoes a special etching process, increasing its effective surface area by over 50% compared to ordinary aluminum foil. This is the foundation for achieving high capacitance and low ESR. The electrolyte formula has been carefully optimized to maintain stable conductivity over a wide temperature range while effectively suppressing gas generation, ensuring a long product life.
In terms of production, YMIN has introduced a fully automated winding system to ensure consistent winding tension for each capacitor core pack. A vacuum impregnation process ensures that the electrolyte fully penetrates every corner of the core pack, eliminating potential bubbles and voids. A final aging screening process ensures that every product meets the designed performance specifications.
Environmental Protection and Compliance
The NHX series fully complies with the RoHS directive, and all materials are free of hazardous substances such as lead, mercury, and cadmium. AEC-Q200 certification demonstrates that the products meet the stringent standards of the automotive electronics industry. Furthermore, they meet CE certification requirements, ensuring seamless access to major global markets.
In terms of packaging and shipping, the products utilize anti-static and moisture-proof packaging to protect them from damage during transportation and storage. Each product is uniquely serialized for full traceability, providing customers with added assurance of quality.
