The NACEW Series datasheet describes a range of surface mount aluminum electrolytic capacitors designed for a wide temperature range and suitable for reflow soldering. These capacitors meet the AEC-Q200 standard for automotive applications, though acquisition of supporting test data is recommended by contacting NIC.
Features and Characteristics
Construction: The capacitors are designed with a cylindrical V-Chip construction and are developed to endure wide temperatures ranging from -55°C to +105°C. Some specific models are characterized to operate at a minimum of -40°C. The capacitors come in rated voltage ranges from 6.3 to 100Vdc and capacitance ranges from 1.0 to 12,000µF. Moreover, they are able to withstand a leakage current specified as the greater of 3mA or 0.01CV after two minutes at 20°C.
Performance: At 120Hz/20°C, the maximum dissipation factor (tan δ) varies depending on the capacitance, ensuring efficient operation for different applications. The capacitors demonstrate excellent stability in low temperatures with an impedance ratio that varies with temperature and size specifications.
Reliability: Tested for load life reliability, the capacitors can withstand +105°C for periods ranging from 1000 to 2000 hours (size dependent), with post-test capacitance change within ±25% of the initial measured value, tan δ remaining less than 200% of the specified maximum value, and leakage current staying below the specified maximum.
Product Coding and Compliance
The part number system for the NACEW series includes information on the capacitance, voltage, size, and tolerance. For example, the part number NACEW 331 M 35V 10×10.5 identifies specific attributes such as the capacitance code, voltage rating, and physical dimensions. Also noted is compliance with RoHS directives and information on the termination material which includes tin and bismuth alloys or pure tin.
