Overview and Features
The datasheet provides information on the NACX Series of Surface Mount Aluminum Electrolytic Capacitors, which are characterized by their cylindrical V-chip construction and suitability for reflow soldering. They are engineered to operate efficiently with a very low impedance at 100kHz. Notable for their wide operating temperature range of -55°C to +105°C, these capacitors have a maximum height of 5.5mm accommodating various homogeneous materials. Additionally, they possess an anti-solvent feature for up to two minutes. Compliance with RoHS directives and the ability to meet AEC-Q200 requirements (test data available upon request) indicates their reliability and suitability for automotive and other rigorous applications.
Capacitance and Voltage Ratings
The NACX capacitors are available in a rated voltage range from 6.3V to 63V, with capacitance options ranging from 1.0µF to 150µF. The products exhibit a variation in capacitance tolerance of ±20% (M) and allow for an optional tolerance of +10% (K) on most values. The capacitors’ leakage current at 20°C after two minutes does not exceed 0.01CV or 3µA, depending on the greater value for each voltage rating.
Electrical Characteristics
These capacitors offer excellent low and high temperature stability evaluated through impedance ratios at varying temperatures. The high temperature load life is guaranteed for up to 1000 hours at 105°C, ensuring a capacitance change within ±25% of the initial measured value and a Tan δ less than 200% of the specified value. The datasheet also provides maximum tan δ, surge voltage (S.V.), and standard product sizes and dimensions.
Physical Dimensions and Part Number System
Physical dimensions for the capacitors cover case sizes, maximum length, and the dimensions for terminals and spacing (D, L, A, B, and P). The part number system is detailed, indicating the significance of each section, such as series, capacitance code, tolerance code, working voltage, and packaging designations, making it easier to select the appropriate component for specific applications.
Standard Values and Specifications
Standard values are provided for rated capacitance, working voltage, dissipation factor, ripple current, and impedance. Moreover, there are outlines available for load life hours and NIC part numbers for specific capacitance and voltage ratings.
