Surface Mount Aluminum Electrolytic Capacitors NACEW Series

Category: Capacitors, Electronics, Nic Components Corp

Overview

The NACEW Series datasheet describes Surface Mount Aluminum Electrolytic Capacitors designed for a wide temperature range and suitable for reflow soldering. The series meets AEC-Q200 requirements, implying its suitability for automotive applications. The document includes details on the rated voltage and capacitance range, operating temperature, leakage current, maximum tan delta at 120Hz/20°C, low temperature stability, impedance ratio, load life test outcomes, and part number coding system.

Features and Characteristics

These capacitors offer a cylindrical V-chip construction and are aimed at applications that demand a wide temperature range of -55°C to +105°C (with a specific limit at 100V being -40°C to +105°C). The rated voltage range for the series is between 6.3Vdc and 100Vdc, and the available capacitance range spans from 1.0μF to 12,000μF.

Leakage current specifications are set at the greater of 0.03CV or 3mA after two minutes at 20°C, with distinct maximum allowable leakage currents outlined for various rated voltages (WV). At 120Hz/20°C, the datasheet specifies the maximum tan delta for various capacitance values, supporting a detailed understanding of the capacitor’s dissipation characteristics across different sizes.

Low Temperature Stability and Load Life Performance

The capacitors exhibit low temperature stability, with impedance ratios between the measurement at -55°C and +20°C at 120Hz remaining within acceptable boundaries. Capacitance changes post the load life test, which spans 1000 to 2000 hours at +105°C, remaining within +/- 25% of the initial measured value and tan delta being below 200% of the specific maximum value.

Part Number System

The part number system for the NACEW Series capacitors includes information on the series, capacitance value, tolerance code, voltage rating, case size, termination material composition, reel size, and designates whether the part is RoHS compliant.

Case Diameter and Termination Material

Different case diameters from 10mm to 16mm are offered with specifics on the termination material provided, ranging from a composition of 97% tin and 3% bismuth, to pure tin terminations.
