Surface Mount Aluminum Electrolytic Capacitors NACEW Series

Category: Capacitors, Electronics, Nic Components Corp

Overview

The NACEW Series datasheet details the specifications for Surface Mount Aluminum Electrolytic Capacitors designed by NIC Components Corp. These capacitors are constructed with a cylindrical V-chip and are RoHS compliant, ensuring adherence to environmental standards regarding the restriction of hazardous substances. The series is engineered to endure reflow soldering processes and is suitable for applications spanning a wide range of temperatures.

Electrical Characteristics

Capacitance Range: The capacitors have a capacitance range between 0.1 µF and 6,800 µF with rated voltage ranges from 6.3Vdc to 100Vdc. They exhibit operational temperature ranges from -40°C to +105°C. Capacitance tolerance is typically ±20% at 20°C.

Leakage Current: Max leakage current is the greater of either 0.01CV or 3μA, after a stabilization period of 2 minutes at 20°C.

Performance

The capacitors offer low ESR (Equivalent Series Resistance) and impressive low-temperature stability, with impedance ratios for various diameters provided to demonstrate performance at different temperatures. Load life tests demonstrate the capacitors’ stability and endurance, with the capacitance change kept within ±25% of the initial measured value after specified durations at different temperature thresholds. For example, the capacitors are tested at +105°C for 1,000 hours, and at +85°C for 4,000 hours, to ensure reliability and lifespan. Furthermore, the Tan δ (dissipation factor) remains less than 200% of the specified maximum value after equivalent endurance periods.

Product Range

The NACEW series offers a standard product and case size table that lists a variety of capacitor sizes along with their working voltage and capacitance code. Diameter and length increments are represented in millimeters (e.g., 4×5.5mm), and working voltage is presented in Vdc (e.g., 6.3Vdc to 100Vdc). Capacitance values are identified by codes such as R10, R22, with specific values denoted for each available tolerance (e.g., 10% tolerance).

Precautions

The datasheet concludes by urging users to review safety notes, correct usage, and precautions available in the NIC Electrolytic Capacitor catalog, as well as on the NIC Components Corp website. The company also encourages users to consult with NIC technical support for clarification regarding specific application processes or any uncertainties.
