Surface Mount Aluminum Electrolytic Capacitors NACZF Series Datasheet

Category: Capacitors, Electronics, Nic Components Corp

Overview

The datasheet provides detailed information on the NACZF Series Surface Mount Aluminum Electrolytic Capacitors by NIC Components Corp. These capacitors are designed primarily for surface mounting, offering new designs with high capacitance values up to 6800μF, low impedance, and high ripple current handling at 100kHz. They are available in various case sizes such as 12.5mm x 17mm, 16mm x 17mm, 18mm x 17mm, and 18mm x 22mm, with a wide termination style that suits high vibration applications.

Features and Compliance

The capacitors feature a long operational life of 5000 hours at +105°C, are RoHS compliant, and are suited for reflow soldering processes. Moreover, these components are designed to meet the rigorous AEC-Q200 standards, which is critical for automotive applications. Homogeneous materials used in these capacitors ensure compliance with environmental regulations. For automotive equipment, parts are available with a “Y” option and are sourced from a TS-16949 certified production site, underlining their quality and reliability.

Electrical Characteristics

Electrical specifications cover a wide operating temperature range from -40°C to +105°C and a rated voltage range of 6.3 to 100Vdc. The capacitors’ capacitance tolerance is specified at ±20% (M), with maximum leakage current after 2 minutes being the greater of 0.01CV or 3μA. They can handle surge voltages well above their rated working voltage, indicating robustness against voltage spikes.

Performance Parameters

Key performance parameters such as low temperature stability, characterized by an impedance ratio at 120Hz between -25°C and +20°C, and high-temperature load life, where the capacitance change is within +20% after 5000 hours at +105°C, are specified. Additional metrics include dissipation factor (Tan &), maximum ripple current, and maximum impedance, ensuring that engineers can select the appropriate capacitor for their specific application needs.

Product Options and Part Number System

Various product options are available, such as an optional wide terminal (WT) and a plastic reel for surface mount packaging. The part number system listed describes how to denote the series, capacitance, voltage, case size, tolerance, and other relevant product attributes, including distinctions for automotive-grade components. This system enables precise identification and ordering of the required capacitor.
