Surface Mount Aluminum Electrolytic Capacitors NACZ Series

Category: Capacitors, Electronics, Nic Components Corp

Overview

The NACZ Series datasheet presents detailed information about the Surface Mount Aluminum Electrolytic Capacitors designed primarily for applications requiring high ripple current and low impedance. The capacitors are suitable for various electronic devices, such as DC-DC converters and DC-AC inverters, and are constructed for seamless integration with surface mount technology (SMT).

Features

V-Chip construction optimized for surface mounting
Very low impedance and high ripple current capacity at 100 kHz
New designs cater to an expanded capacitance value (CV) range, reaching up to 6800uF
High-temperature reflow capability with the “M1” version
RoHS compliant and designed for automatic mounting and reflow soldering
Meets the standards of AEC-Q200, which includes all homogeneous materials

Characteristics

The NACZ series boasts low Equivalent Series Resistance (ESR) and operates effectively across a broad temperature range from -55°C to +105°C. The capacitors have a rated voltage ranging from 6.3Vdc to 50Vdc and a capacitance tolerance of ±20%. Their performance is reliable in high-frequency applications, given the provision of liquid electrolyte for enhanced stability.

Capacitance and Leakage

The rated capacitance range of these components extends from 4.7uF up to 6800uF. The maximum leakage current is specified as either 0.01CV or 3μA, whichever value is greater, observed after a duration of 2 minutes at 20°C.

Temperature Stability and Impedance Ratio

NACZ capacitors maintain impedance stability under varying temperatures, with an impedance ratio from -40°C to +20°C for different rated voltages. This characteristic ensures their reliability in different operating environments.

Load Life

The capacitors’ load life is tested at 105°C, promising a capacitance change within +25% of the initial measured value, and a tan δ (dissipation factor) less than 120% of the specified maximum value; testing durations vary by diameter, with 1000 hours for 6mm diameter cases and up to 2000 hours for 12.5mm diameter cases.
