Surface Mount Aluminum Electrolytic Capacitors NACY Series

Category: Capacitors, Electronics, Nic Components Corp

Overview

The NACY Series datasheet presents information on surface mount aluminum electrolytic capacitors designed for automatic mounting and reflow soldering. These capacitors are RoHS compliant and feature a cylindrical V-chip construction that meets the AEC-Q200 standards for automotive qualifications; however, consumers are encouraged to contact NIC for supporting test data, particularly concerning the anti-vibration terminations.

Features

The capacitors from the NACY Series are characterized by low impedance at 100KHz, which can be up to 20% lower compared to the NACZ series. They are also designed to operate over a wide temperature range from -55°C to +105°C. They are suitable for surface mounting with their V-chip construction and are engineered for use with automatic mounting equipment and reflow soldering techniques.

Characteristics

The datasheet specifies the capacitors’ rated capacitance range which lies between 2.2 and 6800 pF. They can operate within a temperature range of -55°C to +105°C. At 120Hz and a temperature of +20°C, the capacitors possess a capacitance tolerance of ±20%. Further specifying the product’s reliability, the datasheet gives details on the maximum leakage current after two minutes at 20°C: it is the lesser of 0.01 times the capacitance value times the rated voltage (CV), or 3 µA.

Voltage Ratings and Tangent of Loss Angle (Tan δ)

The capacitors are rated for various working voltages (WV) from 6.3 to 100Vdc, with surge voltages (SV) from 13 to 160Vdc outlined in a given table. For different capacitance values, the datasheet lists the Tan δ (a measure of electrical losses) at 120Hz and 20°C. These values vary with the capacitance, particularly for capacitance values such as 1500 pF, 2200 µF, 3300 pF, 4700 pF, and 6800 pF.

Stability and Life Test

Low-temperature stability is demonstrated by an impedance ratio at 120 Hz, presenting a Z(-40°C)/Z(+20°C) metric. For the load life test at +105°C, capacitors exhibit a capacitance change within +25% of the initial measured value, with durations ranging from 1000 to 2000 hours depending on the device diameter. The leakage current post test is to remain under the specified maximum.

Standard Product and Case Size Specifications

The capacitors come in an array of standard case sizes and product options with varying dimensions expressed in millimeters (mm), such as diameter (D) by length (L). The working voltage capabilities are similarly presented alongside the corresponding case size and capacitance codes. To illustrate, this includes case sizes like 6.3×6.3 mm for smaller capacitance codes (2R2) up through larger sizes like 16×17 mm for capacitances marked as 6800 µF (code 682).
