Surface Mount Aluminum Electrolytic Capacitors NACP Series

Category: Capacitors, Electronics, Nic Components Corp

Overview

The NACP Series datasheet outlines the specifications of Surface Mount Aluminum Electrolytic Capacitors that adhere to RoHS [Restriction of Hazardous Substances] compliance. These capacitors are touted for their cylindrical V-chip construction, low profile design with a maximum height of 4.6mm, and suitability for reflow soldering.

Capacitance Characteristics

The capacitors come with a rated voltage range of 4 to 50V dc and a capacitance range between 1.0μF and 220μF. The operating temperature span specified is from -40°C to +85°C. These capacitors have a capacitance tolerance of ±20% (M) and boast a maximum leakage current of either 0.01CV or 3μA after 2 minutes at 20°C, whichever is greater.

Additional Ratings

Surge voltage (S.V.) ratings per Working Voltage (W.V.) range from 6.3Vdc to 50Vdc and corresponding Surge Voltage ratings fall between 7Vdc to 63Vdc. At 120Hz/20°C, Tanδ (Dissipation Factor) values vary from 0.40 for a W.V. of 4Vdc down to 0.12 for a W.V. of 50Vdc, indicating efficiency and stability of the capacitor under varying electrical loads.

Durability and Performance

In terms of performance, under a load life test of 85°C for 1,000 hours, the capacitors exhibit a capacitance change within ±5% of the initial measured value. They maintain a Tanδ of less than 200% of the specified initial value with a leakage current below the specified value.

Physical Dimensions and Variants

The datasheet lists standard product case sizes, which include diameters (D) and lengths (L) in millimeters (mm) ranging from 4×4.5 to 6.3×4.5, as well as capacitance values for various working voltages. The detailed dimensions express the capacitor size options, tabulating tolerance levels for the body diameter, length, and lead spacing.

Part Number System

An example part number NACP 470 M 6V 6 3×45 IR is given for the capacitors, which is decoded to indicate the series, capacitance code, working voltage, tolerance, size, and packing detail respectively. The RoHS compliance ensures the usage of minimum 97% tin (Sn) and a maximum of 3% bismuth (Bi).
