Surface Mount Aluminum Electrolytic Capacitors NACVF Series

Category: Capacitors, Electronics, Nic Components Corp

Overview

The NACVF Series datasheet presents information on surface mount aluminum electrolytic capacitors designed for high voltage applications. These capacitors are characterized by cylindrical V-chip construction and are suitable for reflow soldering. The series complies with RoHS directives and harbors a high-voltage capability ranging from 160VDC to 450VDC. The capacitors are available in various case sizes, ranging from 10mm x 14mm to 18mm x 22mm. Additionally, they exhibit a long life span, rated at 5000 hours at an operating temperature of 105°C.

Key Characteristics

These capacitors operate within a temperature range of -25°C to +105°C and have capacitance values from 2.2 to 100µF, demonstrating a capacitance tolerance of ±20%. The datasheet lists specific leakage current and tan δ (dissipation factor) maximum values depending on the voltage rating. The stability at low temperature for these capacitors is described by the impedance ratio at 120Hz between -25°C and +20°C.

Performance and Durability

The NACVF Series offers different durability performances dependent on the case size: 3000 hours for 10 x 14mm, 4000 hours for 10 x 18mm, and 5000 hours for 18mm diameter capacitors at 105°C & rated voltage. Post endurance, the capacitance change is within +20% of the initial measured value, tan δ remains under 200% of the specified value, and leakage current stays below the specified maximum.

Physical Dimensions and Land Patterns

Physical dimensions are provided for each case size, specifying diameter (Do), length (Lmax), the diameter including overmould (A), the length including overmould (B), terminal width (I), and terminal pitch (P), with appropriate tolerances listed. Additionally, recommended land pattern dimensions are detailed for various case sizes to facilitate proper mounting on printed circuit boards.
