UUN0J332MNJ1MS

The UUN0J332MNJ1MS from Nichicon is a chip-type, bi-polarized aluminum electrolytic capacitor designed for surface-mounting on high-density printed circuit boards. It provides 3.3 mF capacitance at a 6.3 V rating in an SMD can-style package, targeted for general-purpose electronic designs that require high capacitance in a compact surface-mount form.

Key value propositions include a bi-polarized design for versatility across signal and power circuits, a wide operating temperature range from −55 °C to +105 °C, and endurance specified for elevated-temperature operation, making it suitable where long-term stability under thermal stress is required.

Key Features

• Chip-Type, Surface-Mount Package Compact radial can SMD package designed for automated mounting on carrier tape, enabling high-density PCB layouts and machine assembly.
• Bi-Polarized Construction Bi-polarized design supports circuits where polarity may reverse, providing application flexibility compared with polarized types.
• High Capacitance & Voltage 3.3 mF nominal capacitance at a 6.3 V rated voltage for bulk energy storage and decoupling in compact board real estate.
• Wide Operating Temperature Range Rated for −55 °C to +105 °C to maintain performance across demanding thermal environments.
• Endurance at Elevated Temperature Specified for 2000 hours at 105 °C with polarity inversion intervals noted in the endurance test, providing a measurable reliability baseline for high-temperature applications.
• Ripple Current Capability Rated ripple current up to 920 mA at 120 Hz and 1.058 A at 10 kHz, supporting applications with significant AC or switching currents.
• Compliance RoHS-compliant per 2011/65/EU and (EU)2015/863, supporting environmental and regulatory requirements.
• Board Land Pattern Recommended surface-mount land size: 1.83 × 1.83 cm to aid PCB layout and assembly planning.

Typical Applications

• General-purpose electronic circuits – Bulk decoupling and energy storage on high-density PCBs where a surface-mount, high-capacitance solution is required.
• Signal and power modules – Circuits that benefit from a bi-polarized capacitor for handling bidirectional or varying-polarity signals and power flows.
• Thermally demanding environments – Designs requiring components rated from −55 °C to +105 °C with specified endurance at elevated temperature.

Unique Advantages

• High capacitance in an SMD can Provides 3.3 mF in a chip-type radial can SMD package to reduce the board area compared with discrete through-hole alternatives.
• Bi-polarized flexibility Eliminates polarity constraints for circuits that may experience reverse voltage, simplifying design choices for AC-coupled or bidirectional paths.
• Defined high-temperature endurance 2000 hours at 105 °C (with polarity inversion intervals per endurance test) offers a quantifiable durability metric for thermal stress planning.
• Measured ripple performance Ripple ratings of 920 mA (120 Hz) and 1.058 A (10 kHz) enable designers to match the capacitor to expected AC and switching currents.
• Assembly-ready SMD format Compatible with automatic mounting machines and supplied in carrier tape form for efficient, repeatable PCB assembly.
• Regulatory compliance RoHS compliance supports inclusion in products targeting regions with restricted substances requirements.
