UUN1E471MNJ1MS

The UUN1E471MNJ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor from Nichicon’s UUN series, offering 470 µF capacitance at a 25 V rating. It is designed for surface mounting on high-density PC boards and is supplied for use with automatic mounting machines fed with carrier tape.

Built for general-purpose electronic designs that require bipolar operation over a wide temperature range, this part delivers higher capacitance in an SMD radial-can package while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — Rated at 470 µF and 25 V with a capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Bi-Polarized Construction — Bipolar design suitable for applications requiring reversible polarity; endurance testing includes polarity inversion every 250 hours during 2000 hours at 105°C.
• Temperature Range & Endurance — Operates from −55°C to +105°C; endurance specification is 2000 hours at 105°C with defined post-test limits for capacitance, tan δ and leakage current.
• Surface-Mount Chip Package — Radial, can-style SMD package engineered for high-density PCB layouts; case dimension L: 1.65 × D: 1.6 cm with recommended land size L: 1.63 × W: 1.63 cm.
• Ripple Current Ratings — Specified ripple current performance of 490 mA at 120 Hz and 735 mA at 10 kHz, enabling predictable AC performance across common frequencies.
• Regulatory Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronics — Surface-mounted on high-density PCBs where a bipolar aluminum electrolytic capacitor is required for general circuit use.
• Wide-temperature systems — Suitable for designs that must maintain capacitor performance across −55°C to +105°C.
• High-volume, automated production — Carrier-tape compatible for mounting by automatic assembly equipment.

Unique Advantages

• High capacitance in an SMD form — 470 µF in a chip radial-can package provides significant capacitance without large axial components.
• Reliable across a wide temperature span — Rated for −55°C to +105°C operation to support designs exposed to broad environmental conditions.
• Endurance-verified performance — 2000-hour endurance at 105°C with polarity inversion test procedures gives quantifiable lifecycle expectations.
• Assembly-friendly package — Designed for carrier-tape automated mounting to streamline PCB assembly processes.
• Defined ripple handling — Published ripple current values at 120 Hz and 10 kHz enable predictable thermal and AC behavior in system designs.
• RoHS compliant — Helps meet environmental regulatory requirements for finished products.
