UUN1E471MNQ1MS

The UUN1E471MNQ1MS is a chip-type, bi-polarized aluminum electrolytic capacitor in the Nichicon UUN series, offering 470 µF capacitance at a 25 V rating. It is engineered for surface mounting on high-density printed circuit boards and is compatible with automated assembly fed by carrier tape.

This part provides higher capacitance in a compact SMD can-style package with a wide operating temperature range from −55 °C to +105 °C and an endurance rating of 2000 hours at 105 °C, making it suitable for a variety of general-purpose electronic designs that require reliable bipolar operation and robust ripple handling.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, specified at 120 Hz, 20 °C.
• Bi-polarized Construction: Bi-polar design enables operation where polarity may invert during use, per the UUN series specification.
• Wide Temperature Range: Specified operation from −55 °C to +105 °C to support designs exposed to broad ambient conditions.
• Endurance & Reliability: Endurance verified with 2000 hours at 105 °C (with polarity inversion every 250 hours), with capacitance change within ±20% and leakage current within initial specified limits after the test.
• Ripple Current Performance: Rated ripple currents of 490 mA at 120 Hz and 735 mA at 10 kHz to support AC and filtering applications requiring stable ripple handling.
• Surface-Mount Package: Chip-style radial can SMD package designed for high-density PCBs; compatible with automatic mounting machines using carrier tape. Surface-mount land size: 1.63 × 1.63 cm.
• Leakage and Dissipation: Leakage current defined by the series specification (I ≤ 0.03 C V µA after 1 minute at 20 °C) and tangent of loss angle (tan δ) limits per rated voltage.

Typical Applications

• General-purpose electronic circuits: Provides high capacitance and bipolar operation for filtering and decoupling in a broad range of consumer and industrial equipment identified as general purpose.
• High-density surface-mount assemblies: Chip-type SMD can package is intended for surface mounting on high-density PC boards and automated assembly processes.
• Equipment exposed to wide temperature ranges: Suitable for designs that require stable performance from −55 °C to +105 °C and verified endurance at elevated temperatures.
• Volume manufacturing: Compatible with automatic mounting machines fed by carrier tape, aiding automated assembly flows and consistent placement.

Unique Advantages

• High capacitance in SMD form: 470 µF in a chip-type can enables higher energy storage without resorting to through-hole parts, simplifying board layout for dense designs.
• Bipolar capability: Eliminates polarity restrictions for applications where voltage may reverse, expanding usability across circuit topologies.
• Wide operating range and proven endurance: −55 °C to +105 °C rating and 2000-hour endurance at 105 °C support robust long-term operation in challenging environments.
• Measured ripple handling: Specified ripple current values at 120 Hz and 10 kHz provide designers with quantifiable performance for AC and filtering use cases.
• Automated assembly-ready: Designed for carrier-tape feeding to support high-volume SMT production and consistent board assembly.
