UUR1E471MNL1GS

The UUR1E471MNL1GS is a chip-type aluminum electrolytic capacitor engineered for surface mounting on high-density printed circuit boards. It delivers high capacitance in a compact radial can SMD package and is compatible with automated assembly fed by carrier tape.

This part is RoHS compliant and AEC-Q200 rated for automotive applications. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance & Voltage — Nominal 470 µF capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage in compact SMD footprints.
• Compact SMD Package — Chip-type radial can SMD with dimensions L: 1 × D: 1 cm designed for high-density PCB placement and automated pick-and-place processes.
• Automated Assembly Compatible — Applicable to automatic mounting machines when supplied on carrier tape, easing integration into high-volume assembly lines.
• Automotive-Grade Reliability — AEC-Q200 compliant, supporting designs targeting automotive electronics where that qualification is required.
• Temperature & Endurance — Operating range −40°C to +85°C with endurance specified as 2000 hours at 85°C; capacitance change remains within ±20% after the endurance test.
• Ripple Current Capability — Rated ripple current of 393 mA at 120 Hz and 510.9 mA at 10 kHz for handling AC variations on power rails.
• Leakage Current Specification — Leakage current after 1 minute’s application of rated voltage at 20°C is not more than 0.03CV (µA), where C is rated capacitance (µF) and V is rated voltage (V).
• Low-Temperature Performance — Series-level impedance stability defined across temperatures, with specified Z(−25°C)/Z(+20°C) and Z(−40°C)/Z(+20°C) ratios for the rated voltage range.
• Environmental Compliance — Compliant to the RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Energy storage and decoupling in automotive control modules where AEC-Q200 compliance is required.
• High-Density PCB Assemblies — Bulk capacitance in compact footprints for densely populated boards, benefiting space-constrained designs.
• Automated Manufacturing — Suited for assemblies produced with automatic mounting machines using carrier tape.
• Power Management Subsystems — Filtering and smoothing on DC power rails where rated voltage and ripple current specifications match system needs.

Unique Advantages

• High Capacitance in a Small SMD Body: 470 µF in a 1 × 1 cm package reduces board area compared with larger through-hole capacitors.
• AEC-Q200 Rated: Provides the documented qualification required for many automotive electronic applications.
• Assembly-Friendly Design: Carrier-tape compatibility enables reliable feeding into automated pick-and-place equipment.
• Defined Endurance: 2000 hours at 85°C with controlled capacitance and leakage performance supports predictable long-term behavior in thermal stress conditions.
• Measurable Ripple Performance: Specific ripple current ratings at 120 Hz and 10 kHz help match the capacitor to switching and filtering applications.
• Regulatory Compliance: RoHS conformity aligns with regulatory requirements for restricted substances.

Why Choose UUR1E471MNL1GS?

UUR1E471MNL1GS combines high capacitance, automotive-grade qualification, and a compact SMD radial-can package to address power filtering and bulk energy needs on space-constrained PCBs. Its carrier-tape compatibility simplifies integration into automated production lines, and its defined ripple and endurance specifications make performance predictable under typical operating conditions.

This part is suited for existing automotive and industrial designs that require AEC-Q200 rated aluminum electrolytic capacitors. Because the product is scheduled for discontinuation and is not recommended for new designs, it is particularly relevant for maintenance, repair, and limited-production runs where direct part replacement is required.
