UCM1E471MNS1GS

The UCM1E471MNS1GS is a chip-type, low-impedance aluminum electrolytic capacitor in a surface-mount can package. It delivers 470 µF capacitance at a 25 V rating with a compact φ8 × 10 mm footprint and embossed carrier taping for automatic mounting.

Designed for demanding electronic modules, this capacitor combines high capacitance density, measurable low loss (tan δ = 0.14 at 20°C, 120 Hz) and defined ripple handling for applications that require robust decoupling and energy buffering across a wide operating temperature range.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with ±20% tolerance, rated for 25 V operation.
• Low Loss / Low Impedance — Tangent of loss angle (tan δ) of 0.14 measured at 20°C, 120 Hz, supporting efficient filtering and lower heat generation in AC conditions.
• Ripple Current Capability — Specified ripple performance of 425 mA at 120 Hz and 850 mA at 10 kHz, enabling both low- and high-frequency smoothing duties.
• Leakage Current — Maximum leakage consistent with 0.01·C·V formula (117.5 µA), suitable for power-electronics designs requiring predictable standby current.
• Temperature & Endurance — Rated for operation from −55°C to +105°C with endurance specified at 2000 hours at 105°C.
• Package & Mounting — Surface-mount radial can (φ8 × 10 mm) supplied on embossed carrier tape for automatic placement; recommended SMD land size 8.3 × 8.3 mm.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant; vibration resistant construction for use in mechanically demanding environments.

Typical Applications

• Automotive electronic modules — Energy buffering and ripple filtering in 25 V circuits where AEC-Q200 qualification and wide temperature range are required.
• Power conversion and regulation — Bulk decoupling and smoothing where 470 µF and defined ripple ratings (425 mA @120 Hz, 850 mA @10 kHz) improve regulator stability.
• Harsh-environment electronics — Vibration-resistant construction and −55°C to +105°C operation for equipment exposed to mechanical stress and wide thermal swings.
• Automated assembly lines — Embossed carrier taping and chip-type SMD can package enable efficient pick-and-place mounting on high-volume production lines.

Unique Advantages

• AEC-Q200 Qualification: Provides a traceable qualification level for automotive and other high-reliability applications, supporting design confidence under industry stress requirements.
• High Capacitance in a Compact SMD Can: 470 µF in a φ8 × 10 mm package delivers substantial bulk capacitance where board space is limited.
• Defined Low-Frequency and High-Frequency Ripple Ratings: Specified ripple currents at 120 Hz and 10 kHz enable predictable filtering performance across a range of switching and line-frequency conditions.
• Wide Temperature & Endurance Specified: −55°C to +105°C operation with 2000 hours endurance at 105°C provides long-term stability for thermal and mission-critical designs.
• Assembly-Friendly Packaging: Embossed carrier taping and recommended land pattern streamline automated placement and consistent soldering performance.
• Predictable Leakage Behavior: Leakage current defined by 0.01·C·V (117.5 µA for this part) helps designers budget standby and fault currents accurately.
