UCM1E821MNS1GS

The UCM1E821MNS1GS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly. It delivers 820 µF of capacitance at a 25 V rating with low impedance characteristics and packaging suited for automated placement.

Engineered for demanding environments, this part supports a wide operating temperature range from −55°C to +105°C, AEC‑Q200 qualification, vibration resistance, and embossed carrier taping for high-volume manufacturing. Typical use cases include power filtering and bulk decoupling in automotive and industrial power systems where high capacitance, ripple handling and reliability are required.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage and smoothing on DC rails.
• Low Impedance Chip Type — Designed as a low-impedance surface-mount aluminum electrolytic to support effective ripple suppression and transient response in power circuits.
• Ripple Current Performance — Low-frequency ripple current of 595 mA (120 Hz) and high-frequency ripple current of 1.19 A (10 kHz), enabling reliable operation under AC ripple and switching converter loads.
• Leakage Current — Specified leakage current of 205 µA for predictable standby and idle current behavior.
• Temperature & Endurance — Operating range −55°C to +105°C with a life rating of 2000 hours at 105°C (endurance specified for this size class), supporting long-term thermal reliability.
• Automotive Qualification & Compliance — AEC‑Q200 rated and RoHS compliant, suitable for qualified automotive and industrial designs.
• Package & Assembly — φ10 × 10L can-style SMD package with vibration resistance and supplied in embossed carrier taping for automated surface-mount assembly; recommended land size 1.03 × 1.03 cm.

Typical Applications

• Automotive power modules — Bulk smoothing and decoupling on DC rails within electronic control units and power distribution modules where AEC‑Q200 qualification and thermal endurance are required.
• DC-DC converters — Output filtering and energy buffering for converters operating with high ripple currents and fast transient loads.
• Power supply filtering — Bulk capacitance for smoothing rectified supplies and reducing voltage ripple in industrial and vehicular systems.

Unique Advantages

• High capacitance in a compact SMD can — 820 µF in a φ10 × 10 mm package provides significant bulk energy storage while enabling surface-mount assembly.
• Measurable ripple-handling capability — Specified low- and high-frequency ripple currents (595 mA @120 Hz, 1.19 A @10 kHz) give designers quantifiable margins for converter and filter designs.
• Automotive-grade reliability — AEC‑Q200 qualification and vibration resistance address automotive and harsh-environment durability requirements.
• Wide temperature and endurance rating — −55°C to +105°C operation and 2000 hours endurance at 105°C for sustained thermal performance in demanding applications.
• Automated assembly ready — Embossed carrier taping and a standard SMD can package simplify high-volume pick-and-place processes and improve manufacturing throughput.
• Regulatory compliance — RoHS compliant for environmentally conscious designs.
