UCM1E821MNL1GS

The UCM1E821MNL1GS is a chip-type aluminum electrolytic capacitor engineered for surface-mount assembly with a low-impedance design. It delivers 820 µF capacitance at a 25 V rating and is intended for demanding thermal and ripple environments.

Designed for automotive applications and other high-reliability markets, this Nichicon UCM series part combines low leakage, high ripple-current capability, and AEC-Q200 qualification with RoHS compliance to support automated production and long-term field performance.

Key Features

• Capacitance & Voltage  820 µF capacitance rated at 25 V with ±20% tolerance for bulk energy storage and supply stabilization.
• Low-Impedance Performance  Chip-type, low-impedance construction optimized for reduced AC voltage variation and improved filtering performance.
• High Ripple Current Handling  Specified ripple capability of 595 mA at 120 Hz and 1.19 A at 10 kHz to support switching and high-frequency loads.
• Leakage Current  Low leakage current characteristic of 205 µA, supporting energy-efficient standby and lower quiescent loss.
• Thermal Endurance  Rated for operation from −55°C to +105°C with an endurance life of 2000 hours at 105°C.
• Package & Assembly  Radial can, chip-style SMD package supplied in embossed carrier taping for compatibility with automated pick-and-place assembly.
• Automotive-Grade Qualification & Compliance  AEC-Q200 qualified and RoHS compliant, suitable for automotive electronics where those qualifications are required.

Typical Applications

• Automotive Power Modules  Bulk smoothing and energy buffering where 25 V rating, high ripple-current capability, and 105°C endurance are required.
• Electronic Control Units (ECUs)  Power supply decoupling and filtering in control units benefitting from AEC-Q200 qualification and low leakage.
• Infotainment and Body Electronics  Supply stabilization and ripple suppression in compact SMD assemblies enabled by chip-type packaging and embossed carrier taping.

Unique Advantages

• High Capacitance in a Chip Form  820 µF capacitance in a chip-style SMD package provides substantial bulk storage while supporting automated assembly.
• Robust Ripple Handling  Dual-frequency ripple specifications (595 mA at 120 Hz, 1.19 A at 10 kHz) address both low- and high-frequency noise sources.
• Wide Temperature Range and Endurance  −55°C to +105°C operating range and 2000-hour life at 105°C enable reliable operation in thermally demanding environments.
• Automotive Qualification  AEC-Q200 qualification provides an established reliability baseline for automotive electronics designs.
• Manufacturing-Ready Packaging  Embossed carrier taping and SMD can format streamline integration into automated production workflows.
• Regulatory Compliance  RoHS-compliant construction supports regulatory and environmental requirements.
