UWT1A681MNL1GS

The UWT1A681MNL1GS is a chip-type aluminum electrolytic capacitor from the Nichicon UWT series, specified for surface-mount assembly on high-density PC boards. Its design and qualification target demanding environments: the part operates across a wide temperature range (−55°C to +105°C) and is AEC‑Q200 qualified for automotive use while meeting RoHS requirements.

This 680 µF, 10 V polarized capacitor delivers high capacitance in a compact SMD can package (L × D: 1 cm × 1 cm) and is compatible with carrier-tape automated mounting, supporting efficient production for automotive and other high-reliability electronics.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 10 V with tolerance ±20% (at 120 Hz, 20°C), providing substantial bulk capacitance for decoupling and energy storage in compact circuits.
• Wide Temperature Range — Specified operation from −55°C to +105°C, supporting electronics that must function across extreme ambient conditions.
• AEC‑Q200 Qualified & RoHS Compliant — AEC‑Q200 qualification and compliance with RoHS (2011/65/EU, (EU)2015/863) support automotive and regulated applications.
• Endurance — Designed to meet endurance requirements after 1000 hours at 105°C per the series specification, providing predictable long-term performance under elevated temperature stress.
• Ripple Current Ratings — Rated ripple current of 310 mA at 120 Hz and 465 mA at 10 kHz, enabling AC filtering and smoothing across low and high frequency ranges.
• Surface-Mount, Tape-Fed Packaging — Radial SMD can package engineered for high-density PCB placement and compatibility with automatic mounting machines fed by carrier tape.
• Leakage Current — After 2 minutes at rated voltage and 20°C, leakage is specified as not more than 0.01CV or 3 µA (whichever is greater), per the series datasheet.

Typical Applications

• Automotive Electronics — Suited for vehicle electronic modules where AEC‑Q200 qualification and extended temperature range are required.
• High-Density Surface-Mount Assemblies — Compact SMD can package supports space-constrained PCBs in power management and control boards.
• Automated Production Lines — Carrier-tape compatible packaging enables efficient placement with automatic mounting machines for volume manufacturing.

Unique Advantages

• High Capacitance in a Compact Footprint: 680 µF in a 1 cm × 1 cm package offers significant bulk capacitance where board area is limited.
• Wide Operating Temperature: −55°C to +105°C range ensures stable electrical performance across harsh environments.
• Automotive-Grade Qualification: AEC‑Q200 qualification supports use in automotive systems that require controlled component-level reliability.
• Manufacturing Efficiency: Designed for surface-mount placement and tape-fed automatic assembly to reduce handling and speed production.
• Verified Endurance: Endurance specified for 1000 hours at 105°C provides predictable long-term behavior under thermal stress.
• Dual-Frequency Ripple Ratings: Specified ripple current at both 120 Hz and 10 kHz supports filtering across common power and switching frequencies.
