UWT1C681MNL1GS

The UWT1C681MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UWT series, specified at 680 µF and 16 V. It is designed for surface mounting on high-density PC boards and is compatible with automatic carrier-tape mounting.

Engineered for wide temperature operation from −55 °C to +105 °C and qualified to AEC-Q200, this capacitor suits demanding environments where robust capacitance, reliable endurance, and compact SMD packaging are required.

Key Features

• Core Electrical Performance — 680 µF capacitance at 16 V with ±20% tolerance, providing bulk capacitance for decoupling and energy storage in compact assemblies.
• Wide Temperature Range — Rated for −55 °C to +105 °C, enabling stable operation across extended ambient and thermal conditions.
• Reliability & Endurance — AEC-Q200 qualified; endurance specified as 1000 hours at 105 °C with capacitance change within ±25% for 16 V or less after the endurance test.
• Leakage and Loss Characteristics — Leakage current guaranteed to be no more than 0.01CV or 3 µA (whichever is greater) after 2 minutes at 20 °C; tan δ (loss angle) max 0.20 at 16 V (measured at 120 Hz, 20 °C).
• Ripple Current Ratings — Supports 310 mA at 120 Hz and 465 mA at 10 kHz, suitable for smoothing and ripple handling on power rails.
• SMD Can Package — Radial, can-style SMD package (L × D: 1.0 × 1.0 cm) designed for surface-mount assembly; surface mount land size 1.03 × 1.03 cm.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.

Typical Applications

• Automotive Power Filtering — Bulk smoothing and decoupling on automotive control modules and power rails, leveraging AEC-Q200 qualification and wide temperature capability.
• DC–DC Converter Output — Output filter capacitance for buck/boost converters where compact SMD packaging and specified ripple current capability are required.
• Embedded Power Supplies — Energy storage and transient buffering on high-density PCBs in industrial and transportation electronics.

Unique Advantages

• AEC-Q200 Qualification: Provides explicit suitability for automotive and other reliability-focused designs that require industry-recognized component qualification.
• Wide Operating Temperature: −55 °C to +105 °C rating ensures consistent capacitance and impedance behavior across harsh thermal environments.
• High Bulk Capacitance in SMD: 680 µF in a 1.0 × 1.0 cm can-style SMD reduces board area compared with equivalent through-hole parts while enabling automated pick-and-place assembly.
• Defined Endurance: 1000 hours at 105 °C with specified limits on capacitance change and leakage current gives clear lifecycle expectations for design validation.
• Measured Ripple Performance: Published ripple current values at 120 Hz and 10 kHz allow designers to match capacitor selection to converter switching frequencies and thermal budgets.
• Regulatory Compliance: RoHS conformity supports use in products requiring restricted-substance compliance.
