UWT1A102MNL1GS

The UWT1A102MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UWT series designed for surface mounting on high-density PCBs. It provides 1 mF capacitance at a 10 V rating in a compact SMD radial-can package.

Engineered for demanding environments, this part supports a wide operating temperature range (−55 to +105°C), is AEC-Q200 qualified for automotive applications, and is RoHS compliant. It is suitable for automated assembly and long-life deployments where thermal and vibration resilience are required.

Key Features

• Capacitance & Voltage — 1 mF capacitance rated at 10 V with a tolerance of ±20% at 120 Hz, 20°C, providing bulk energy storage for decoupling and filtering.
• Wide Temperature Range — Specified for operation from −55°C to +105°C to support high- and low-temperature environments.
• Automotive Qualification — AEC-Q200 qualified, making it appropriate for automotive electronic designs that require recognized component-level reliability.
• Endurance & Lifetime — Rated for 1000 hours at 105°C; after endurance testing, capacitance remains within ±25% (for 16 V or less ratings) and leakage current remains at or below initial specified values.
• Ripple Current Performance — Handles 310 mA at 120 Hz and 465 mA at 10 kHz, enabling effective filtering of low- and high-frequency ripple components.
• Low-Temperature Impedance Stability — Impedance ratios for the 10 V rating: Z(−25°C)/Z(+20°C) = 3 and Z(−40°C)/Z(+20°C) = 8, useful for cold-start and low-temperature operation analysis.
• Soldering and Assembly — Designed for surface mounting on high-density PC boards and compatible with automatic mounting machines fed by carrier tape; marked with black print on the case top for orientation and identification.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Leakage and Dissipation — Leakage current after 2 minutes at 20°C is ≤ 0.01CV or 3 µA (whichever is greater); tangent of loss angle (tan δ) at 120 Hz for 10 V is specified at 0.24 (max.).

Typical Applications

• Automotive Electronics — Bulk and decoupling capacitance in control modules and sensor interfaces where AEC-Q200 qualification and wide temperature operation are required.
• Power Supply Filtering — Smoothing and ripple reduction for DC/DC converters and voltage regulators, leveraging the specified ripple current ratings at both 120 Hz and 10 kHz.
• High-Density PCB Designs — Compact SMD radial-can package tailored for space-constrained boards and automated placement processes.
• Backup and Hold-Up Circuits — Energy storage for short-term hold-up or local energy buffering in systems exposed to temperature extremes.

Unique Advantages

• Wide operating temperature span: −55°C to +105°C supports designs that must operate across harsh thermal environments without additional thermal mitigation.
• Automotive-grade qualification: AEC-Q200 status provides documented component reliability for automotive system designers and suppliers.
• Compact SMD radial-can form factor: Small 1 cm × 1 cm footprint and defined land pattern (1.03 × 1.03 cm) simplify integration on high-density PCBs while enabling automated assembly.
• Long-term high-temperature endurance: Rated 1000 hours at 105°C with controlled capacitance and leakage characteristics for predictable life-cycle performance.
• Dual-frequency ripple handling: Specified ripple current at both 120 Hz and 10 kHz supports filtering across a range of switching and line-frequency conditions.
• Regulatory conformity: RoHS compliance streamlines regulatory acceptance and supply-chain management for commercial and automotive programs.
