UYA2A331MNJ1MS

The UYA2A331MNJ1MS is a chip-type aluminum electrolytic capacitor in a radial can SMD package designed for board-level power applications. It offers 330 µF capacitance at a 100 V rating and is optimized for high-temperature, long-life operation.

Targeted for automotive and other demanding environments, this part combines extended load life (5,000 hours at +125°C), surface-mount compatibility with carrier-tape feeding, and industry-level reliability credentials for designs that require durable power filtering and energy storage.

Key Features

• Electrical Performance — 330 µF rated capacitance at 100 V with ±20% tolerance, providing bulk energy storage and smoothing for high-voltage rails.
• High Ripple Capability — Specified ripple currents of 800 mA at 120 Hz and 1.6 A at 10 kHz for handling varying load conditions and switching noise.
• Extended High‑Temperature Endurance — Rated for 5,000 hours at +125°C; endurance limits: capacitance change within ±30%, tan δ ≤ 300% of initial specified value, and leakage current within initial limits after the endurance test.
• Wide Operating Temperature Range — Operates from −40°C to +125°C, suitable for thermally demanding installations.
• Surface-Mount, Carrier-Tape Compatible — Chip-type SMD radial can designed for automatic mounting using carrier tape to support high-volume factory assembly.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting designs with regulated materials and automotive-grade reliability requirements.
• Leakage & Dissipation Characteristics — Leakage current specified as not more than 0.01CV or 3 µA (whichever is greater) after 2 minutes at 20°C; tan δ max. 0.1 at 100 V (measured at 120 Hz, 20°C).
• Robust Soldering Tolerance — Meets resistance-to-soldering-heat requirements: maintained characteristics after exposure to 250°C for 30 seconds on a hot plate.
• Compact Footprint — Case dimensions L: 2.15 cm × D: 1.8 cm with recommended land pattern L: 1.83 cm × W: 1.83 cm for PCB layout.

Typical Applications

• Automotive Electronics — Bulk decoupling and energy storage in automotive control modules and power circuits where AEC-Q200 qualification and high-temperature endurance are required.
• Power Conversion and Filtering — DC link, smoothing, and filtering in high-voltage power supplies and converters that require 100 V rating and high ripple current capability.
• High‑Temperature Industrial Electronics — Board-level energy storage and decoupling in industrial systems operating up to +125°C, benefiting from the extended 5,000‑hour life rating.

Unique Advantages

• Long High-Temperature Life: 5,000 hours at +125°C gives predictable endurance for designs exposed to sustained heat.
• Automotive-Grade Qualification: AEC-Q200 qualification supports use in demanding, reliability-focused applications.
• High Voltage and Bulk Capacitance: 100 V rating combined with 330 µF capacitance reduces the need for multiple components in high-voltage energy-storage roles.
• SMD Assembly Ready: Carrier-tape compatibility enables automated placement and efficient manufacturing for volume production.
• Measurable Electrical Limits: Specified leakage, tan δ, and ripple current figures allow predictable performance in power and filtering designs.
• RoHS Compliant: Conforms to environmental material standards for regulated markets.
