UYA2A331MNS1MS

The UYA2A331MNS1MS is a chip-type aluminum electrolytic capacitor in Nichicon's UYA series designed for high-temperature, long-life applications. It provides 330 µF capacitance at a 100 V rating in a surface-mount, tape-fed radial can package suited for automated assembly.

Targeted use includes designs that require extended endurance at elevated temperatures and verified automotive-grade reliability—combining a high working voltage and substantial ripple current capability with AEC‑Q200 qualification and RoHS compliance.

Key Features

• Form factor & mounting — Chip-type radial can designed for surface-mount assembly; compatible with automatic mounting machines fed by carrier tape.
• Capacitance & voltage — 330 µF rated capacitance at 100 V with ±20% tolerance.
• Temperature range & endurance — Rated for operation from −40 °C to +125 °C with an extended load life of 5000 hours at +125 °C.
• Ripple current capability — 800 mA at 120 Hz and 1.6 A at 10 kHz to support power smoothing and filtering applications.
• Electrical characteristics — Leakage current specified as not more than 0.01CV or 3 µA (whichever is greater); tan δ max 0.1 at 100 V (measurement at 120 Hz, 20 °C).
• Reliability & compliance — AEC‑Q200 Qualified and RoHS directive compliant (2011/65/EU, (EU)2015/863).
• Compact dimensions — Package footprint L: 2.15 × D: 1.8 cm for space-efficient board designs.

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and high-temperature endurance make it suitable for vehicle electronic modules requiring long-life capacitors.
• Power Supply Filtering — 330 µF at 100 V with defined ripple current ratings for bulk filtering and decoupling in power rails.
• High‑Temperature Power Assemblies — Designed for equipment and subsystems that operate up to +125 °C and require stable capacitance over long duty cycles.
• Industrial Power Electronics — Applicable where elevated ambient temperatures and reliability expectations demand robust electrolytic components.

Unique Advantages

• Extended high‑temperature life: 5000 hours at +125 °C provides demonstrable endurance for demanding thermal environments.
• Automotive‑grade reliability: AEC‑Q200 qualification supports use in applications requiring standardized reliability assurance.
• Automated assembly ready: Chip form factor and carrier‑tape compatibility simplify pick‑and‑place integration and production throughput.
• High ripple acceptance: Specified ripple currents (800 mA @120 Hz, 1.6 A @10 kHz) allow effective smoothing in power conversion stages.
• Regulatory compliance: RoHS conformity meets environmental directive requirements for restricted substances.
• Space-conscious packaging: Compact 2.15 × 1.8 cm footprint helps conserve PCB area while delivering 330 µF at 100 V.
