UYA1K431MNS1MS

The UYA1K431MNS1MS is a chip‑type aluminum electrolytic capacitor designed for surface‑mount assemblies and automated production. It delivers 430 µF at 80 V in a radial can SMD package and is designed for long life under elevated temperature conditions.

Targeted at automotive and other high‑reliability markets, this part combines extended load life, AEC‑Q200 qualification, and RoHS compliance to support demanding electronic systems that require sustained performance up to +125°C.

Key Features

• Capacitance and Voltage — 430 µF rated capacitance at 80 V, with tolerance of −20% to +20%.
• Extended High‑Temperature Life — Endurance rating of 5000 hours at +125°C, with capacitance change within ±30% after the endurance test.
• AEC‑Q200 Qualified — Series‑level qualification for applications requiring automotive‑grade component reliability.
• Wide Operating Temperature — Specified operating range from −40°C to +125°C to support harsh environment operation.
• Surface‑Mount, Carrier‑Tape Ready — Chip‑type SMD can package designed for automatic mounting machines fed with carrier tape.
• Leakage and Dissipation Parameters — Leakage current after 2 minutes is ≤ 0.01CV or 3 µA (whichever is greater); tan δ for 80 V parts is specified at 0.12 (120 Hz, 20°C).
• Ripple Current Capability — Rated ripple current of 750 mA at 120 Hz and 1.5 A at 10 kHz for handling AC stress in power circuits.
• Compact Chip‑Type Dimensions — Package footprint with dimensions L: 2.15 × D: 1.6 cm in a radial, can‑style SMD format.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suitable for automotive systems that require AEC‑Q200 qualified passives and long high‑temperature life.
• Surface‑Mount Power Modules — Designed for SMD assemblies and automatic mounting via carrier tape for high‑volume production.
• High‑Temperature Electronic Systems — Specified for operation and endurance at temperatures up to +125°C.

Unique Advantages

• Long Thermal Endurance: 5000 hours at +125°C provides predictable aging and performance over extended high‑temperature exposure.
• Automated Assembly Ready: Chip‑type SMD can packaged for carrier‑tape feeding supports streamlined high‑volume PCB assembly.
• Automotive‑Grade Reliability: AEC‑Q200 qualification aligns the component with automotive reliability requirements.
• High Capacitance Density: 430 µF in a compact radial can SMD footprint supports bulk energy storage in tight PCB real estate.
• Measured Leakage and Dissipation: Defined leakage current and tan δ values provide clear electrical limits for design validation.
• Regulatory Compliance: RoHS conformity supports environmental and regulatory needs in product development.
