UYA1J431MNS1MS

The UYA1J431MNS1MS is a chip‑type aluminum electrolytic capacitor from Nichicon's UYA series, offering 430 µF capacitance at a 63 V rating in a surface‑mount radial can package. It is designed for automated assembly (carrier tape fed) and is RoHS compliant with AEC‑Q200 qualification for automotive use.

With an extended load life of 5000 hours at +125°C and an operating temperature range of −40°C to +125°C, this part targets high‑temperature, long‑life applications where high capacitance in an SMD form factor is required.

Key Features

• Electrical Specification — 430 µF nominal capacitance at 63 V with ±20% tolerance; designed to provide bulk capacitance in compact SMD assemblies.
• High‑temperature Endurance — Extended load life: 5000 hours at +125°C; endurance criteria include capacitance change within ±30% and leakage current within initial specified limits after test.
• Automotive Qualification — AEC‑Q200 qualified, supporting automotive electronics requirements for component reliability and performance.
• Operating Range — Rated for −40°C to +125°C operation, suitable for elevated temperature environments commonly found in automotive and industrial installations.
• Low Leakage and Loss Characteristics — Leakage current specification: after 2 minutes at rated voltage and 20°C, not more than 0.01CV or 3 µA (whichever is greater); tan δ (63 V) max 0.12 at 120 Hz, 20°C.
• Ripple Current Performance — Ripple current ratings of 465 mA at 120 Hz and 930 mA at 10 kHz provide thermal/ripple handling guidance for power applications.
• Surface‑Mount, Tape‑Feed Compatibility — Chip type packaged for automatic mounting machines fed with carrier tape, enabling high‑volume assembly processes.
• Compact SMD Can — Size footprint L: 1.65 × D: 1.6 cm for integration where board space and high capacitance are both required.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suited for electronic modules and control units that require components qualified to AEC‑Q200 and capable of long life at elevated temperatures.
• High‑Temperature Systems — Intended for assemblies operating up to +125°C where extended load life and stable capacitance are required.
• Compact Power Modules — Provides high bulk capacitance in an SMD radial can, useful where board space is constrained but high energy storage is needed.

Unique Advantages

• Long, defined high‑temperature life — 5000 hours at +125°C gives designers a clear endurance metric for thermal stress planning.
• AEC‑Q200 qualification — Facilitates selection for automotive programs by meeting recognized reliability standards for vehicular electronics.
• SMD compatibility for automated assembly — Carrier‑tape feedable chip package simplifies integration into high‑volume manufacturing flows.
• High capacitance in a compact footprint — 430 µF at 63 V in a 1.65 × 1.6 cm package helps reduce BOM count when high capacitance is needed on constrained PCBs.
• Measured electrical characteristics — Specified leakage, tan δ, and ripple current values allow predictable performance modeling in power and energy storage designs.
• RoHS compliance — Meets current RoHS directives for regulatory and market requirements.
