UYA1J241MNS1MS

The UYA1J241MNS1MS is a chip-type aluminum electrolytic capacitor from Nichicon’s UYA series designed for compact, high-temperature power applications. It delivers 240 μF at 63 V in a surface-mount can package engineered for automatic mounting (carrier-tape fed).

Key value comes from long-life high-temperature performance—rated for 5000 hours at +125°C—combined with automotive-grade qualification (AEC-Q200), RoHS compliance, and measurable ripple and leakage specifications suitable for power filtering and decoupling on space-constrained boards.

Key Features

• Capacitance & Voltage — 240 μF nominal capacitance with a 63 V rated voltage and ±20% tolerance for bulk energy storage and smoothing on medium-voltage rails.
• High-temperature Endurance — Extended load life of 5000 hours at +125°C; after endurance the capacitor meets defined limits for capacitance change (within ±30%), tan δ, and leakage current.
• AEC-Q200 Qualified — Qualified per AEC-Q200 for reliability in demanding environments.
• Surface-Mount, Tape-and-Reel Ready — Chip-type, can-style SMD package compatible with automatic mounting machines fed with carrier tape, enabling high-volume assembly.
• Thermal Range — Operating temperature from −40°C to +125°C to support high-temperature system designs.
• Ripple Current Capability — Specified ripple handling of 325 mA at 120 Hz and 650 mA at 10 kHz for effective filtering under load.
• Low Leakage — Leakage current specified as not more than 0.01CV or 3 μA (whichever is greater) after 2 minutes at 20°C, supporting low-standby-loss designs.
• Electrical Stability — tan δ ≤ 0.12 at 63 V (measured at 120 Hz, 20°C) and defined low-temperature impedance behavior (impedance ratio up to 7 at −40°C vs +20°C for the 63 V rating).
• Package & Footprint — Compact dimensions L: 1.35 × D: 1.25 cm with surface-mount can construction; height seated max 1.35 cm for space-limited layouts.
• Manufacturing Robustness — Resistance to soldering heat test: 30 s on a 250°C hot plate with capacitance change within ±10% and no increase in tan δ or leakage beyond initial specified values.
• Environmental Compliance — RoHS compliant per the listed directives.

Typical Applications

• Automotive Electronic Modules — Engine control, body electronics, and power distribution modules where AEC-Q200 qualification and extended high-temperature life are required.
• Power Supply Bulk Filtering — Bulk smoothing and hold-up for medium-voltage rails in DC-DC converters and onboard power supplies, leveraging the 240 μF capacitance and specified ripple ratings.
• Power Rail Decoupling — Local decoupling for regulators and power stages in compact, high-density PCBs where surface-mount can packaging and carrier-tape assembly are beneficial.
• Industrial Electronics — High-temperature industrial control and power-management systems needing long-life capacitors capable of sustained operation at elevated temperatures.

Unique Advantages

• Long High‑Temperature Life: 5000 hours at +125°C provides predictable lifetime behavior for designs exposed to sustained high temperatures.
• Automated Assembly Ready: Chip-type SMD format and carrier-tape compatibility reduce assembly complexity and support high-volume pick-and-place processes.
• Automotive-Grade Reliability: AEC-Q200 qualification signals suitability for demanding, reliability-focused applications.
• Compact High Capacitance: 240 μF in a small L:1.35 × D:1.25 cm package helps minimize board area while maintaining energy storage capacity.
• Measured Ripple & Leakage Performance: Defined ripple current ratings (325 mA @120 Hz, 650 mA @10 kHz) and low leakage specification enable confident use in power filtering tasks.
• Process-Proven Robustness: Soldering-heat and shelf-life test criteria from the datasheet demonstrate tolerance to manufacturing and storage stressors.
