UYA1K271MNJ1MS

The UYA1K271MNJ1MS is a chip-type aluminum electrolytic capacitor engineered for long-life operation at elevated temperatures. It combines a 270 µF capacitance with an 80 V rating in a surface-mount radial can package designed for carrier-tape mounting and automated assembly.

Targeted at applications that require high-temperature endurance and robust performance, this part is AEC-Q200 qualified and RoHS compliant, offering defined electrical characteristics and ripple handling across a wide operating temperature range.

Key Features

• Capacitance & Voltage — Rated at 270 µF with an 80 V nominal voltage and a tolerance of ±20% (at 120 Hz, 20 °C).
• High-temperature Endurance — Extended load life specification of 5000 hours at +125 °C; after this endurance test capacitance remains within ±30%, tan δ ≤ 300% of initial specified value, and leakage current meets initial limits.
• Operating Temperature Range — Specified for −40 °C to +125 °C to support high-temperature environments.
• Ripple Current Performance — Rated ripple current of 465 mA at 120 Hz and 930 mA at 10 kHz for AC filtering and smoothing under load.
• Leakage Current — After 2 minutes at 20 °C, leakage current is specified as not more than 0.01CV or 3 µA, whichever is greater.
• Package & Mounting — Chip-type radial can for surface-mount placement; compatible with carrier-tape feeding for automatic mounting. Size: L 1.65 × D 1.6 cm; surface-mount land size: 1.63 × 1.63 cm.
• Soldering Heat Resistance — Meets soldering heat requirements after 30 s on a 250 °C hot plate with capacitance change within ±10% and electrical characteristics maintained.
• Quality & Compliance — AEC-Q200 qualified and compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power systems — Suited for in-vehicle power electronics where AEC-Q200 qualification and long life at +125 °C are required.
• High-temperature electronics — Provides bulk capacitance and ripple handling in modules that operate across −40 °C to +125 °C.
• Surface-mount assemblies — Designed for automated production lines with carrier-tape compatibility for efficient placement.

Unique Advantages

• Long life at elevated temperature — 5000 hours endurance at +125 °C reduces replacement frequency and supports thermal reliability targets.
• AEC-Q200 qualification — Enables use in applications that require validated performance for automotive-grade components.
• Compact chip SMD format — Delivers 270 µF capacitance in a surface-mount radial can, simplifying board layout compared with larger discrete solutions.
• High ripple capability — Specified ripple currents at 120 Hz and 10 kHz support effective smoothing in power circuits.
• Manufacturing-ready — Carrier-tape compatible for automated placement and meets soldering heat resistance criteria for surface-mount assembly.
• Regulatory compliance — RoHS conformity for global environmental requirements.
