UYA2A241MNJ1MS

The UYA2A241MNJ1MS is a Nichicon UYA series chip-type aluminum electrolytic capacitor optimized for long-life operation in high-temperature environments. As a polarized, surface-mount (radial can – SMD) device, it is designed for automated placement via carrier tape and intended for applications that require stable bulk capacitance at elevated temperatures.

Key value propositions include extended load life at +125°C, AEC-Q200 qualification for automotive use, and RoHS compliance, making this part suitable for demanding power and control systems where temperature resilience and durability are required.

Key Features

• Electrical Performance — 240 µF capacitance at a 100 V rating with ±20% tolerance, providing reliable bulk energy storage for power rails and decoupling.
• High-Temperature Endurance — Extended load life of 5000 hours at +125°C; after endurance testing the capacitance change remains within ±30% and leakage current meets initial specified limits.
• Ripple Current Capability — Rated ripple current of 750 mA at 120 Hz and 1.5 A at 10 kHz, supporting both low- and high-frequency ripple filtering in power systems.
• Wide Operating Range — Operating temperature range from −40°C to +125°C; impedance stability at low temperature is specified (impedance ratio max 3 at −40°C for 100 V rating).
• Manufacturing and Mounting — Chip-type SMD in a radial can package suitable for automatic mounting machines fed with carrier tape; recommended surface-mount land size 1.63 × 1.63 cm.
• Reliability & Standards — AEC-Q200 qualified and RoHS compliant; leakage current specification: after 2 minutes at rated voltage and 20°C leakage ≤ 0.01CV or 3 µA (whichever is greater).

Typical Applications

• Automotive Electronics — Bulk smoothing and energy storage in electronic control units and power modules, leveraging AEC-Q200 qualification and 125°C endurance.
• Power Conversion — Input/output filtering and ripple suppression in DC–DC converters and power supply modules, supported by specified ripple current ratings at 120 Hz and 10 kHz.
• Industrial Power Systems — High-temperature power electronics and motor drives where long life at elevated temperatures is required.
• Embedded Control and Power Management — Bulk decoupling in controllers and power management boards that require a polarized high-voltage SMD capacitor with robust thermal performance.

Unique Advantages

• Long High-Temperature Life: 5000-hour endurance at +125°C ensures continued capacitance and controlled leakage after extended high-temperature operation.
• Automotive-Grade Qualification: AEC-Q200 rating supports use in automotive electronics and other reliability-driven designs.
• Broad Frequency Ripple Support: Specified ripple current at both low and high frequencies (750 mA @120 Hz, 1.5 A @10 kHz) allows flexible use across switching and linear power stages.
• Automated Assembly Ready: Chip-type SMD format and carrier-tape compatibility streamline high-volume SMT processes.
• Defined Leakage and Dissipation: Clear leakage current formula and tan δ limits (tan δ max 0.1 at 100 V) provide measurable parameters for design verification.
