UCX1A331MCL1GS

The UCX1A331MCL1GS is a chip-type aluminum electrolytic capacitor in a surface-mount radial can designed for high-temperature operation. It combines a 330 µF capacitance at 10 V with a compact 1 × 1 cm package and is compatible with automatic mounting using carrier tape.

Targeted primarily at automotive and other high-temperature electronics, this part delivers measured ESR data, specified ripple capability, and long-term endurance to support designs that require stable power filtering and decoupling under elevated temperature conditions.

Key Features

• Capacitance & Voltage: 330 µF capacitance rated for 10 V DC with ±20% tolerance (120 Hz, 20°C).
• Temperature Range: Rated for operation from −40°C to +135°C.
• AEC-Q200 Qualified: Series-qualified to AEC-Q200 for automotive-grade deployment.
• High-Temperature Endurance: Designed for 2000 hours at 135°C with post-test performance criteria for capacitance, tan δ and leakage current.
• Low-Temperature ESR Specification: ESR specified at 150 mΩ (measured at 100 kHz); datasheet includes ESR verification after −40°C testing.
• Ripple Current Ratings: 250 mA at 120 Hz and 500 mA at 10 kHz to support smoothing and decoupling tasks.
• Surface-Mount, Assembly Ready: Radial, can-style SMD construction compatible with carrier-tape feeding for automatic placement.
• Regulatory Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).
• Compact Footprint: Body dimension 1 × 1 cm with recommended land size 1.03 × 1.03 cm for PCB layout.

Typical Applications

• Automotive Electronics: Power filtering and decoupling in control modules where AEC-Q200 qualification and operation up to 135°C are required.
• High-Temperature Electronics Assemblies: Surface-mount applications that use automatic placement with carrier-tape and need components rated for elevated operating temperatures.
• Power Supply Smoothing: Local bulk capacitance and ripple smoothing in compact, board-mounted power stages that require defined ripple current handling.

Unique Advantages

• High-temperature reliability: Proven endurance of 2000 hours at 135°C provides predictable life under sustained thermal stress.
• Automotive-grade qualification: AEC-Q200 status supports use in automotive systems and related high-reliability markets.
• Characterized ESR across temperature: ESR specified at 150 mΩ (100 kHz) and verified after −40°C testing for predictable performance across the rated temperature range.
• Assembly-friendly SMD format: Radial can SMD and carrier-tape compatibility simplify automated PCB assembly for volume production.
• Measured ripple capability: Clear ripple current ratings at both low and high frequencies (120 Hz and 10 kHz) enable confident selection for filtering tasks.
• Regulatory readiness: RoHS compliance reduces environmental and regulatory integration work for end products.
