UCX1A471MCL1GS

The UCX1A471MCL1GS is a chip‑type aluminum electrolytic capacitor engineered for high‑temperature operation up to +135°C. It delivers 470 µF capacitance at 10 V in a compact surface‑mount can package designed for automated pick‑and‑place via carrier tape.

Targeted at designs that require high temperature endurance and controlled ESR across temperature extremes, the part is AEC‑Q200 qualified and RoHS compliant, with ESR specified after low‑temperature (-40°C) testing to support reliable performance across the full −40°C to +135°C range.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance for bulk energy buffering and decoupling.
• High Temperature Qualification — Rated for operation from −40°C to +135°C and endurance of 2000 hours at 135°C, supporting prolonged high‑temperature deployment.
• Low‑temperature ESR Specification — ESR defined at 150 mΩ (measured at 100 kHz) and verified after −40°C testing to ensure predictable behavior in cold start and low‑temperature conditions.
• Ripple Current Capability — Rated ripple currents of 250 mA at 120 Hz and 500 mA at 10 kHz for AC stress and switching applications.
• Surface‑mount Can Package — Radial can SMD chip (L × D: 1 × 1 cm) optimized for automated mounting; recommended land size 1.03 × 1.03 cm.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant; suitable for designs requiring documented automotive‑grade reliability metrics.
• Polarized Electrolytic — Polar construction for use in DC bulk, filtering, and energy storage circuits.

Typical Applications

• Automotive Electronics — Bulk filtering, decoupling and energy storage in modules where AEC‑Q200 qualification and 135°C endurance are required.
• Power Conversion — Output smoothing and ripple suppression for DC‑DC converters and voltage regulators exposed to elevated operating temperatures.
• Control & Sensor Modules — Local energy reservoir and transient handling in engine control units, sensor front‑ends, and power management boards.
• High‑Temperature Embedded Systems — Systems with elevated ambient or board temperatures that need long life (2000 h at 135°C) and defined low‑temperature ESR behavior.

Unique Advantages

• High‑temperature endurance: Rated for continuous use to +135°C with a 2000‑hour endurance rating, reducing risk of premature capacitor failure in hot environments.
• Temperature‑validated ESR: ESR specified after −40°C testing and measured at 100 kHz (150 mΩ), providing deterministic impedance behavior across temperature extremes.
• Compact SMD can: 1 × 1 cm footprint and defined land pattern (1.03 × 1.03 cm) minimize board area while remaining compatible with automated carrier‑tape assembly.
• Automotive‑grade qualification: AEC‑Q200 qualification supports use in applications that require documented reliability standards.
• Designed for real‑world ripple: Specified ripple current ratings at both low (120 Hz) and high (10 kHz) frequencies enable selection for switching and line‑powered circuits.
• RoHS compliant: Meets current RoHS requirements for restricted substances in electronic assemblies.
