UCX1A331MCL6GS

The UCX1A331MCL6GS is a chip‑type aluminum electrolytic capacitor designed for high‑temperature operation up to +135°C. It delivers 330 µF at 10 V in a compact surface‑mount package compatible with carrier‑tape automated assembly.

Targeted for demanding environments, the device combines a high operating temperature range, explicit low‑temperature ESR characterization, and AEC‑Q200 qualification, making it suitable for designs that require reliable bulk capacitance and thermal endurance.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a rated voltage of 10 V with a tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• High‑Temperature Rating — Rated operating temperature range of −40°C to +135°C with an endurance specification of 2000 hours at 135°C.
• Low‑temperature ESR Specification — ESR characterized (200 mΩ at 100 kHz) and an added ESR specification after the −40°C test, helping predict performance across temperature extremes.
• Ripple Current Performance — Rated ripple currents of 135 mA at 120 Hz and 270 mA at 10 kHz for decoupling and smoothing in power paths.
• Surface‑Mount Chip Package — Chip (radial, can‑SMD) package designed for surface mount placement; compatible with automatic mounting machines fed by carrier tape. Recommended PCB land size: 8.3 × 8.3 mm.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated environments and long‑term reliability requirements.

Typical Applications

• Automotive electronics — Bulk smoothing and decoupling in modules and systems that require AEC‑Q200 qualification and operation at elevated temperatures.
• High‑temperature power modules — Local energy storage and transient suppression in boards exposed to sustained high ambient temperature.
• Automated SMT production — Surface‑mount chip form factor and carrier‑tape compatibility for efficient pick‑and‑place assembly in volume manufacturing.

Unique Advantages

• Designed for elevated temperatures — Rated to −40°C to +135°C with a 2000‑hour endurance at 135°C, supporting prolonged operation in hot environments.
• AEC‑Q200 qualification — Explicit qualification for applications requiring automotive‑grade reliability and traceable performance expectations.
• Characterized ESR at low temperature — ESR specified (200 mΩ at 100 kHz) with post‑−40°C test data to help validate performance in cold starts and wide thermal cycles.
• SMD form factor for automated assembly — Chip‑type, can‑SMD package and carrier‑tape compatibility reduce assembly complexity and accelerate production flow.
• Practical ripple handling — Specified ripple currents at both 120 Hz and 10 kHz to support filtering and decoupling across a range of power applications.
• Regulatory compliance — RoHS compliant for use in regulated product lines and global markets.
