UCX1A331MCS6GS

The UCX1A331MCS6GS is a chip‑type aluminum electrolytic capacitor designed for surface‑mount assembly and high‑temperature operation. It delivers 330 μF at 10 V in a compact SMD can package with polarization and a ±20% tolerance.

Targeted for demanding environments, this part combines an extended operating range (‑40 °C to +135 °C), AEC‑Q200 qualification, and ESR characterization that includes low‑temperature performance — making it suitable for automotive and other high‑temperature electronic systems that require reliable bulk capacitance in a small footprint.

Key Features

• Capacitance & voltage — 330 μF nominal capacitance at a 10 V rated voltage with ±20% tolerance for bulk energy storage and decoupling.
• High‑temperature operation — Rated for −40 °C to +135 °C operation with endurance specified at 2000 hours at 135 °C.
• AEC‑Q200 qualified — Series qualification noted for designs requiring AEC‑Q200 level reliability.
• Low‑temperature ESR characterization — ESR specified after −40 °C testing to support designs that must maintain performance across wide temperature swings; ESR = 200 mOhm at 100 kHz.
• Ripple current handling — Specified ripple capability of 135 mA at 120 Hz (low frequency) and 270 mA at 100 kHz (high frequency).
• Surface‑mount can package — Chip‑type, radial can in an SMD configuration suitable for automated placement; physical size L: 1 cm × D: 0.8 cm and recommended land size 8.3 × 8.3 mm.
• Polarized design — Standard electrolytic polarity for bulk filtering and smoothing in DC power systems.
• RoHS compliant — Manufactured in compliance with RoHS directives.

Typical Applications

• Automotive electronic systems — Bulk decoupling and smoothing in automotive modules where AEC‑Q200 qualification and +135 °C endurance are required.
• High‑temperature electronics — Power filtering and energy storage in equipment exposed to elevated ambient temperatures, supported by the 2000 h endurance at 135 °C.
• Surface‑mount power assemblies — Automated placement on compact PCBs that require a polarized SMD can capacitor with defined land pattern and package dimensions.

Unique Advantages

• Proven high‑temperature endurance: Rated for 2000 hours at 135 °C, providing documented lifecycle performance for thermal‑stress environments.
• Qualification for automotive use: AEC‑Q200 rating supports integration into automotive electronic designs where qualified components are required.
• Wide operating temperature range: −40 °C to +135 °C with ESR characterized after −40 °C testing, enabling operation across extreme temperature swings.
• Compact SMD can footprint: 1.0 × 0.8 cm package and 8.3 × 8.3 mm recommended land pattern optimize board area while retaining high capacitance.
• Frequency‑aware ripple performance: Separate ripple current specifications at 120 Hz and 100 kHz allow designers to assess low‑ and high‑frequency ripple handling.
• Manufacturing ready: Chip type compatible with carrier‑tape automated mounting for high‑volume, repeatable assembly.
