UCZ1C331MCL1GS

The UCZ1C331MCL1GS is a chip‑type aluminum electrolytic capacitor designed for high‑reliability, high‑temperature electronic applications. It is a polarized, surface‑mount can package engineered for operation from −40 °C to +125 °C and is AEC‑Q200 qualified with RoHS compliance.

With a 330 µF capacitance at 16 V, low‑temperature ESR specification and proven endurance at elevated temperature, this part targets applications that require robust decoupling and energy smoothing in demanding thermal and mechanical environments.

Key Features

• Chip‑type aluminum electrolytic construction — Polarized SMD can package optimized for surface mounting and automatic placement from carrier tape.
• High‑temperature operation — Rated for an operating temperature range of −40 °C to +125 °C with an endurance specification of 3000 hours at 125 °C.
• AEC‑Q200 qualified & RoHS compliant — Designed to meet automotive reliability expectations and environmental directives specified in the product data.
• Low‑temperature ESR specification — ESR characterized after −40 °C testing, with an equivalent series resistance of 150 mΩ at 100 kHz to support stable performance across temperature extremes.
• Ripple current capability — Rated ripple currents of 250 mA at 120 Hz and 500 mA at 10 kHz for smoothing and decoupling in power circuits.
• Soldering heat resistance — Meets the datasheet resistance to soldering heat condition (hot plate at 250 °C for 30 seconds) while maintaining specified electrical characteristics.
• Compact SMD footprint — Case size and package dimension L: 1 × D: 1 cm with recommended surface‑mount land size L: 1.03 × W: 1.03 cm for PCB layout.

Typical Applications

• Automotive electronics — Suited for electronic modules and control units requiring AEC‑Q200 qualification and reliable operation up to +125 °C.
• High‑temperature industrial electronics — Filtering and decoupling in power assemblies that must tolerate elevated ambient temperatures and prolonged thermal stress.
• Surface‑mount power supplies and DC‑DC converters — SMD can package and defined ripple current ratings support use for output smoothing and transient suppression on compact PCBs.

Unique Advantages

• Proven high‑temperature endurance: 3000 hours at 125 °C provides predictable long‑term performance in hot environments.
• Automotive‑grade reliability: AEC‑Q200 qualification supports designs targeting automotive and other high‑reliability markets.
• Low‑temperature performance assurance: ESR specification after −40 °C testing helps ensure consistent behavior in cold starts and low‑temperature conditions.
• Measurable ripple handling: Dual ripple current ratings at 120 Hz and 10 kHz give clear limits for power supply and converter design tradeoffs.
• Assembly‑friendly SMD format: Tape‑feed compatibility and a compact land pattern simplify automated placement and PCB layout.
• RoHS compliance: Meets environmental directive requirements specified in the product data.
