UCJ1E331MCL1GS

The UCJ1E331MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UCJ series, designed for surface-mount assembly and high-temperature operation. It delivers 330 µF at a 25 V rating with AEC-Q200 qualification and a wide operating temperature range from −40 °C to +125 °C.

Built for automated production, this SMD can is carrier-tape compatible and targets designs that require elevated temperature endurance and controlled electrical performance across temperature extremes.

Key Features

• Capacitance & Voltage — Rated at 330 µF and 25 V with a tolerance of ±20% (−20% to +20%).
• High‑Temperature Operation — Specified for continuous use up to +125 °C with endurance of 2000 hours at 125 °C.
• Low‑Temperature ESR Specification — ESR performance is specified after the −40 °C test to ensure predictable behavior at low temperatures.
• Ripple Current Capability — Rated ripple currents: 200 mA at 120 Hz and 400 mA at 10 kHz, supporting AC and switching conditions.
• Surface‑Mount, Tape‑Fed Package — Chip-type, can-style SMD designed for automatic mounting machines fed with carrier tape; package/case listed as Radial, Can - SMD.
• Reliability & Standards — AEC‑Q200 qualified and RoHS compliant, with leakage current and tan δ limits defined in the UCJ series specifications.
• Compact Footprint — Physical dimensions L: 1 × D: 1 cm and recommended land pattern L: 1.03 × W: 1.03 cm for PCB layout.

Typical Applications

• Automotive Electronics — Use in automotive electronic modules where AEC‑Q200 qualification and −40 °C to +125 °C operation are required.
• High‑Temperature Electronic Systems — Suitable for assemblies and subsystems that must withstand elevated ambient or board temperatures up to +125 °C.
• Surface‑Mount Power Assemblies — Designed for automated SMD assembly processes using carrier tape for efficient production and repeatable placement.
