UCH1J330MCL1GS

The UCH1J330MCL1GS is a chip-type, high-reliability aluminum electrolytic capacitor from Nichicon’s UCH series. It is a polarized surface-mount (radial can SMD) capacitor specified for demanding environments and automated assembly.

Designed for applications that require stable performance from -40 °C to 125 °C, this capacitor offers a 33 µF capacitance at 63 V with documented low-temperature ESR behavior and AEC‑Q200 qualification for reliability-conscious designs.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance with a 63 V rating and ±20% tolerance at 120 Hz, 20 °C.
• High‑Reliability Construction — Chip-type aluminum electrolytic design in the UCH series with AEC‑Q200 qualification and RoHS compliance.
• Wide Temperature Range — Rated for operation from -40 °C to 125 °C, with specified stability at low temperatures (Z(-40 °C)/Z(+20 °C) ≤ 3).
• Endurance at Elevated Temperature — Qualified for 2000 hours at 125 °C with defined limits on capacitance change, tan δ, and leakage current after recovery to 20 °C.
• Low‑Temperature ESR Specification — ESR characterized including after the -40 °C test to ensure reliable performance in cold conditions; baseline ESR specified as 800 mΩ at 100 kHz.
• Ripple Current Capability — Specified ripple currents of 75 mA at 120 Hz and 150 mA at 10 kHz; frequency coefficients provided for ripple current scaling.
• Surface‑Mount Packaging — Compact SMD radial can footprint (φ6.3 × 7.7 mm nominal) with surface-mount land size 6.6 × 6.6 mm; applicable to automatic mounting machines fed with carrier tape.

Typical Applications

• Automotive Electronics — Suitable for automotive modules where AEC‑Q200 qualification and wide temperature operation are required.
• High‑Temperature Systems — For electronics that must operate reliably at elevated ambient temperatures up to 125 °C with long endurance.
• Automated Surface‑Mount Production — Designed for pick-and-place assembly from carrier tape in high-volume manufacturing.

Unique Advantages

• Qualified for Automotive Reliability — AEC‑Q200 qualification provides a documented reliability baseline for use in demanding designs.
• Verified Low‑Temperature ESR — ESR specifications include measurements after -40 °C testing, reducing uncertainty for cold‑start and low‑temperature operation.
• High Thermal Endurance — 2000‑hour endurance at 125 °C supports long-term stability in high‑temperature applications.
• Compact SMD Form Factor — Small φ6.3 × 7.7 mm chip‑type can minimizes board area while supporting automated placement from carrier tape.
• Manufacturer Traceability — Part of Nichicon’s UCH series, combining series-level specifications with the manufacturer’s documented datasheet characteristics.
