UCH1J680MCS1GS

The UCH1J680MCS1GS is a chip-type aluminum electrolytic capacitor engineered for high-reliability applications. It provides 68 µF capacitance at 63 V in a compact surface-mount can package designed for automated assembly.

Targeted use includes automotive electronics and other systems that require stable performance across a wide temperature range, with specific emphasis on low-temperature ESR behavior and long-term endurance at elevated temperatures.

Key Features

• Capacitance & Voltage — 68 µF rated capacitance at 63 V with a tolerance of ±20% (120 Hz, 20°C).
• Low-temperature ESR Specification — Added ESR specification after test at −40°C and defined impedance stability at low temperatures to support cold-environment performance.
• Reliability & Endurance — AEC-Q200 qualified with specified endurance of 2000 hours at 125°C; capacitance, tan δ and leakage current criteria are defined after recovery to 20°C.
• Surface-mount Can Package — Radial can configured for SMD applications and applicable to automatic mounting machines fed with carrier tape; surface-mount land size specified as 8.3 × 8.3 mm.
• Operating Range — Rated to operate from −40°C to 125°C, with series-level stability limits provided for temperature and frequency.
• ESR and Ripple Handling — Equivalent series resistance specified at 400 mΩ (measured at 100 kHz); ripple current ratings include 125 mA at 120 Hz and 250 mA at 10 kHz.
• RoHS Compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — AEC-Q200 qualification makes the capacitor suitable for vehicular electronic modules that require robustness and defined endurance at elevated temperatures.
• Automated SMD assembly — Designed for use with carrier-tape fed automatic mounting machines to support high-volume, repeatable surface-mount production.
• Cold-environment systems — Low-temperature ESR specification and added ESR verification after −40°C testing support designs that must maintain performance in cold conditions.

Unique Advantages

• Automotive-grade qualification — AEC-Q200 rating provides an explicit basis for selection in automotive designs that require standardized component qualification.
• Verified low-temperature ESR — Additional ESR specification after −40°C testing reduces uncertainty for designers targeting cold-start or low-temperature operation.
• High-temperature endurance — 2000 hours at 125°C endurance characterization supports use in thermally demanding environments and long-life applications.
• SMD-compatible can package — Radial can configured for surface-mount with carrier-tape compatibility to streamline PCB assembly and reduce handling complexity.
• Defined ripple and ESR performance — Explicit ESR (400 mΩ at 100 kHz) and ripple current ratings (120 Hz and 10 kHz values) let engineers size and verify thermal and ripple performance in power circuits.
• Regulatory compliance — RoHS conformity simplifies environmental compliance planning for OEMs and contract manufacturers.
