UCX1V680MCL1GS

The UCX1V680MCL1GS is a chip‑type aluminum electrolytic capacitor from Nichicon's UCX series designed for high‑temperature operation up to +135°C. It combines a 68 µF capacitance with a 35 V rated voltage in a surface‑mount, carrier‑tape compatible package intended for automated assembly.

Targeted at applications requiring elevated temperature endurance and automotive‑grade reliability, this capacitor delivers specified ESR, ripple current performance, and a 2000‑hour endurance rating at 135°C for robust power filtering and decoupling in demanding environments.

Key Features

• Electrical Performance — 68 µF nominal capacitance at 35 V, with ±20% tolerance, polarized design for DC power applications.
• High‑Temperature Capability — Rated operating temperature range −40 °C to +135 °C with endurance specified for 2000 hours at 135 °C.
• ESR and Ripple Handling — Equivalent series resistance of 200 mΩ measured at 100 kHz; ripple current ratings of 135 mA at 120 Hz and 270 mA at 10 kHz.
• Automotive Qualification — AEC‑Q200 qualified for designs that require automotive‑level component qualification.
• Assembly‑Ready Package — Chip type, surface‑mount, radial can SMD format suitable for automatic mounting machines fed with carrier tape; surface mount land size 8.3 × 8.3 mm.
• Endurance & Stability — Endurance specification: after 2000 hours at 135 °C with rated voltage applied, capacitance change within ±30% and leakage current within initial specified limits.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Suitable for electronic modules and control units where AEC‑Q200 qualification and high operating temperature are required.
• High‑Temperature Power Systems — Use in power filtering and decoupling in systems exposed to elevated ambient temperatures up to +135 °C.
• Automated Surface‑Mount Production — Designed for placement on automated assembly lines using carrier tape, easing high‑volume manufacturing.

Unique Advantages

• High‑temperature endurance: 2000‑hour specification at 135 °C provides defined long‑term performance for thermal‑stress environments.
• Automotive‑grade qualification: AEC‑Q200 status gives explicit qualification for designs targeting automotive applications.
• Measured ESR specification: 200 mΩ at 100 kHz with ESR behavior defined after −40 °C testing for assured low‑temperature performance.
• Assembly efficiency: Surface‑mount, carrier‑tape compatibility and compact footprint (L: 1 cm × D: 0.8 cm) simplify automated placement and PCB layout.
• Clear endurance limits: Specified limits for capacitance change and leakage after high‑temperature endurance offer predictable lifecycle planning.
