UCX1V680MCS1GS

The UCX1V680MCS1GS is a chip‑type aluminum electrolytic capacitor from Nichicon’s UCX series engineered for high‑temperature operation up to +135°C. It is designed for surface‑mount assembly (carrier‑tape compatible) and includes ESR characterization that covers low‑temperature performance after a −40°C test.

Targeted for demanding environments, this part combines AEC‑Q200 qualification, RoHS compliance, and specified endurance to deliver predictable behavior in long‑life, high‑temperature electronic systems.

Key Features

• Capacitance & Voltage: 68 µF rated at 35 V to support decoupling and bulk energy tasks within that voltage class.
• High‑temperature endurance: Specified for operation from −40°C to +135°C with a rated lifetime of 2000 hours at 135°C; capacitance change after endurance is within ±30% per datasheet endurance conditions.
• Low‑temperature ESR specification: ESR defined as 200 mΩ at 100 kHz, with ESR performance also specified following a −40°C test to ensure behavior across the operating range.
• Ripple current capability: Rated ripple current of 135 mA at 120 Hz and 270 mA at 10 kHz for AC stress handling across common frequencies.
• Surface‑mount, tape‑feedable package: Chip‑type radial can SMD package suitable for automated placement from carrier tape; compact footprint L: 1 cm × D: 0.8 cm with a recommended land size of 8.3 × 8.3 mm.
• Automotive qualification & RoHS compliance: AEC‑Q200 Qualified and compliant with RoHS directives (2011/65/EU, (EU)2015/863), supporting regulated design requirements.

Typical Applications

• Automotive electronics: Suitable for control modules and electronic assemblies that require AEC‑Q200 qualification and reliable operation from −40°C to +135°C.
• High‑temperature electronic systems: Designed for assemblies and subsystems exposed to sustained elevated temperatures where long endurance (2000 h at 135°C) is required.
• Automated surface‑mount production: Carrier‑tape compatible chip package enables placement on automated mounting machines for high‑volume PCB assembly.

Unique Advantages

• Specified high‑temperature lifetime: 2000 hours at 135°C with controlled post‑test limits on capacitance, tan δ, and leakage current ensures predictable aging under thermal stress.
• Low‑temperature ESR characterization: ESR rating (200 mΩ at 100 kHz) plus ESR specification after −40°C testing provides confidence in performance across the full −40°C to +135°C range.
• SMD compatibility for automated assembly: Chip‑type radial can packaged for carrier‑tape handling simplifies integration into high‑throughput manufacturing lines.
• Frequency‑rated ripple handling: Distinct ripple current ratings at 120 Hz and 10 kHz support reliable AC performance across common application frequencies.
• Regulatory and reliability credentials: AEC‑Q200 qualification and RoHS compliance support regulated design flows and supply‑chain requirements.
