UCX1E102MNQ1MS

The UCX1E102MNQ1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature, high-reliability applications. It is a surface-mount, carrier-tape compatible can package offering 1 mF capacitance at a 25 V rated voltage with AEC‑Q200 qualification.

Engineered for extended operation between −40°C and +135°C, this part is targeted at designs that require robust ripple handling, controlled ESR across temperature extremes, and long-term endurance in demanding environments.

Key Features

• Electrical Performance — 1 mF nominal capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20°C) and a specified ESR of 70 mΩ at 100 kHz.
• Temperature & Endurance — Rated for continuous operation from −40°C to +135°C with a specified lifetime of 2000 hours at 135°C; endurance criteria include capacitance change within ±30% and leakage current remaining at or below initial specification after the test.
• Ripple Capability — Defined ripple current ratings of 375 mA at 120 Hz and 750 mA at 10 kHz provide guidance for power-filtering and decoupling roles.
• Low‑temperature ESR Specification — ESR is specified after the −40°C test, supporting predictable performance at low ambient temperatures.
• Surface-mount, Carrier-tape Compatible — Chip-type radial can SMD package sized L: 1.35 cm × D: 1.25 cm, with recommended land size L: 1.28 × W: 1.28 cm for automated placement.
• Standards & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).
• Soldering Resistance — Meets resistance-to-soldering-heat criteria (30 s at 250°C hot-plate condition) with capacitance change within ±10% after the test.
• Case Marking — Black print on the case top for clear identification.

Typical Applications

• Automotive Power Modules — Used in on-board power filtering and decoupling where AEC‑Q200 qualification and operation to +135°C are required.
• Engine and Powertrain Electronics — Suitable for high-temperature locations on engine control and power distribution PCBs that demand long endurance at elevated temperature.
• Industrial Power Supplies — Useful where compact SMD electrolytic capacitance and defined ripple handling are needed for high-temperature operation.

Unique Advantages

• High-temperature endurance: Specified lifetime of 2000 hours at 135°C delivers predictable long-term performance in hot environments.
• AEC‑Q200 qualification: Enables selection for automotive-grade designs that require component-level reliability verification.
• Controlled ESR across temperature: ESR specified at 100 kHz and confirmed after −40°C testing supports predictable behavior from cold start to high-temperature operation.
• Compact SMD can package: Chip-type surface-mount construction with carrier-tape compatibility simplifies automated assembly for dense board layouts.
• Defined ripple handling: Published ripple current ratings at 120 Hz and 10 kHz give clear guidance for thermal and ripple management in power circuits.
• Regulatory compliance: RoHS conformity and clear case marking streamline regulatory and traceability requirements.
