UCX1E102MNJ1MS

The UCX1E102MNJ1MS is a chip‑type aluminum electrolytic capacitor in Nichicon’s UCX series, offering 1 mF capacitance at 25 V with polarization for board‑level power applications. It is designed for sustained operation across a wide temperature range (−40 °C to +135 °C) and is AEC‑Q200 qualified for use in automotive and other demanding environments. Key value propositions include high‑temperature endurance, a specified low‑temperature ESR, and an SMD can package suited for automated placement.

Key Features

• Capacitance & Voltage — 1 mF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20%.
• Temperature Range & Endurance — Rated for operation from −40 °C to +135 °C; endurance specified as 2000 hours at 135 °C with defined limits for capacitance change, tan δ and leakage after the endurance test.
• Low‑temperature ESR Specified — ESR defined following the −40 °C test to ensure predictable performance at cold temperatures.
• ESR & Frequency Performance — Equivalent series resistance of 70 mΩ measured at 100 kHz, supporting high‑frequency ripple handling.
• Ripple Current Ratings — 375 mA at 120 Hz and 750 mA at 10 kHz, enabling effective smoothing and decoupling under AC ripple conditions.
• Package & Mounting — Chip type, radial can SMD package intended for surface mount assembly and compatible with carrier‑tape automated placement; compact footprint with dimensions L: 1.35 × D: 1.25 cm and recommended land size L: 1.28 × W: 1.28 cm.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), suitable for regulated markets and applications requiring component qualification.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and operation to +135 °C make this capacitor suitable for electronic control units and modules exposed to elevated temperatures.
• Power supply smoothing in high‑temperature environments — High ripple current ratings and a specified ESR at 100 kHz support bulk decoupling and filtering where thermal stress is present.
• Board‑level assemblies requiring automated placement — Chip‑type SMD can and carrier‑tape compatibility enable efficient surface‑mount assembly and integration on dense PCBs.

Unique Advantages

• High‑temperature endurance: Rated and endurance‑tested at 135 °C for 2000 hours, providing predictable long‑term behavior in hot environments.
• Cold‑start performance assurance: ESR characterized after −40 °C testing to ensure performance across the full temperature range.
• Measured high‑frequency behavior: 70 mΩ ESR at 100 kHz and a 750 mA ripple rating at 10 kHz help maintain stability in switching and high‑frequency circuits.
• Automotive‑grade qualification: AEC‑Q200 status supports selection for vehicle electronics and other applications requiring component reliability documentation.
• Surface‑mount convenience: Chip‑type radial can in an SMD format compatible with carrier tape reduces assembly complexity for volume production.
