UCX1H102MNJ1MS

The UCX1H102MNJ1MS is a chip‑type aluminum electrolytic capacitor in a surface‑mount radial can package. It delivers 1 mF capacitance at a 50 V rating, polarized and designed for assembly on automatic mounting machines fed with carrier tape.

Engineered for high‑temperature operation, this part is specified for an operating range of −40 °C to +135 °C and carries AEC‑Q200 qualification and RoHS compliance, making it suitable for demanding electronics environments that require defined endurance and ESR behavior.

Key Features

• Temperature range & endurance — Rated for −40 °C to +135 °C with an endurance specification of 2000 hours at 135 °C.
• Electrical ratings — 1 mF capacitance with ±20% tolerance and a rated voltage of 50 V.
• Low‑loss characteristic — Specified tangent of loss angle (tan δ) for 50 V is 0.16 (measured at 120 Hz, 20 °C) per series specifications.
• ESR characterization — Equivalent series resistance specified as 50 mΩ at 100 kHz; an ESR specification was added following the −40 °C test.
• Ripple current capability — Rated ripple current of 800 mA at 120 Hz and 1.6 A at 10 kHz, supporting both low‑ and high‑frequency power conditions.
• Surface‑mount ready — Radial, can‑style SMD package designed for automatic mounting machines using carrier tape; recommended land pattern L: 1.63 × W: 1.63 cm.
• Qualification & environmental — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and +135 °C endurance make this capacitor suitable for automotive electronic modules requiring high‑temperature reliability.
• High‑temperature power circuits — Designed for power filtering and decoupling in electronics exposed to elevated temperatures up to 135 °C.
• Surface‑mount production — Package and tape feed compatibility enable placement on automated assembly lines for compact SMD designs.
• AEC‑Q200 qualified designs — Intended for systems that specify AEC‑Q200 components for component‑level qualification.

Unique Advantages

• High‑temperature durability: 2000‑hour endurance at 135 °C provides a quantifiable reliability metric for thermal stress conditions.
• Defined ESR performance: 50 mΩ ESR at 100 kHz and additional ESR data after −40 °C testing help designers predict behavior across temperature extremes.
• Broad ripple handling: Dual ripple current ratings (800 mA at 120 Hz, 1.6 A at 10 kHz) support both mains‑frequency and high‑frequency power domains.
• Surface‑mount compatibility: Radial can SMD format and carrier‑tape readiness streamline automated assembly for compact boards.
• Industry qualification & compliance: AEC‑Q200 qualification and RoHS compliance address regulatory and industry quality requirements.
