UCX1E332MNQ1MS

The UCX1E332MNQ1MS is a chip-type aluminum electrolytic capacitor designed for high-temperature operation up to +135°C. It delivers 3.3 mF (3300 μF) capacitance at a 25 V rating in a surface-mount, tape-fed package optimized for automated assembly.

Engineered for demanding environments, this polarized SMD can supports high ripple currents and includes ESR specification after low-temperature testing, making it suitable for robust power and control electronics where long-term thermal endurance is required.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 μF) nominal capacitance with a 25 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• High-Temperature Operation — Specified operating range from −40 °C to +135 °C with a rated lifetime of 2000 hours at 135 °C for sustained thermal reliability.
• ESR and Ripple Performance — ESR specified at 35 mΩ (measured at 100 kHz) and ripple current ratings of 1.1 A at 120 Hz and 2.2 A at 10 kHz to support high-frequency and low-frequency ripple demands.
• Endurance & Stability — Endurance requirements defined after 2000 hours at 135 °C: capacitance change within ±30%, tan δ within 300% of initial, and leakage current no greater than initial specified value.
• Surface-Mount, Tape-Fed Package — Chip-type radial can SMD package designed for automatic mounting machines fed with carrier tape to streamline high-volume assembly.
• Compliance & Qualification — RoHS compliant and AEC-Q200 qualified, supporting use in regulated and qualification-sensitive applications.
• Polarized Construction — Designed as a polarized electrolytic capacitor for typical power rail and bulk storage uses.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and −40 °C to +135 °C operation make it suitable for control modules and power electronics in automotive systems.
• Power Conversion & DC–DC Modules — High capacitance, defined ESR, and rated ripple currents support smoothing and energy buffering in converters and power supplies.
• Motor Drives & Powertrain Control — Thermal endurance and high ripple capability address the demands of motor controllers and powertrain electronics operating at elevated temperatures.
• Battery Management & Energy Storage — Bulk capacitance and robust lifetime at high temperatures assist in transient handling and charge/discharge stabilization.

Unique Advantages

• Proven High-Temperature Endurance: Rated for continuous operation to +135 °C with a verified 2000-hour lifetime at that temperature for predictable aging and maintenance planning.
• Specified Low-Temperature ESR: ESR specified after −40 °C testing provides measurable performance across the full operating temperature range, reducing design uncertainty.
• Assembly-Ready SMD Package: Tape-fed chip-type can for automatic placement simplifies integration into modern SMT production lines.
• Measured Ripple Handling: Explicit ripple current ratings at both low and high frequencies (1.1 A at 120 Hz; 2.2 A at 10 kHz) help match capacitor selection to converter and filter requirements.
• AEC-Q200 Qualification: Industry-recognized qualification supports use in designs that require component-level reliability validation.
• Regulatory Compliance: RoHS compliance supports environmentally driven supply-chain requirements.
