UCX1E332MNJ1MS

The UCX1E332MNJ1MS from Nichicon is a chip-type aluminum electrolytic capacitor designed for high-temperature operation up to +135°C. It delivers bulk capacitance in a compact surface-mount radial can (SMD) package and is intended for automated PCB assembly using carrier tape.

Targeted at demanding environments, this AEC-Q200 qualified, RoHS-compliant capacitor offers low equivalent series resistance and defined ripple-current capability for reliable filtering and energy storage in temperature-critical electronics.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 μF) rated at 25 V with ±20% tolerance for bulk energy storage and smoothing.
• High Temperature Range — Rated for operation from −40°C to +135°C with specified endurance of 2000 hours at 135°C.
• Low ESR — 35 mΩ equivalent series resistance specified at 100 kHz; ESR characterization includes post-test specification after −40°C testing.
• Ripple Current Performance — 1.1 A at 120 Hz and 2.2 A at 10 kHz to support high ripple environments in power circuits.
• Reliability & Qualification — AEC-Q200 qualified and RoHS compliant for use in regulated and reliability-focused applications.
• Surface-Mount, Tape-Feed Compatible — Radial can SMD package designed for automatic mounting machines fed with carrier tape; compact footprint with L: 2.15 × D: 1.80 cm and recommended land size L: 1.83 × W: 1.83 cm.
• Polarized Design — Polarized aluminum electrolytic capacitor suitable for DC power applications requiring polarized components.

Typical Applications

• Automotive electronics — Power rail smoothing and bulk decoupling in high-temperature vehicle zones, supported by AEC-Q200 qualification and 135°C endurance.
• Power conversion and motor drives — Energy smoothing and ripple handling in converters and inverters where the 1.1 A (120 Hz) and 2.2 A (10 kHz) ripple ratings are required.
• Industrial control equipment — Bulk capacitance and filtering in temperature-challenged enclosures, leveraging the −40°C to +135°C operating range and 2000-hour high-temperature lifetime.
• Embedded power modules — Local energy storage and decoupling near power ICs where low ESR (35 mΩ at 100 kHz) improves transient response and efficiency.

Unique Advantages

• Extended high-temperature endurance: 2000 hours at 135°C provides predictable longevity in temperature-critical designs.
• Defined low-temperature ESR performance: ESR specified after −40°C testing ensures predictable behavior across the operating temperature range.
• High ripple capability: Dual-frequency ripple ratings (120 Hz and 10 kHz) cover both low-frequency smoothing and higher-frequency switching environments.
• Automated assembly ready: Carrier-tape compatibility and SMD radial-can packaging simplify high-volume PCB assembly.
• Industry qualification: AEC-Q200 qualification and RoHS compliance support use in regulated and reliability-focused supply chains.
• Compact SMD footprint: Small L × D dimensions and recommended land pattern enable high-density board layouts.
