UWX1E330MCL1GB

The UWX1E330MCL1GB is a chip-type aluminum electrolytic capacitor in the Nichicon UWX series designed for surface mounting on high-density PC boards. It delivers 33 µF capacitance at a 25 V rating in a compact SMD can package with a 5.4 × 6.3 mm footprint and a seated height of 5.4 mm.

Engineered for embedded and automotive electronics, this AEC-Q200–rated, RoHS-compliant capacitor offers a 2,000-hour load life at 85 °C, making it suitable for designs that require stable capacitance and reliable operation across −40 °C to +85 °C.

Key Features

• Compact SMD Chip Package Chip-type radial can SMD package sized L: 5.4 × D: 6.3 mm with a recommended surface-mount land of 6.6 × 6.6 mm for high-density PCB layouts.
• Electrical Characteristics 33 µF nominal capacitance at 25 V with ±20% tolerance and polarized construction for power filtering and decoupling applications.
• Thermal and Life Performance Rated for operation from −40 °C to +85 °C with a specified load life of 2,000 hours at 85 °C for predictable endurance under elevated temperatures.
• Ripple Current Ratings Ripple current handling of 52 mA at 120 Hz and 78 mA at 10 kHz, useful for both low- and higher-frequency power-conditioning tasks.
• Low Leakage Current Leakage current specification: after 2 minutes at rated voltage and 20 °C, leakage is ≤ 0.01CV or 3 µA (whichever is greater), supporting low-standby-power designs.
• Assembly and Mounting Designed for surface mounting on high-density PCBs and suitable for automatic placement when supplied on carrier tape.
• Standards and Compliance AEC-Q200 compliant and RoHS directive (2011/65/EU, (EU)2015/863) compliant.

Typical Applications

• Automotive Electronic Modules Local power decoupling and smoothing for compact automotive control modules where AEC-Q200 qualification is required.
• Embedded Power Supplies Bulk and decoupling capacitance on high-density PCBs for embedded systems operating up to 25 V.
• Sensors and Control Units Power conditioning in sensor interfaces and small control units that demand a stable capacitor with defined life at elevated temperature.

Unique Advantages

• Automotive-Grade Qualification: AEC-Q200 compliance provides design assurance for automotive electronics and other demanding environments.
• Compact, High-Density Friendly: Chip-type SMD can with a small footprint and carrier-tape compatibility simplifies placement on crowded PCBs and automated assembly.
• Engineered Endurance: 2,000-hour load life at 85 °C gives predictable long-term performance for designs exposed to sustained elevated temperatures.
• Measurable Leakage Performance: Clear leakage-current specification (≤ 0.01CV or 3 µA after 2 minutes at 20 °C) supports low-leakage design requirements.
• Frequency-Aware Ripple Handling: Published ripple current values at 120 Hz and 10 kHz help select and qualify the part for both low- and medium-frequency power tasks.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for restricted-substance requirements.
