The UCK1E292MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. It delivers 2.9 mF capacitance at a 25 V rating with a polarized configuration and is optimized for automated placement using carrier tape.

Engineered for demanding environments, this capacitor supports a wide operating temperature range (−55°C to +105°C) and carries AEC-Q200 qualification, making it suitable for automotive and other reliability-focused applications where stable smoothing and decoupling are required.

Key Features

• Capacitance & Voltage — 2.9 mF nominal capacitance at a 25 V rated voltage with ±20% tolerance for bulk energy storage and power-rail smoothing.
• Low Impedance Performance — Chip-type low-impedance construction for improved ripple handling and transient response.
• Ripple Current Capability — Rated for 955 mA at 120 Hz and 1.91 A at 10 kHz to support high ripple environments and switching power supplies.
• Temperature & Lifetime — Operating range −55°C to +105°C with endurance specified as 5000 hours at 105°C, supporting long-term reliability under elevated temperatures.
• Automotive-Grade Qualification — AEC-Q200 qualified and noted for automotive applications in the product data.
• Surface-Mount Package — Surface-mount, radial can (SMD) package with physical dimensions L: 1.65 × D: 1.6 cm and a specified surface-mount land size of 1.63 × 1.63 cm; suitable for automated tape-fed placement.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Use for power-rail decoupling and smoothing in automotive control modules where AEC-Q200 qualification and extended temperature range are required.
• Power Supply Filtering — Bulk filtering and ripple suppression in DC–DC converters and regulator outputs, leveraging high ripple current ratings.
• Embedded Systems — Energy storage and transient buffering for microcontroller power domains and board-level decoupling in robust designs.

Unique Advantages

• Designed for Automated Assembly: Carrier-tape compatibility and an SMD can package enable reliable high-volume placement and consistent board-level yield.
• High Ripple Current Handling: Specified ripple currents at 120 Hz and 10 kHz reduce heating and extend system reliability in switching environments.
• Wide Temperature Endurance: −55°C to +105°C operation and 5000-hour endurance at 105°C provide predictable performance in thermal-stressed applications.
• AEC-Q200 Qualification: Qualification per AEC-Q200 supports deployment in automotive-grade designs requiring recognized component qualification.
• RoHS Compliance: Meets RoHS directives for use in environmentally regulated product lines.
