UCK1E452MNJ1MS

The UCK1E452MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. With a high capacitance of 4500 µF at 25 V and a compact φ16 × 21.5 mm can, it addresses high-energy smoothing and ripple-handling needs in demanding electronic systems.

Engineered for automotive and industrial markets, this part combines wide operating temperature (-55°C to 105°C), AEC-Q200 qualification, and RoHS compliance with carrier-tape packaging suitable for automated placement.

Key Features

• Capacitance & Tolerance: 4500 µF nominal with ±20% tolerance at 120 Hz, 20°C, providing a large energy reservoir for bulk decoupling and smoothing.
• Rated Voltage: 25 V DC rating for low-voltage power rails and DC-link applications.
• Low Impedance / High Ripple Capability: Low-impedance chip construction with specified ripple currents of 1.27 A at 120 Hz and 2.54 A at 10 kHz to support both low- and high-frequency ripple demands.
• Leakage Current: Specified leakage current of 1125 µA, defined per rated conditions.
• High-Temperature Endurance: Rated for 5000 hours at 105°C with defined endurance limits (capacitance change within ±30%, tan δ ≤200% of initial, leakage ≤ initial).
• Wide Temperature Range: Operates from −55°C to +105°C for reliable performance across automotive and industrial temperature extremes.
• Surface-Mount Packaging: Radial can SMD package (φ16 × 21.5L) with embossed carrier taping for automatic pick-and-place mounting; recommended land size L: 1.63 × W: 1.63 cm.
• Qualification & Compliance: AEC-Q200 qualified and RoHS compliant for regulated environments and automotive program requirements.

Typical Applications

• Automotive power systems: Bulk filtering and smoothing on vehicle power rails and control modules where temperature endurance and AEC-Q200 qualification are required.
• ECU and power module decoupling: Energy storage and ripple suppression for electronic control units and power-stage outputs that demand high capacitance in an SMD form factor.
• Infotainment and body electronics: Power stabilization and transient buffering in infotainment, gateway, and body-control subsystems operating across wide temperature ranges.
• Automated PCB assembly: Designed for embossed carrier taping to support high-volume surface-mount assembly processes.

Unique Advantages

• High capacitance in a compact SMD can: 4500 µF in a φ16 × 21.5 mm package delivers significant energy density without a through-hole footprint.
• Designed for ripple-heavy applications: Specified low- and high-frequency ripple currents (1.27 A @120 Hz, 2.54 A @10 kHz) help maintain voltage stability under dynamic loads.
• Long high-temperature life: 5000-hour endurance at 105°C enables predictable long-term performance in elevated-temperature environments.
• Automotive program readiness: AEC-Q200 qualification and −55°C to +105°C operating range support use in automotive electronics and similarly demanding systems.
• Assembly-friendly packaging: Embossed carrier taping supports automated pick-and-place, reducing manual handling and speeding production.
• Regulatory compliance: RoHS compliance ensures suitability for regulated product lines and markets.
