UCK1E452MNS1MS

The UCK1E452MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount assembly. It provides 4.5 mF capacitance at a 25 V rating and is supplied in a carrier-tape format for automated placement.

Engineered for applications that require elevated temperature tolerance and robust performance, this capacitor supports operation from -55°C to +105°C and carries AEC-Q200 qualification and RoHS compliance.

Key Features

• Capacitance & Voltage — 4.5 mF rated capacitance at 25 V with a tolerance of -20% to +20%.
• Temperature Range & Endurance — Operating range from -55°C to +105°C with a rated life of 5000 hours at 105°C.
• Low Impedance — Chip-type, low-impedance construction optimized for decoupling and bulk energy storage in compact SMD form.
• Ripple Current Capability — Specified ripple current of 1.27 A at 120 Hz and 2.54 A at 10 kHz for use where AC ripple or switching currents are present.
• Mounting & Package — Surface-mount, radial can (SMD) package supplied on carrier tape for automatic mounting machines.
• Reliability & Compliance — AEC-Q200 qualified and RoHS compliant for demanding environments and regulatory requirements.
• Polarized Design — Polar capacitor construction for correct polarity applications.
• Size — Compact footprint with dimensions L: 2.15 cm × D: 1.6 cm and a seated height up to 2.15 cm.

Typical Applications

• Automotive Electronics — Bulk energy storage and smoothing in electronic control units where AEC-Q200 qualification and elevated temperature endurance are required.
• Power Supply Filtering — Input/output filtering and decoupling for DC–DC converters and power modules that require high ripple-current handling.
• Embedded Power Management — Local energy reservoir for startup and transient load support in compact, surface-mount assemblies fed from automated pick-and-place lines.

Unique Advantages

• AEC-Q200 Qualification: Offers a recognized automotive-grade reliability designation for designs that require industry-standard qualification.
• High-Temperature Endurance: 5000-hour lifetime at 105°C supports long-term operation in hot environments and thermal stress conditions.
• High Ripple Current Rating: Specified ripple currents at 120 Hz and 10 kHz help manage AC stress from switching power supplies and in-vehicle electrical noise.
• Surface-Mount, Tape-Fed Format: Designed for automated assembly—carrier-tape compatibility reduces handling time and accelerates production flow.
• Compact, High-Capacity Solution: 4.5 mF in a small radial-can SMD package delivers bulk capacitance where board space is constrained.
• Regulatory Compliance: RoHS-compliant construction simplifies selection for regulated markets.
