UCD1E102MNQ1MS

The UCD1E102MNQ1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount applications where low impedance and robust ripple handling are required. It provides 1000 µF capacitance at a 25 V rating in a compact φ12.5 × 13.5 mm can suitable for high-density PC boards.

Built for extended operation up to 105°C and AEC-Q200 qualified, this device targets demanding systems that require high ripple capability, long endurance, and automated assembly compatibility. Note: this part is marked Not Recommended for New Designs.

Key Features

• Capacitance & Tolerance — 1000 µF nominal with tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 25 V working voltage suitable for mid-voltage power rails.
• Low Loss / Low Impedance — tan δ = 0.14 (measured at 120 Hz, 20°C, 25 V) indicating low dissipation for improved AC performance.
• High Ripple Capability — Low-frequency ripple current 550 mA at 120 Hz and high-frequency ripple current 1.1 A at 10 kHz support bulk and switching-power filtering.
• Leakage Current — Specified leakage current of 250 µA for predictable standby loss and power budgeting.
• Temperature & Endurance — Operating range −55°C to +105°C with rated endurance of 5000 hours at 105°C for long-term stability in elevated-temperature environments.
• Package & Mounting — Chip-type radial can (SMD) in φ12.5 × 13.5L size with surface-mount land size 1.28 × 1.28 cm; supplied in embossed carrier taping for automated placement.
• Reliability & Compliance — AEC-Q200 rating and RoHS compliance stated in the product data.
• Polarity — Polarized aluminum electrolytic construction for DC bulk storage and decoupling.
• Availability Status — Not Recommended for New Designs; check availability and lifecycle before specifying.

Typical Applications

• Automotive electronic modules — Bulk filtering and decoupling on power rails where AEC-Q200 qualification is required for part selection.
• Power supply filtering — Bulk energy storage and ripple smoothing in DC-DC converters and linear supplies operating near 25 V.
• High-density PCB designs — Surface-mount chip form factor and embossed carrier tape enable automated placement on compact boards.
• Switching power stages — Supports both low- and high-frequency ripple currents for use adjacent to switching elements and regulators.

Unique Advantages

• High ripple endurance: Specified low- and high-frequency ripple currents (550 mA at 120 Hz, 1.1 A at 10 kHz) reduce thermal stress and improve performance in switching environments.
• High-temperature endurance: 5000 hours at 105°C provides long-term stability for applications exposed to elevated temperatures.
• Automotive-capable qualification: AEC-Q200 rating supports use in applications that call for established automotive component screening.
• Automated assembly ready: Embossed carrier taping and SMD can package simplify integration into automated production flows for high-volume assemblies.
• Predictable loss characteristics: tan δ = 0.14 at 25 V (120 Hz, 20°C) enables clearer thermal and AC-loss budgeting in design.
• RoHS compliant: Conforms to RoHS directives for regulatory compliance in many markets.
