UCM1K330MCS1GS

The UCM1K330MCS1GS is a chip-type aluminum electrolytic capacitor in a surface-mount can package designed for high-voltage, high-temperature applications. It combines a compact φ6.3 × 7.7 mm footprint with an 80 V rating, making it suitable for power filtering and decoupling where elevated voltage and temperature capability are required.

Built as a low-impedance chip type with embossed carrier taping for automated placement, this capacitor targets applications requiring AEC-Q200 qualification, vibration resistance, and long-term operation up to 105°C.

Key Features

• Electrical: Capacitance & Voltage — 33 µF nominal capacitance with ±20% tolerance at 120 Hz (20°C); rated voltage 80 V.
• Low-loss/Low-impedance — Tangent of loss angle (tan δ) 0.08 measured at 20°C, 120 Hz for the 80 V rating, indicating low dissipation for this class of aluminum electrolytic.
• Ripple performance — Low-frequency ripple current 95 mA at 120 Hz and high-frequency ripple current 190 mA at 10 kHz, supporting steady filtering across a range of switching frequencies.
• Leakage current — Leakage current specified at 26.4 µA after rated voltage is applied under standard test conditions.
• Reliability & Endurance — Rated for 2000 hours at 105°C (endurance condition for the package diameter), with temperature range from -55°C to +105°C.
• Mechanical & Packaging — Surface-mount, radial can (chip type) with package size φ6.3 × 7.7 mm and recommended PCB land 6.6 × 6.6 mm; vibration resistant and supplied in embossed carrier taping for automated mounting.
• Polarized — Polarized aluminum electrolytic design for DC applications.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant.

Typical Applications

• Automotive power electronics — Decoupling and smoothing on 80 V rails where AEC-Q200 qualification and -55°C to +105°C operation are required.
• DC-DC converters — Input/output filtering on higher-voltage converter stages, utilizing the 80 V rating and specified ripple current capability.
• Power management modules — Bulk and local energy storage in compact SMD assemblies, benefiting from the chip-type low-impedance characteristic and taped packaging for automated placement.
• Industrial control electronics — Voltage smoothing and transient suppression in systems exposed to elevated temperature and vibration environments.

Unique Advantages

• Compact high-voltage solution: 33 µF at 80 V in a φ6.3 × 7.7 mm SMD can conserves PCB area while delivering elevated voltage capability.
• Designed for harsh environments: -55°C to +105°C operating range, 2000-hour endurance at 105°C, and vibration resistance target demanding thermal and mechanical conditions.
• Assembly-ready packaging: Embossed carrier taping enables automated pick-and-place for high-volume production.
• Measurable performance metrics: Specified tan δ (0.08 at 80 V, 20°C/120 Hz), leakage current (26.4 µA), and ripple current figures provide clear parameters for thermal and ripple budgeting.
• Industry qualification: AEC-Q200 rating and RoHS compliance support use in regulated markets and designs requiring recognized component-level qualifications.
