UCM1A331MCL1GS

The UCM1A331MCL1GS is a surface-mount aluminum electrolytic capacitor in Nichicon’s UCM series, offering 330 µF nominal capacitance at a 10 V rating. Its chip-type, low-impedance construction and compact radial can SMD package (φ6.3 × 7.7 mm) target compact power decoupling and energy-storage needs in designs that require robust thermal and electrical performance.

Designed for automated assembly with embossed carrier taping and qualified to AEC-Q200, this part is positioned for reliable use across demanding temperature ranges and high-ripple environments where long-term endurance and manufacturability matter.

Key Features

• Capacitance & Voltage  330 µF nominal capacitance with a rated voltage of 10 V and a tolerance of −20% to +20%.
• Low Impedance / Loss  Chip-type, low-impedance design with a maximum tanδ (DF) of 0.19 measured at 20°C, 120 Hz (10 V rating), enabling effective AC performance at typical control frequencies.
• Ripple Current Handling  Low-frequency ripple current of 300 mA (120 Hz) and high-frequency ripple current of 600 mA (10 kHz), supporting smoothing and decoupling under varying switching conditions.
• Leakage & Endurance  Leakage current specified at 33 µA and endurance rated for 2000 hours at 105°C, with capacitance change and tanδ limits defined after the endurance period.
• Temperature Range  Wide operating temperature range from −55°C to +105°C, suitable for thermally demanding environments.
• Package & Assembly  Compact radial can SMD package (φ6.3 × 7.7 mm) with surface-mount land size 6.6 × 6.6 mm, supplied in embossed carrier taping for automatic mounting machines.
• Qualification & Compliance  AEC-Q200 qualified and RoHS compliant, with mass-production availability from Nichicon.

Typical Applications

• Automotive electronic modules  AEC-Q200 qualification and an operating range of −55°C to +105°C make this capacitor suitable for automotive power rails and module designs requiring reliable decoupling and energy buffering.
• Power supply decoupling  330 µF at 10 V combined with high-frequency ripple capability (600 mA at 10 kHz) supports bulk decoupling for compact DC/DC converters and voltage regulators in constrained PCB layouts.
• High-temperature embedded systems  Rated endurance of 2000 hours at 105°C and low leakage current enable use in embedded electronics operating in elevated ambient temperatures.

Unique Advantages

• AEC-Q200 qualification: Enables use in designs requiring automotive-grade component qualifications.
• Compact, automated-assembly ready: Embossed carrier taping and SMD radial can package simplify high-volume pick-and-place manufacturing.
• Balanced AC performance: Low tanδ at 10 V and specified ripple currents across low and high frequencies provide predictable behavior in both line-frequency and switching environments.
• Extended thermal tolerance: −55°C to +105°C operating range and 2000-hour endurance at 105°C provide longevity in thermally stressful applications.
• Stable leakage and reliability specs: Low leakage current (33 µA) and defined post-endurance characteristics support robust power management designs.
