UCD1K3R3MCL1GS

The UCD1K3R3MCL1GS from Nichicon is a chip-type, low-impedance aluminum electrolytic capacitor designed for surface-mount use on high-density PC boards. It is a polarized SMD can intended for automated assembly and elevated ambient operating conditions.

Engineered for demanding environments, this part combines a 3.3 µF capacitance with an 80 V rating, operation from −55 °C to +105 °C, and AEC-Q200 qualification, making it suitable for automotive and other high-reliability applications that require RoHS-compliant components.

Key Features

• Electrical — Rated capacitance 3.3 µF at 80 V with a tolerance of −20% to +20% and a specified impedance of 5 Ω.
• Temperature & Reliability — Operates across −55 °C to +105 °C and meets endurance requirements with 2000 hours at 105 °C for the specified conditions.
• Ripple Performance — Specified ripple current: 12.5 mA at 120 Hz and 25 mA at 10 kHz, supporting AC ripple handling in appropriate applications.
• Package & Mounting — Chip-type radial can in an SMD package (size L: 5.8 × D: 5 mm) designed for surface mounting; recommended surface-mount land size L: 5.3 × W: 5.3 mm.
• Assembly Compatibility — Applicable to automatic mounting machines fed with carrier tape for high-volume production.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).
• Leakage & Loss Characteristics — Series-level specifications include leakage current limits (after 2 minutes at 20 °C: not more than 0.01 CV or 3 µA, whichever is greater) and defined tan δ limits by rated voltage.

Typical Applications

• Automotive Electronics — Suitable for use in automotive control modules and electronic subsystems that require AEC-Q200-qualified, polarized SMD capacitors capable of operation up to +105 °C.
• High-Density Surface-Mount Assemblies — Designed for placement on compact PCBs where chip-type SMD capacitors and tape-feed assembly are required.
• Industrial and Harsh-Environment Electronics — Useful in industrial control and power electronics that need polarized capacitance with defined endurance at elevated temperatures.

Unique Advantages

• Low-Impedance Design: Specified impedance of 5 Ω supports applications that require reduced AC impedance at the capacitor.
• Wide Temperature Range: Rated from −55 °C to +105 °C, enabling deployment in elevated-temperature environments.
• AEC-Q200 Qualified: Provides a qualification level suited for automotive and other high-reliability designs.
• Automated Assembly Ready: Compatible with carrier-tape fed automatic mounting machines to streamline high-volume production.
• RoHS Compliant: Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863) for environmentally regulated designs.
• Defined Endurance: Specified lifetime of 2000 hours at 105 °C under rated conditions, supporting long-term reliability planning.
