UCK1V382MNJ1MS

The UCK1V382MNJ1MS is a chip-type, low-impedance aluminum electrolytic capacitor from Nichicon designed for surface-mount assembly. It delivers 3.8 mF capacitance at 35 V in a compact can-style SMD package intended for automated carrier-tape mounting.

Engineered for demanding environments, this unit supports an operating range of -55°C to +105°C, carries AEC-Q200 qualification, and is RoHS compliant—making it suitable for automotive power applications that require high capacitance, robust ripple handling and long-term reliability.

Key Features

• Capacitance & Voltage: 3.8 mF rated capacitance at 35 V, with ±20% tolerance for bulk energy storage and decoupling in power rails.
• Low Impedance Performance: Chip-type, low-impedance construction with ripple current ratings of 1.32 A at 120 Hz and 2.64 A at 10 kHz to support high-frequency and low-frequency ripple handling.
• Temperature & Endurance: Rated for -55°C to +105°C operation with an endurance specification of 5000 hours at 105°C.
• Qualification & Compliance: AEC-Q200 qualified and RoHS compliant for use in regulated automotive and industrial environments.
• Package & Mounting: Surface-mount radial can (SMD) format suitable for automatic mounting with carrier tape; physical size L: 2.15 cm × D: 1.8 cm and recommended land size L: 1.83 cm × W: 1.83 cm.
• Polarized Electrolytic: Polarized aluminum electrolytic construction for bulk energy and smoothing applications.

Typical Applications

• Automotive Power Systems: Bulk smoothing and decoupling on vehicle power rails where AEC-Q200 qualification and high-temperature endurance (105°C) are required.
• ECU and Control Modules: Energy storage and ripple suppression for engine control units and electronic control modules that demand compact SMD capacitors with high capacitance.
• Infotainment & Body Electronics: Power supply stabilization and transient suppression in infotainment, telematics, and body electronics subsystems.

Unique Advantages

• High Capacitance in an SMD Can: 3.8 mF capacitance in a compact chip-type can enables significant bulk storage without through-hole assembly.
• Designed for Automated Assembly: Compatible with carrier-tape feeding to support high-volume surface-mount placement.
• Robust Ripple Handling: Specified ripple currents at both low and high frequencies (1.32 A at 120 Hz; 2.64 A at 10 kHz) support mixed-frequency power noise environments.
• Automotive-Grade Qualification: AEC-Q200 rating provides documented reliability requirements suitable for automotive applications.
• Wide Operating Temperature: -55°C to +105°C range supports operation across typical automotive thermal extremes.
• Long Life at Elevated Temperature: 5000 hours endurance at 105°C for sustained performance in high-temperature assemblies.
