UCK1E382MNS1MS

The UCK1E382MNS1MS is a chip-type, low-impedance aluminum electrolytic capacitor from Nichicon's UCK series designed for surface-mount assembly. It delivers 3.8 mF capacitance at a 25 V rating and is optimized for use in automotive electronics and other demanding environments requiring high-temperature tolerance and automated PCB assembly.

Key value comes from its AEC-Q200 qualification, extended temperature range up to +105°C, and form factor compatible with carrier-tape feeding for automated placement—combining reliability, thermal endurance, and manufacturability for production designs.

Key Features

• Chip-type, low-impedance construction — Designed for reduced ESR to support power-management functions where low impedance is required.
• Electrical ratings — 3.8 mF capacitance, rated voltage 25 V, polarized with ±20% tolerance at 120 Hz, 20°C.
• Ripple-current capability — Rated ripple current of 1.03 A at 120 Hz and 2.06 A at 10 kHz, supporting AC ripple and transient demands.
• High-temperature endurance — Operating temperature range −55°C to +105°C with a lifetime rating of 5000 hours at 105°C.
• Surface-mount, tape-fed packaging — Radial, can-style SMD package compatible with automatic mounting machines fed with carrier tape for high-volume assembly.
• Reliability and compliance — AEC-Q200 qualified and RoHS compliant, with series leakage-current and tan δ performance specified in the UCK datasheet (leakage ≤ 0.01CV or 3 µA after 2 minutes; tan δ max. 0.14 at 25 V, with series allowances).

Typical Applications

• Automotive electronics — Suited for automotive control modules and power systems where AEC-Q200 qualification and high-temperature operation are required.
• Power management modules — Employed in DC power rails and power-supply subsystems that require low impedance and measurable ripple-current handling.
• High-reliability surface-mount assemblies — Fits production lines using carrier-tape placement for compact, automated PCB assembly.

Unique Advantages

• AEC-Q200 qualified: Enables use in automotive-grade designs that require industry-recognized component qualification.
• Extended high-temperature life: 5000 hours at 105°C provides predictable long-term performance in thermally demanding applications.
• High ripple tolerance: Measured ripple-current ratings at both 120 Hz and 10 kHz support a variety of switching and AC conditions.
• Automated assembly ready: Tape-fed surface-mount package simplifies high-volume manufacturing and reduces assembly handling.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for commercial and automotive products.
• Compact SMD can package: Small footprint (L: 1.65 × D: 1.8 cm) for space-constrained board layouts while delivering high capacitance.
