UCW1V331MNL1GS

The UCW1V331MNL1GS is a chip‑type aluminum electrolytic capacitor designed for surface‑mount assembly. It pairs a 330 µF capacitance with a 35 V rated voltage and low impedance characteristics for power decoupling and smoothing in demanding environments.

Built for high‑temperature reliability, this part delivers a long life of 7000 hours at +105 °C, is AEC‑Q200 qualified, and is RoHS compliant—making it suitable for automotive and other high‑reliability electronic applications where space‑efficient SMD components are required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• Low Impedance Performance — Specified impedance of 160 mΩ and low‑impedance temperature range up to +105 °C to help minimize ripple and voltage drop under load.
• High‑Temperature Endurance — Rated load life of 7000 hours at +105 °C, supporting prolonged operation in elevated temperature applications.
• Ripple Current Capability — Handles 425 mA at 120 Hz and 850 mA at 10 kHz, suitable for AC ripple and switching regulator environments.
• Surface‑Mount Chip Package — Chip‑type radial can designed for automatic mounting with carrier tape; surface mount land size 1.03 cm × 1.03 cm and overall footprint 1 cm × 1 cm.
• Reliability & Compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863) for regulated and automotive electronics.
• Operating Range — Specified operating temperature range from −25 °C to +105 °C for use across common automotive temperature environments.

Typical Applications

• Automotive power rails — Bulk decoupling and smoothing on 12 V/24 V vehicle power systems where a 35 V, 330 µF low‑impedance SMD capacitor is required.
• ECU and control modules — Local energy storage and ripple suppression on electronic control units that demand AEC‑Q200 qualified components and long high‑temperature life.
• DC‑DC converters — Input/output filtering for switching regulators, using the specified ripple current ratings and low impedance at high frequency.

Unique Advantages

• Extended high‑temperature life — 7000 hours at +105 °C reduces replacement frequency and supports longevity in harsh thermal environments.
• Measured low impedance — 160 mΩ impedance helps improve voltage stability and reduce losses in power delivery networks.
• Frequency‑capable ripple handling — Separate ripple current specs at 120 Hz and 10 kHz allow confident selection for both line ripple and high‑frequency switching applications.
• SMD‑ready chip form factor — Designed for automatic mounting with carrier tape and a compact 1 cm × 1 cm footprint to save board space and streamline assembly.
• Automotive qualification — AEC‑Q200 qualification supports use in automotive designs that require component‑level reliability evidence.
• Regulatory compliance — RoHS compliance aligns the part with common environmental and regulatory requirements.
