UWT1A331MNL1GS

The UWT1A331MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UWT series, specified for surface-mount assembly on high-density PC boards. With a rated capacitance of 330 µF and a 10 V rating, this polarized SMD can is designed for automated tape-fed placement and RoHS-compliant production.

Key attributes include a wide operating temperature range of −55 to +105°C, AEC-Q200 qualification, and endurance rated to 1000 hours at 105°C, making it suitable for designs that require robust thermal performance and supply filtering in demanding environments.

Key Features

• Capacitance and Voltage — 330 µF nominal capacitance at a 10 V rated voltage with ±20% tolerance, suitable for bulk decoupling and energy storage in compact circuits.
• Wide Temperature Range — Specified for −55 to +105°C operation to support designs exposed to wide ambient and thermal conditions.
• Automotive-Grade Reliability — AEC-Q200 qualified and endurance tested for 1000 hours at 105°C, supporting reliability requirements for vehicle electronics.
• Surface-Mount, Tape-Feed Compatible — Chip-type SMD can designed for automatic mounting machines fed with carrier tape, enabling high-density PCB assembly.
• Leakage and Loss Characteristics — Datasheet specifies leakage current limits (≤ 0.01CV or 3 µA after 2 minutes at 20°C) and tan δ performance per rated voltage for predictable electrical behavior.
• Ripple Current Performance — Rated ripple handling of 195 mA at 120 Hz and 292.5 mA at 10 kHz to support smoothing and decoupling in power rail applications.
• Compact SMD Can — Package dimensions L: 1.0 × D: 0.8 cm with recommended land pattern 8.3 × 8.3 mm for space-constrained board layouts.
• RoHS Compliant — Meets RoHS directive requirements for lead-free production and regulatory compliance.

Typical Applications

• Automotive Electronics — Suitable for electronic control modules and subsystems that require AEC-Q200 qualification and operation across −55 to +105°C.
• High-Density PCB Assemblies — Designed for surface mounting and tape-fed automated placement in compact, densely populated boards.
• Power Filtering and Decoupling — Used where 330 µF bulk capacitance and specified ripple current handling are needed to stabilize DC rails.
• RoHS-Compliant Systems — Fits designs that require lead-free components for regulatory compliance and environmental considerations.

Unique Advantages

• Wide operating temperature span — −55 to +105°C rating enables deployment in environments with extreme thermal variation.
• AEC-Q200 qualification — Provides an established reliability baseline for automotive and similarly demanding applications.
• Tape-feed SMD packaging — Simplifies high-volume automated assembly and reduces handling variability on production lines.
• Long endurance at elevated temperature — Rated for 1000 hours at 105°C to support long-term stable performance under thermal stress.
• Measurable ripple and leakage specs — Published ripple current and leakage limits allow predictable power-supply design and margining.
• Compact footprint — Small can package and defined land pattern help save board space while delivering significant capacitance.
