UWD1C331MCL1GS

The UWD1C331MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's UWD series engineered for surface-mount high-density PCBs. It combines a low-impedance construction with compatibility for 260°C peak reflow soldering, making it suitable for automated SMT assembly lines.

Targeted for automotive and other demanding surface-mount power applications, this capacitor delivers 330 µF at 16 V with operation over a wide temperature range and long endurance for sustained performance in elevated-temperature environments.

Key Features

• Capacitance & Voltage — 330 µF rated capacitance at 16 V for bulk decoupling and energy storage.
• Low Impedance — Specified impedance of 170 mΩ to support lower ripple and improved power-rail stability.
• High-temperature operation — Rated for operation from −55°C to +105°C with endurance of 5000 hours at 105°C.
• 260°C reflow compatibility — Designed for 260°C peak reflow soldering (recommended: 260°C peak for 5 s; 230°C over 60 s; repeat up to 2 times per datasheet guidance).
• Reliability & qualification — AEC-Q200 qualified and RoHS compliant to support regulated and automotive-grade designs.
• Surface-mount package — Chip (radial can SMD) package for high-density PCB layouts; compatible with automatic mounting machines fed with carrier tape.
• Leakage and loss characteristics — Leakage current after 2 minutes ≤ 0.01·C·V or 3 µA (whichever is greater); tan δ (max.) 0.16 at 16 V (measured at 120 Hz, 20°C).
• Low-temperature impedance stability — At 16 V, Z(−25°C)/Z(+20°C) ≤ 2 and Z(−55°C)/Z(+20°C) ≤ 4 (measured at 120 Hz).

Typical Applications

• Automotive control modules — Bulk decoupling and power-rail smoothing in ECU, sensor, and power distribution modules where AEC-Q200 qualification is required.
• DC–DC converters and power supplies — Output filtering and energy storage for surface-mount converter stages operating up to 105°C.
• Compact SMD power subsystems — High-density PCB designs that require a small radial can SMD capacitor compatible with automated tape-fed placement.

Unique Advantages

• Reflow-ready for modern SMT lines: Specified for 260°C peak reflow and carrier-tape mounting, enabling robust automated assembly without special handling.
• Long high-temperature endurance: 5000 hours at 105°C supports long-term stability in elevated-temperature environments common in automotive and industrial electronics.
• Measured low impedance: 170 mΩ impedance reduces ripple and improves transient response on power rails.
• Automotive-grade qualification: AEC-Q200 qualification provides documented reliability for automotive program acceptance and design assurance.
• Controlled leakage and dielectric loss: Defined leakage current and tan δ limits ensure predictable behavior in precision power designs.
• Compact footprint for dense PCBs: 10 × 8 mm (L × D ~1.0 × 0.8 cm) package with recommended land 8.3 × 8.3 mm simplifies placement in constrained layouts.
