UWD1V330MCL1GS

The UWD1V330MCL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UWD series, specified for surface-mount assembly on high-density PC boards. It combines 33 µF capacitance at 35 V with low impedance characteristics and is designed to withstand elevated operating temperatures up to +105°C.

Engineered for automated SMD production, the part supports carrier-tape mounting and reflow soldering profiles up to a 260°C peak. It is RoHS compliant and AEC-Q200 qualified for applications requiring recognized component-level reliability.

Key Features

• Electrical performance — 33 µF nominal capacitance at 35 V with ±20% tolerance and polarization appropriate for typical DC filtering and decoupling duties.
• Low impedance — Characteristic impedance specified at 440 mOhm, with ripple current ratings of 115 mA at 120 Hz and 230 mA at 10 kHz for effective ripple suppression.
• High-temperature operation — Rated for operation from −55°C to +105°C with endurance defined as 2000 hours at 105°C for this size (φD = 6.3 mm).
• Reflow and assembly compatibility — Chip-type package designed for automatic mounting by carrier tape and compatible with 260°C peak reflow (recommended: 260°C peak for 5 seconds; 230°C over 60 seconds as noted).
• Compact SMD can package — Size dimensions L: 5.8 × D: 6.3 mm with recommended land pattern 6.6 × 6.6 mm, enabling dense board layouts.
• Leakage and loss characteristics — Leakage current limited to ≤0.01 CV or 3 µA (whichever is greater) after 2 minutes at 20°C; tan δ specified for 35 V at 120 Hz (max. 0.12) for predictable AC behavior.
• Compliance and qualification — RoHS compliant and AEC-Q200 qualified for designs requiring standardized component qualification.

Typical Applications

• Automotive electronics — Smoothing and decoupling in ECUs, power modules and other vehicle electronics where AEC-Q200 qualification and +105°C operation are required.
• Power supply filtering — Bulk and output filtering for DC-DC converters and voltage regulators on compact SMD boards.
• High-density SMD assemblies — On-board decoupling in space-constrained designs that require carrier-tape compatible, reflow-capable capacitors.
• Industrial control modules — Power conditioning and ripple suppression in industrial electronics operating across a wide temperature range.

Unique Advantages

• Designed for elevated-temperature use — Rated to +105°C with defined endurance (2000 hours at 105°C for this diameter), providing predictable lifetime behavior under thermal stress.
• Reflow-capable for modern assembly — Specified for 260°C peak reflow conditions, simplifying integration into lead‑free SMT production flows.
• Low-impedance performance — 440 mOhm impedance and defined ripple current ratings deliver effective noise and ripple suppression in power circuits.
• AEC-Q200 qualification — Meets industry qualification for applications that require verified component-level reliability.
• Compact SMD form factor — Small L × D footprint and recommended land size support high-density PCB layouts while remaining compatible with automated pick-and-place.
