ULT2W3R3MNL1GS

The ULT2W3R3MNL1GS is a chip‑type aluminum electrolytic capacitor in a surface‑mount radial can package designed for high‑voltage, high‑temperature applications. It delivers 3.3 µF capacitance at a 450 V rating with a compact footprint and is built for automated assembly using carrier tape.

Targeted for demanding environments, this capacitor offers long high‑temperature endurance and industry qualification to support robust system designs in automotive and high‑temperature power electronics.

Key Features

• Electrical Performance — 3.3 µF nominal capacitance with ±20% tolerance, rated for 450 V operation and a tan δ (loss tangent) max of 0.30 at the 450 V rating (measured at 120 Hz, 20°C).
• High‑Temperature Endurance — Load life specified at 2000 hours at +125°C; after this test the capacitance remains within ±30% of the initial value and leakage current stays within the initial specified limit.
• Leakage Current Specification — Leakage defined by the series formula 0.04CV + 100 μA (1 minute at 20°C) for 160–450 V units; for this 3.3 µF, 450 V part the calculated upper limit is approximately 159 μA (1 minute at 20°C).
• Ripple Current — Rated ripple handling of 20 mA at 120 Hz and 30 mA at 10 kHz, supporting AC ripple in power circuits.
• Temperature Range — Guaranteed operation from −40°C to +125°C, suitable for elevated ambient designs.
• AEC‑Q200 Qualified & RoHS Compliant — Meets AEC‑Q200 qualification and is compliant with RoHS directives for environmental and reliability requirements in regulated markets.
• Assembly‑Ready Surface‑Mount Package — Radial, can‑style SMD chip package sized L: 1 × D: 0.8 cm with a recommended land pattern of 8.3 × 8.3 mm, and is applicable to automatic mounting machines using carrier tape.

Typical Applications

• Automotive Power Modules — AEC‑Q200 qualification and high‑temperature endurance make this capacitor suited for onboard power electronics and auxiliary power systems.
• High‑Temperature Power Electronics — Rated for continuous operation to +125°C and 450 V, appropriate for DC link, snubber, or filter duties in elevated‑temperature environments.
• Compact Industrial Power Supplies — Low profile and small footprint provide a high‑voltage capacitance option where board space is constrained and automated assembly is required.

Unique Advantages

• High‑Voltage Capability: 450 V rating enables use in higher‑voltage DC systems without series stacking.
• Extended High‑Temperature Life: 2000 hours at +125°C provides measurable endurance for designs exposed to sustained elevated temperatures.
• Automated Assembly Compatible: Carrier‑tape compatibility and SMD can package streamline pick‑and‑place processing and reduce manual handling.
• Automotive‑Grade Reliability: AEC‑Q200 qualification supports qualification needs for transportation and other safety‑critical platforms.
• Compact Footprint: Small L × D dimensions and defined land pattern help minimize PCB area for high‑voltage capacitance requirements.
• Regulatory Compliance: RoHS conformity simplifies selection for regulated markets and designs.
