• Rated Voltage — 450 V DC rated voltage for high-voltage applications.
• Loss Tangent (tan δ) — tanδ = 0.25, measured at 20°C and 120 Hz to characterize dielectric loss.
• Ripple Current Ratings — Low-frequency ripple current 115 mA at 120 Hz and high-frequency ripple current 184 mA at 10 kHz (specified values).
• Leakage Current — 184.6 µA leakage current (measured at stated conditions).
• Endurance & Reliability — 2000 hours life at 85°C with performance specified after restoration to 20°C.
• Temperature Range — Operational from -40°C to +85°C.
• Automotive Qualification — Rated to AEC‑Q200 for automotive electronic use.
• Package & Mounting — Radial can SMD, size φ12.5 × 13.5 mm; surface-mount land size L: 1.28 cm × W: 1.28 cm; supplied in embossed carrier taping.
• Polarized — Polarized electrolytic construction for DC applications.

Typical Applications

• Automotive electronic modules — Suited to automotive subsystems that require components meeting AEC‑Q200 qualification.
• High-voltage smoothing and decoupling — Provides 4.7 µF at 450 V for filtering and energy storage on high-voltage rails.
• Power electronics in vehicles — Applicable where specified ripple current and endurance at elevated temperature are required.

Unique Advantages

• High-voltage capability: 450 V rating enables use on elevated DC rails where lower-voltage parts are unsuitable.
• Automotive-grade reliability: AEC‑Q200 rating combined with a 2000 h endurance at 85°C supports automotive qualification workflows.
• Measured performance metrics: Specified tanδ, leakage current, and ripple currents provide concrete data for thermal and loss budgeting.
• Compact SMD form factor: φ12.5 × 13.5 mm radial can SMD package minimizes board footprint while delivering required capacitance.
• Assembly-ready packaging: Embossed carrier taping facilitates automated placement and handling in production lines.

Why Choose UUG2W4R7MNQ1MS?

UUG2W4R7MNQ1MS combines a high 450 V rating and automotive AEC‑Q200 qualification with clearly specified electrical characteristics (capacitance, tanδ, leakage, and ripple currents) to help engineers evaluate performance for high-voltage automotive subsystems. Its compact surface-mount radial can and embossed carrier taping support automated assembly and dense board layouts.

This part is appropriate for designs that require verified endurance at elevated temperature and measurable loss/ripple behavior. Consider it where 4.7 µF at 450 V and automotive-grade reliability are needed, keeping in mind the part is currently End Of Life for procurement planning.
