UBT2G470MHD

The UBT2G470MHD is a Nichicon UBT series aluminum electrolytic capacitor in a radial-lead can package, rated 47 µF at 400 V with ±20% capacitance tolerance. It is designed for high-temperature, high-voltage applications and targets automotive electronics where extended endurance and voltage handling are required.

This part combines a compact φ16×30.5 mm can with a 7.5 mm lead spacing and AEC‑Q200 qualification to provide a rugged, service-oriented capacitor solution for systems that must operate up to 125°C with defined endurance performance.

Key Features

• Electrical Performance — 47 µF nominal capacitance with ±20% tolerance and a 400 V rated voltage for high-voltage filtering and energy storage.
• Ripple Current Ratings — Specified ripple capability of 243 mA at 120 Hz (low frequency) and 364.5 mA at 100 kHz (high frequency), enabling effective smoothing under realistic ripple conditions.
• High-Temperature Endurance — Rated for operation from −25°C to 125°C with an endurance (load life) of 2000 hours at 125°C under rated conditions.
• Leakage Current — Specified leakage current of 852 µA, provided per the part’s characterization for predictable bias behavior after voltage application.
• Reliability & Qualification — AEC‑Q200 rated and manufactured by Nichicon, aligning the part with automotive-grade reliability expectations where AEC‑Q200 qualification is required.
• Mechanical & Packaging — Radial lead can (φ16×30.5L) with 7.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Compliance — RoHS compliant, supporting regulatory requirements for restricted substances.

Typical Applications

• Automotive Power Modules — Bulk and decoupling capacitance for high-voltage onboard power modules where 400 V ratings and high-temperature endurance are required.
• Engine Control and Power Electronics — Filtering and smoothing in control modules and power electronics that operate in elevated ambient temperatures up to 125°C.
• On-board Power Supplies — Energy storage and ripple attenuation for DC‑DC converters and on-board supplies within automotive systems.

Unique Advantages

• High-voltage capability: 400 V rating supports higher-voltage rails and modules without series stacking of lower-voltage parts.
• Temperature-rated endurance: Qualified for operation up to 125°C with a specified 2000-hour life at that temperature, providing predictable performance in hot environments.
• AEC‑Q200 qualification: Automotive-grade reliability conformance for designs requiring industry-recognized qualification.
• Defined ripple specifications: Separate low‑ and high‑frequency ripple current ratings (243 mA @120 Hz and 364.5 mA @100 kHz) to aid thermal and lifetime budgeting in power designs.
• Compact radial-lead form: φ16×30.5 mm can with 7.5 mm lead spacing supports straightforward through-hole mounting and mechanical robustness.
• Regulatory compliance: RoHS-compliant construction for use in restricted-substance environments.
