UBT1C472MHD8

The UBT1C472MHD8 is an aluminum electrolytic capacitor from Nichicon's UBT series, supplied in a radial-lead can package. It delivers 4700 µF capacitance at a 16 V rating with a compact φ18 × 30.5 mm footprint and 7.5 mm lead spacing.

Designed for high-temperature, heavy-duty applications, this capacitor offers long endurance at elevated temperatures and measurable ripple-current capability, making it suitable for demanding electronics environments including automotive systems where AEC-Q200 qualification is required.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance.
• High-temperature Endurance — Rated operating temperature −40°C to +125°C with life/endurance specified to 10000 hours at 125°C for the supported conditions.
• Ripple Current Capability — Low-frequency ripple current 2.191 A (120 Hz) and high-frequency ripple current 3.27 A (100 kHz), supporting DC bias plus rated ripple conditions at elevated temperature.
• Low Impedance — Impedance specified at 18 mΩ, enabling effective smoothing and energy buffering in power circuits.
• Leakage Current — Measured leakage current 2256 µA after application of rated voltage conditions.
• Robust Packaging & Mounting — Radial-lead, can-style package (φ18 × 30.5 mm) with 7.5 mm lead spacing (±0.5 mm); available in Bulk (No Terminal Forming) or Bag Packing.
• Quality & Compliance — AEC-Q200 qualified and RoHS compliant for regulated markets.

Typical Applications

• Automotive electronics — For modules and systems that require capacitors rated for heavy-duty service and AEC-Q200 qualification at elevated temperatures.
• High-temperature power systems — Energy buffering and smoothing where continuous operation at up to +125°C and long endurance (10000 h) are required.
• Power supply filtering under DC bias — Maintaining capacitance and controlled tan δ under rated voltage and ripple-current stress at high temperatures.

Unique Advantages

• High-temperature reliability — Specified endurance up to 10000 hours at 125°C provides predictable lifetime for designs exposed to sustained heat.
• Measurable ripple performance — Distinct low- and high-frequency ripple current ratings (2.191 A at 120 Hz; 3.27 A at 100 kHz) let designers evaluate thermal and ripple handling across operating conditions.
• Low series impedance — 18 mΩ impedance supports effective suppression of voltage ripple and transient response in power rails.
• AEC-Q200 qualification — Meets automotive-grade screening requirements for use in regulated and heavy-duty applications.
• Compact radial-can form factor — φ18 × 30.5 mm size with standard 7.5 mm lead spacing simplifies layout for through-hole assemblies and transformer or power-supply modules.
• RoHS compliant — Conforms to RoHS directives for restricted substances.
