UBT1A472MHD8

The UBT1A472MHD8 is a radial-lead aluminum electrolytic capacitor designed for demanding high-temperature and high-ripple applications. It delivers 4700 µF at 10 V in a compact φ16 × 30.5 mm can with AEC-Q200 qualification and a wide operating temperature range of −40°C to +125°C.

Engineered for automotive and industrial power systems, this capacitor provides high ripple current capability, long endurance (10,000 hours at 125°C), and low impedance for stable bulk energy storage and filtering in power supply and control circuits.

Key Features

• High Capacitance — 4700 µF nominal capacitance (±20% tolerance) for substantial bulk energy storage and smoothing in low-voltage power rails.
• Rated Voltage — 10 V working voltage suitable for low-voltage automotive and industrial electronics.
• High Temperature Endurance — Rated for operation from −40°C to +125°C with a lifetime of 10,000 hours at 125°C, supporting sustained high-temperature use.
• Ripple Current Performance — 1.816 A at 120 Hz (low frequency) and 2.71 A at 100 kHz (high frequency) to handle AC ripple and switching regulator stresses.
• Low Impedance — Typical impedance of 20 mΩ for improved transient response and lower voltage drop under load.
• Leakage and Loss Characteristics — Specified leakage current of 1410 µA and a tangent of loss angle (tan δ) of 0.26 at 20°C, 120 Hz.
• Robust Packaging & Mounting — Radial lead, can package (φ16 × 30.5 mm) with 7.5 mm lead spacing (±0.5 mm); supplied in bulk or bag packing (no terminal forming).
• AEC-Q200 Qualified & RoHS Compliant — Series-level AEC-Q200 qualification and RoHS status included in the product data for regulated designs.

Typical Applications

• Automotive Power Electronics — Bulk capacitance and high ripple handling make this capacitor suitable for control modules, DC–DC converters, and other in-vehicle power circuits that operate at elevated temperatures.
• Switching Power Supplies — Low impedance and high ripple current capability support smoothing and hold-up in low-voltage switching regulators and power converters.
• Industrial Control Systems — Long endurance at 125°C and robust construction enable use in motor drives, PLC power stages, and embedded controllers exposed to high thermal stress.

Unique Advantages

• High energy density in a compact can — 4700 µF in a φ16 × 30.5 mm package reduces board space for bulk storage and filtering.
• Designed for high-temperature operation — 10,000-hour endurance at 125°C provides long-term stability in thermally demanding environments.
• Strong ripple-current tolerance — Separate low- and high-frequency ripple ratings (1.816 A at 120 Hz and 2.71 A at 100 kHz) address both mains and switching converter ripple profiles.
• Reliable electrical performance — Low impedance (20 mΩ) and defined tan δ support predictable behavior in power delivery and decoupling roles.
• Automotive-capable qualification — AEC-Q200 series qualification supports designs targeting automotive electronics where qualification is required.
• Ready for production handling — Bulk and bag packing options simplify procurement and assembly processes for higher-volume manufacturing.
