Key Features

• Capacitance and Tolerance 470 µF with tolerance ±20% (–20%~20%), providing predictable bulk energy storage for power rails.
• Rated Voltage 35 V rated voltage suitable for mid-voltage power systems.
• High-Temperature Endurance Specified lifetime of 3000 hours at 135 °C under rated DC bias plus ripple current.
• Automotive Qualification AEC-Q200 rating, supporting use in automotive-grade designs requiring component-level qualification.
• Ripple Current Performance Low-frequency ripple current 891.1 mA (120 Hz) and high-frequency ripple current 1.33 A (10 kHz), enabling effective smoothing under varying switching frequencies.
• Low Impedance and Loss Impedance 58 mΩ and tan δ of 0.12 (measured at 20 °C, 120 Hz) for lower losses and improved transient response.
• Leakage Leakage current specified at 493.5 µA, consistent with electrolytic capacitor behavior after voltage application.
• Package and Mounting Radial can package, diameter φ12.5 mm, length 20 mm, lead spacing 5.0 mm; available in bulk/no terminal forming or bag packing.

Typical Applications

• Automotive Electronics AEC-Q200 qualification and +135 °C endurance make the UBW1V471MHD suitable for in-vehicle power modules and control electronics that require high-temperature stability.
• Power Supply Filtering High ripple current ratings and low impedance provide effective smoothing for DC–DC converters and power rails in demanding environments.
• Embedded and Industrial Systems Long-life specification and broad temperature range support reliable bulk energy storage in industrial control and embedded power systems.

Unique Advantages

• High-temperature capability: Rated for operation to 135 °C with a 3000 h endurance specification, minimizing degradation in hot environments.
• Automotive-grade qualification: AEC-Q200 rating enables use in qualified automotive applications and designs requiring established component qualifications.
• Strong ripple handling: Specified ripple currents at both low and high frequencies reduce stress on upstream regulators and improve system stability.
• Compact radial can: φ12.5 × 20 mm package with 5 mm lead spacing fits space-constrained boards while providing significant capacitance.
• Low impedance and controlled loss: 58 mΩ impedance and tan δ = 0.12 (120 Hz, 20 °C) help reduce power dissipation and improve transient performance.

Why Choose UBW1V471MHD?

The UBW1V471MHD positions itself as a robust bulk capacitor for designs needing high capacitance density, high ripple current capability, and extended operation at elevated temperatures. With AEC-Q200 qualification and a 3000-hour endurance at 135 °C, it is particularly well suited for automotive and other harsh-environment power applications where long-term stability matters.

Its compact radial can and measurable electrical characteristics—470 µF at 35 V, 58 mΩ impedance, and specified leakage—make it straightforward to specify into power supply filters, DC–DC converter output stages, and embedded power subsystems where reliable bulk energy storage is required.
