UPM1E472MHD

The UPM1E472MHD is a radial-leaded aluminum electrolytic capacitor in Nichicon’s UPM series designed for low impedance and long-life applications. It provides 4700 µF capacitance at a 25 V rating in a compact φ18 × 40 mm can with 7.5 mm lead spacing.

Targeted for demanding environments, this part delivers high ripple-handling capability and extended endurance—backed by a 5000 hour load life at +105°C and AEC-Q200 qualification—making it suitable for systems requiring reliable bulk energy storage and smoothing under elevated temperature and ripple stress.

Key Features

• Capacitance and Tolerance — 4700 µF (4.7 mF) nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 25 V DC rated voltage for mid-voltage power systems.
• Low Impedance — Typical impedance of 18 mΩ helps reduce voltage ripple and improve transient response in power rails.
• High Ripple Current Handling — Low-frequency ripple current of 5.227 A at 120 Hz and high-frequency ripple current of 2.97 A at 200 kHz for robust performance under ripple stress.
• Reliability and Endurance — Endurance of 5000 hours at +105°C under rated DC bias plus rated ripple current; designed for prolonged operation in high-temperature applications.
• Wide Operating Temperature — Specified range from -55°C to +105°C for a broad set of operating environments.
• Dissipation Factor (tan δ) — tan δ of 0.2 measured at 20°C, 120 Hz, 25 V, supporting predictable AC loss characteristics.
• Leakage Current — Measured leakage current of 3525 µA after rated voltage application, consistent with electrolytic capacitor behavior at this capacitance and voltage.
• Package and Mounting — Radial lead, can-style package (φ18 × 40 mm) with 7.5 mm lead spacing (±0.5 mm); available in bulk or bag packing.
• Standards and Compliance — AEC-Q200 qualified and RoHS compliant, supporting use in regulated environments.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and 5000 hour endurance at +105°C make this capacitor suitable for automotive power filtering and energy storage where elevated temperatures and ripple are common.
• Power Supply Filtering — High capacitance combined with low impedance and strong ripple-current ratings support bulk smoothing and decoupling in DC power rails and converters.
• Industrial Controls — The wide -55°C to +105°C operating range and long-life specification support use in industrial systems that require reliable filtering under thermal and electrical stress.

Unique Advantages

• High energy storage in a compact can — 4700 µF in a φ18 × 40 mm package provides significant bulk capacitance where board space is constrained.
• Robust ripple performance — 5.227 A (120 Hz) and 2.97 A (200 kHz) ripple ratings reduce temperature rise and extend system reliability under continuous ripple load.
• Long elevated-temperature life — 5000 hour endurance at +105°C ensures predictable aging and service life in high-temperature applications.
• Low ESR/Impedance — 18 mΩ impedance supports improved transient response and lower power loss in high-current circuits.
• Automotive-ready qualification — AEC-Q200 status provides qualification evidence for vehicle electronics and other demanding system-level requirements.
• Regulatory compliance — RoHS compliant for use in designs that require restricted-substance conformance.
