UHE2A470MPD

The UHE2A470MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can. It delivers 47 µF of polarized capacitance at a 100 V rating in a compact φ10 × 12.5 mm package with 5 mm lead spacing.

Designed for general-purpose electronic applications that require long operational life and stable performance, this UHE series part combines low loss, low impedance and specified ripple handling for reliable DC bias and filtering use within the –40°C to 105°C operating range.

Key Features

• Electrical Performance — 47 µF capacitance with ±20% tolerance and a rated voltage of 100 V, suitable for circuits requiring polarized energy storage in a radial-lead format.
• Low Loss / Low Impedance — tanδ (DF) 0.08 measured at 20°C, 120 Hz and an impedance of 1.8 Ω, supporting efficient filtering and reduced heat generation under AC ripple conditions.
• Ripple Current Capability — Low-frequency ripple current of 227.5 mA at 120 Hz and high-frequency ripple current of 325 mA at 10 kHz, enabling stable operation across common ripple environments.
• Leakage and Reliability — Specified leakage current of 47 µA and long endurance rating of 7000 hours at 105°C (for the specified case size and rated voltage).
• Mechanical & Packaging — Miniature φ10 × 12.5 mm can with 5 mm lead spacing (±0.5 mm) in a radial-lead configuration; available in bulk (no terminal forming) and bag packing.
• Wide Temperature Range & Compliance — Rated for –40°C to 105°C and RoHS compliant.

Typical Applications

• General Purpose Electronics — Use where a compact, polarized aluminum electrolytic is required for energy storage, decoupling or filtering at up to 100 V.
• Power Modules and Supplies — Suitable for DC bias environments where long life and defined ripple handling (at 120 Hz and higher frequencies) are required.
• Embedded and Industrial Equipment — Miniature radial-lead form factor fits space-constrained boards while providing stable capacitance across –40°C to 105°C operating range.

Unique Advantages

• 100 V Rated Voltage — Enables use in higher-voltage DC circuits while maintaining a compact footprint.
• Long Endurance — 7000 hours at 105°C supports extended field life in demanding thermal environments.
• Measured Low Loss — tanδ 0.08 at 120 Hz (20°C) indicates lower dissipation under AC conditions, aiding thermal stability.
• Frequency-aware Ripple Performance — Specified ripple currents at both low and high frequencies (227.5 mA at 120 Hz; 325 mA at 10 kHz) provide clarity for design margining across common ripple spectra.
• Compact Radial-lead Package — φ10 × 12.5 mm can with 5 mm lead spacing simplifies through-hole assembly in space-limited designs.
• RoHS Compliant — Meets regulatory material requirements for restricted substances.
