UHE2A471MHD6

The UHE2A471MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHE series. It is a radial‑lead, polarized can-type capacitor rated at 470 µF and 100 V, designed for general-purpose applications that require long operational life and low impedance.

Key value propositions include long endurance (10,000 hours at 105°C), low dissipation (tanδ 0.08 at 20°C, 120 Hz), and measurable ripple-current capability at both low and high frequencies—making the part suitable where sustained performance and reliability are required within compact axial profiles (φ18 × 30.5L, lead spacing 7.5 mm).

Key Features

• Capacitance and Voltage — 470 µF capacitance with a 100 V rated voltage and tolerance of -20% to +20%, providing a defined energy storage and voltage handling envelope.
• Long Endurance — Rated for 10,000 hours at 105°C (for 16 to 100 V ratings in UHE series), supporting extended-life designs under elevated temperature conditions.
• Low Loss / Low Impedance — tanδ (DF) = 0.08 measured at 20°C, 120 Hz, and specified impedance of 170 mOhm, enabling efficient operation with reduced thermal dissipation.
• Ripple Current Performance — Low‑frequency ripple current of 1.29 A at 120 Hz and high‑frequency ripple current of 1.72 A at 10 kHz, allowing effective handling of AC ripple across a range of frequencies.
• Leakage Current — Specified leakage current of 470 µA, defined after rated voltage application conditions for predictable standby losses.
• Mechanical Package — Radial lead, can-style package with dimensions φ18 × 30.5L and lead spacing 7.5 mm (lead spacing tolerance 0.5 mm); available in Bulk (no terminal forming) or Bag packing.
• Operating Range and Compliance — Operating temperature range −40°C to +105°C and RoHS compliance for environmental control.

Typical Applications

• General Purpose Electronics — Use where a compact, polarized aluminum electrolytic capacitor with 470 µF/100 V and long life is required for general-purpose circuit designs.
• Power-Handling Modules — Suitable for designs that require defined ripple-current handling (1.29 A at 120 Hz; 1.72 A at 10 kHz) and low impedance for stable operation.
• High-Temperature Environments — Applicable to equipment operating up to 105°C with a 10,000-hour lifetime rating at that temperature for long-term reliability.

Unique Advantages

• Extended Lifetime: 10,000 hours at 105°C for the UHE series ensures prolonged service life in elevated-temperature applications.
• Defined Ripple Capability: Specified low‑ and high‑frequency ripple currents provide predictable performance across frequency ranges important to power designs.
• Low Dissipation Factor: tanδ = 0.08 (20°C, 120 Hz) reduces dielectric losses and helps manage temperature rise in continuous operation.
• Compact Radial Can: φ18 × 30.5L footprint with 7.5 mm lead spacing offers a space-conscious solution for through‑hole assemblies.
• Measured Electrical Parameters: Impedance (170 mOhm) and leakage current (470 µA) are specified for clear design margins and predictable behavior.
• RoHS Compliant: Conforms to RoHS directives for restricted substances compliance in regulated markets.
