UHW2A471MHD

The UHW2A471MHD is a high-reliability, miniature aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power applications. It delivers 470 µF capacitance at a 100 V rating with a compact φ12.5 × 40 mm can and 5 mm lead spacing, offering a balance of high ripple capability and long-term endurance.

Engineered for elevated temperature operation and extended life, this part supports designs that require sustained ripple performance and stability across –40°C to 105°C environments.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 100 V rated voltage and tolerance of −20% to +20% for bulk energy storage and DC bus support.
• High Ripple Current — Rated ripple current of 1.43 A at 120 Hz and 2.86 A at 10 kHz, enabling effective smoothing under continuous AC ripple loads.
• Low Loss / Low Impedance — Specified impedance of 95 mΩ and tan δ of 0.08 (20°C, 120 Hz), supporting efficient filtering with reduced dissipation.
• Long Endurance — 12,000 hours rated life at 105°C, maintaining capacitance within ±25% (series endurance specification) and leakage current at or below initial specified values after endurance testing.
• Robust Environmental Range — Operating temperature from −40°C to 105°C for reliable performance across industrial temperature extremes.
• Radial Lead, Compact Package — φ12.5 × 40 mm can with 5 mm lead spacing (±0.5 mm); available bulk (no terminal forming) or bag packing to suit assembly needs.
• Leakage Current — Rated leakage current of 470 µA, measured after application of rated voltage, supporting predictable standby behavior.
• RoHS Compliant — Manufactured to meet RoHS directive requirements as noted in the product series documentation.

Typical Applications

• General-purpose Power Filtering — Use for DC bus smoothing and bulk energy storage where 470 µF at 100 V is required.
• Power Supply Decoupling — Suitable for decoupling in power supplies and converters that require sustained ripple handling up to several amps.
• Industrial Electronics — Applicable in control and instrumentation equipment that operate across −40°C to 105°C and need long endurance components.

Unique Advantages

• High Ripple Capability: Delivers 1.43 A (120 Hz) and 2.86 A (10 kHz) ripple current ratings to reduce heat buildup and maintain stability under AC-loaded conditions.
• Compact Miniature Can: φ12.5 × 40 mm size provides a small footprint for designs constrained by board space while preserving capacitance and voltage rating.
• Low Impedance and Loss: 95 mΩ impedance and tan δ of 0.08 (20°C, 120 Hz) translate to lower ESR-related losses and improved filtering performance.
• Extended High‑Temperature Life: 12,000 hours endurance at 105°C for long-term reliability in thermally stressed applications.
• Clear Assembly Options: Supplied in bulk (no terminal forming) or bag packing to accommodate different manufacturing workflows.
• Predictable Leakage Behavior: Specified leakage current (470 µA) supports predictable power-up and standby characteristics.
