UHW2A471MHD6

The UHW2A471MHD6 from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in the UHW series. It is a radial lead, polarized capacitor specified at 470 µF and 100 V with a compact φ18 × 25 mm can size and 7.5 mm lead spacing.

Designed for general-purpose electronic use, this part delivers high ripple-current capability, long endurance at elevated temperature, and RoHS compliance for use in a range of industrial and commercial electronic systems.

Key Features

• Capacitance & Voltage: 470 µF rated capacitance at 100 V, with a tolerance of ±20% (measured at 120 Hz, 20°C).
• High ripple-current handling: Low-frequency ripple current up to 1.25 A (120 Hz) and high-frequency ripple current up to 2.5 A (10 kHz), enabling robust smoothing under varying ripple conditions.
• Low impedance: Specified impedance of 110 mOhm, supporting lower conduction losses in power circuits.
• Endurance and temperature range: Rated operating temperature from −40°C to +105°C with a life/endurance of 12,000 hours at 105°C.
• Leakage and dissipation: Leakage current listed as 470 µA; tangent of loss angle (tan δ) is 0.08 at 120 Hz, 20°C (rated voltage 100 V).
• Package and mounting: Radial lead can (φ18 × 25 mm) with 7.5 mm lead spacing (±0.5 mm tolerance); available in bulk (no terminal forming) or bag packing for production handling.
• Compliance: RoHS compliant and offered as a mass-production item from the Nichicon UHW series.

Typical Applications

• General-purpose power filtering: Use where 470 µF at 100 V is required for smoothing and energy storage in electronic power rails and intermediate DC links.
• High-ripple environments: Circuits that experience significant AC ripple at low and high frequencies can leverage the specified 1.25 A (120 Hz) and 2.5 A (10 kHz) ripple-current ratings.
• Industrial and commercial electronics: Systems that require long endurance at elevated temperatures (12,000 hours at 105°C) and reliable polarized capacitance in a compact radial-lead package.

Unique Advantages

• Compact high-voltage solution: 470 µF at 100 V in a φ18 × 25 mm can provides a high-capacitance option for space-constrained designs.
• Wide operating temperature: −40°C to +105°C rating and long 12,000-hour endurance at 105°C reduce the need for frequent maintenance or replacement in hot environments.
• High ripple capability: Dual-specification ripple ratings for 120 Hz and 10 kHz give designers quantifiable margins for both low- and high-frequency ripple conditions.
• Measurable electrical performance: Low impedance (110 mOhm), defined tan δ (0.08 at 120 Hz), and specified leakage current (470 µA) allow predictable behavior in power designs.
• Production-ready packaging: Available in bulk or bag packing for straightforward PCB assembly and inventory handling.
• Regulatory compliance: RoHS compliance supports deployment in regulated commercial and industrial product lines.
