UHW1K470MPD

The UHW1K470MPD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in the UHW series, configured as a radial lead (can) type. With a 47 µF capacitance at an 80 V rating and a compact φ8 × 11.5 mm package, it targets general-purpose electronic designs that require elevated voltage support, long endurance and strong ripple-current handling.

Its key value lies in combining high ripple current capability and low high-frequency impedance with a long rated life of 10,000 hours at 105 °C, making it suitable for demanding power-filtering and general-purpose applications in industrial and electronic equipment.

Key Features

• Electrical Performance — 47 µF capacitance with ±20% tolerance and rated voltage of 80 V provides reliable bulk capacitance for higher-voltage circuits.
• Low Loss / High Frequency — tanδ (loss tangent) of 0.09 (20 °C, 120 Hz) and a specified impedance of 1.3 Ω support lower dissipation and improved performance at higher frequencies.
• High Ripple Current Capability — Rated low-frequency ripple current of 380 mA (120 Hz) and high-frequency ripple current of 950 mA (10 kHz) address AC ripple and switching noise in power rails.
• Reliability and Endurance — Rated for 10,000 hours at 105 °C, with leakage current specified at 37.6 µA, supporting long-term operation under elevated temperature and load.
• Compact Radial Lead Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial lead mounting simplifies through-hole assembly and mechanical placement.
• Wide Operating Temperature — Specified for operation from −40 °C to +105 °C to suit a broad range of environmental conditions.
• Environmentally Compliant — RoHS compliant packaging and materials.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to support different production and prototyping workflows.

Typical Applications

• General-purpose power filtering — Use as bulk capacitance or smoothing in higher-voltage circuits where 80 V rating and high ripple current capability are required.
• Switching power supplies and DC–DC converters — Provides ripple-current handling and low high-frequency impedance to support switching-regulator output filtering.
• Industrial and instrumentation electronics — Compact, high-reliability capacitor for general-purpose energy storage and decoupling in industrial control and measurement equipment.

Unique Advantages

• High-voltage capability: 80 V rating enables use in circuits that exceed standard low-voltage electrolytic ranges without changing capacitor family.
• Compact footprint with radial leads: φ8 × 11.5 mm can and 3.5 mm lead spacing provide a small, easy-to-place through-hole option for denser PCBs.
• Strong ripple performance: 380 mA (120 Hz) and 950 mA (10 kHz) ripple ratings reduce the need for paralleling or oversized components in many designs.
• Long high-temperature life: 10,000 hours rated at 105 °C supports designs that require extended operational lifetime under heat and load.
• Low leakage and controlled loss: Specified leakage current (37.6 µA) and tanδ (0.09 at 120 Hz) help maintain efficiency and predictable behavior in DC circuits.
