UVY2W470MHD

The UVY2W470MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UVY series, rated for 450 V with a nominal capacitance of 47 µF. It is a polarized, general-purpose high-voltage capacitor designed for applications that require compact size, long endurance at elevated temperature, and defined ripple handling at both low and high frequencies.

Key value propositions include a 450 V rating, a wide operating temperature range up to 105 °C, measurable ripple current performance at 120 Hz and 10 kHz, and RoHS compliance—packaged for bulk or bag handling and available in mass production.

Key Features

• High Voltage Rating — Rated voltage of 450 V suitable for higher-voltage DC filtering and energy storage in general-purpose circuits.
• Capacitance and Tolerance — 47 µF nominal capacitance with ±20% tolerance for predictable bulk capacitance and decoupling performance.
• Loss Characteristics — Tangent of loss angle (tan δ) = 0.25 measured at 20 °C, 120 Hz, supporting predictable dissipation behavior.
• Ripple Current Performance — Low-frequency ripple current 155 mA at 120 Hz and high-frequency ripple current 248 mA at 10 kHz for AC ripple handling across common frequency bands.
• Endurance and Temperature — Rated life of 2000 hours at 105 °C and operating temperature range from −25 °C to 105 °C for sustained use in elevated-temperature environments.
• Compact Radial Can Package — Case size φ16 × 30.5 mm with 7.5 mm lead spacing (±0.5 mm tolerance) and radial lead mounting for through-hole assemblies; available in bulk (no terminal forming) or bag packing.
• Leakage Current — Specified leakage current: 946 µA for immediate verification during incoming inspection or design margining.
• Regulatory — RoHS compliant for use in designs requiring restricted substances conformance.

Typical Applications

• High-Voltage Power Supplies — Filtering and smoothing in DC bus and high-voltage stages where a 450 V rated capacitor and 47 µF capacitance are required.
• Industrial Power Electronics — Bulk decoupling and energy buffering in converters and other general-purpose industrial circuits that operate within −25 °C to 105 °C.
• Frequency-Dependent Ripple Mitigation — AC ripple suppression across low and high frequency bands, supported by specified ripple current at 120 Hz and 10 kHz.

Unique Advantages

• High voltage capability: 450 V rating enables use in higher-voltage circuits without series stacking or complex arrangements.
• Predictable thermal endurance: 2000 hours at 105 °C gives designers a defined lifetime metric for thermal reliability planning.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 10 kHz provide measurable performance for both mains-frequency and switching-frequency applications.
• Compact radial format: φ16 × 30.5 mm can size with 7.5 mm lead spacing simplifies through-hole PCB placement while keeping board footprint moderate.
• Traceable leakage spec: Stated leakage current of 946 µA supports predictable standby and leakage budgeting in power designs.
• RoHS compliant and production-ready: Environmentally compliant construction and mass-production status support volume procurement and manufacturing readiness.
