UVK2E471MRD

The UVK2E471MRD is a radial lead aluminum electrolytic capacitor from Nichicon’s UVK series, offering 470 µF capacitance at a 250 V rated voltage in a compact φ22 × 50 mm can. It is designed for general-purpose electronic equipment that requires polarized bulk capacitance with defined ripple-handling and endurance characteristics.

Key attributes include a –40 °C to 85 °C operating range, a 2000-hour endurance rating at 85 °C, and measured loss tangent and leakage values specified at 120 Hz and 20 °C to support reliable performance in sustained operating conditions.

Key Features

• Capacitance & Voltage — 470 µF capacitance rated at 250 V to deliver substantial bulk energy storage for general-purpose applications.
• Tolerance — Capacitance tolerance of ±20% (–20% to +20%) at 120 Hz, 20 °C.
• Package & Mounting — Radial lead, can-style package (φ22 × 50 mm) with 10 mm lead spacing (±0.5 mm), supplied as Bulk (No Terminal Forming) / Bag Packing.
• Temperature & Endurance — Operating temperature range from –40 °C to 85 °C with a rated endurance of 2000 hours at 85 °C.
• Ripple Current Performance — Low-frequency ripple current 1.4 A at 120 Hz and high-frequency ripple current 1.61 A at 10 kHz, supporting applications with AC ripple stresses.
• Electrical Losses & Leakage — Tangent of loss angle (tan δ) 0.20 (measured at 20 °C, 120 Hz) and leakage current specified at 4800 µA for this part.
• Polarized Design — Polar aluminum electrolytic construction for conventional polarized energy storage and filtering functions.
• Lifecycle Status — Product status: End Of Life.

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance and ripple handling where a 470 µF / 250 V radial electrolytic is required.
• Power filtering and smoothing — Sized to support DC link and filtering roles in general-purpose designs with specified ripple current capability.
• Industrial and commercial electronics — Applicable where a polarized, radial lead capacitor with defined endurance (2000 h at 85 °C) is acceptable.

Unique Advantages

• High voltage rating: 250 V rating enables use in higher-voltage general-purpose circuits requiring substantial capacitance.
• Compact radial can: φ22 × 50 mm form factor and standard 10 mm lead spacing simplify layout for through-hole assemblies.
• Defined ripple capability: 1.4 A at 120 Hz and 1.61 A at 10 kHz give clear limits for thermal and ripple budgeting in designs.
• Measured loss and leakage specs: tan δ = 0.20 (20 °C, 120 Hz) and leakage current = 4800 µA provide verifiable electrical characteristics for selection and modelling.
• Endurance-rated: 2000 hours at 85 °C supports lifecycle planning for products operating in elevated-temperature environments.
• Packaging flexibility: Available in bulk/no terminal forming and bag packing to match assembly and handling preferences.

Why Choose UVK2E471MRD?
