UPT2D471MRD

The UPT2D471MRD is an aluminum electrolytic capacitor from Nichicon’s UPT series, designed as a radial-lead, can-style component that delivers 470 µF at 200 V. It targets general-purpose power circuits and applications that require compact bulk capacitance with elevated ripple-handling capability.

Key value propositions include high ripple current capability, a long endurance rating at elevated temperature, RoHS compliance, and a compact radial package suitable for through-hole assemblies.

Key Features

• Capacitance & Voltage: 470 µF nominal capacitance with a rated voltage of 200 V and a tolerance of ±20%, providing predictable bulk energy storage for DC circuits.
• High ripple current capability: Rated ripple current of 1.2 A at 120 Hz and 1.92 A at 10 kHz, supporting circuits with significant AC ripple on DC rails.
• Frequency-dependent ripple allowance: Frequency coefficient increases with frequency (e.g., 1.00 at 120 Hz up to 1.60 at 10 kHz or more), enabling higher allowed ripple at higher ripple frequencies.
• Long life at elevated temperature: Endurance specified as 5000 hours at 105 °C under D.C. bias plus rated ripple; capacitance change remains within ±20% after the test.
• Operating temperature range: –40 °C to +105 °C for broad environmental tolerance in power assemblies.
• Radial lead, can package: Through-hole radial lead mounting with 10 mm lead spacing and compact dimensions (L: 4 cm × D: 2.2 cm) for straightforward PCB placement and mechanical stability.
• Electrical quality: Loss tangent (tan δ) ≤ 0.12 at 200 V, 120 Hz, 20 °C, and leakage current specified per datasheet (≤ 0.06CV + 10 µA after 2 minutes at 20 °C).
• Regulatory status: RoHS compliant.

Typical Applications

• Ballast and lamp control circuits — Suited for ballast applications where high ripple current capability is required to withstand alternating loads.
• General-purpose power supplies — Bulk filtering and energy storage in DC power rails for industrial or consumer equipment that require through-hole components.
• High-temperature power assemblies — Designs that demand long-term operation at elevated temperature, leveraging the 5000 hour endurance at 105 °C.

Unique Advantages

• High ripple tolerance: Provides specified ripple current at both low and high frequencies, and benefits from a frequency coefficient that increases allowable ripple at higher frequencies.
• Compact through-hole form factor: Radial can package with compact dimensions simplifies mechanical mounting and replacement in existing through-hole designs.
• Long-term reliability at temperature: Endurance tested for 5000 hours at 105 °C ensures maintained capacitance and leakage performance after prolonged thermal stress.
• Clear electrical specifications: Defined tan δ and leakage current criteria (0.06CV+10 µA after 2 minutes at 20 °C) enable deterministic selection for power designs.
• Regulatory compliance: RoHS status supports environmentally constrained product development and procurement.
