UVK2D471MRD

The UVK2D471MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVK series, offering 470 µF capacitance at a 200 V rated voltage. Designed as a miniature-sized radial can, it addresses general-purpose power applications that require bulk capacitance and high-voltage capability in a compact footprint.

Key technical attributes include a wide operating temperature range of −40°C to 85°C, ripple current capability up to 1.495 A (at 10 kHz), specified leakage current, and a 2000-hour endurance rating at 85°C. The part is RoHS compliant and supplied in bulk or bag packing; note the part is listed as End Of Life.

Key Features

• Electrical capacity — 470 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk energy storage and smoothing.
• High voltage rating — Rated voltage of 200 V for applications requiring elevated DC voltage handling.
• Ripple current performance — Low frequency ripple current 1.3 A (120 Hz) and high frequency ripple current 1.495 A (10 kHz), enabling effective AC ripple handling in power circuits.
• Leakage current specified — Leakage current of 3860 µA as provided in the product data for predictable bias current budgeting.
• Reliability and endurance — Endurance specified at 2000 hours when operated at 85°C with rated voltage, with defined limits for capacitance change, tan δ, and leakage recovery after test.
• Compact radial package — Metal can radial-lead package, size φ22 × 40 mm, lead spacing 10 mm (±0.5 mm), suitable for through-hole mounting and straightforward PCB placement.
• Compliance and packing — RoHS compliant; available in Bulk (No Terminal Forming) or Bag Packing to suit assembly or prototype handling.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple handling for power supply smoothing and energy buffering in general-purpose electronic equipment.
• Industrial control — Applicable where 200 V rated capacitors are needed for general-purpose power circuits in industrial electronics.
• Power conversion stages — Suitable for DC link smoothing or reservoir applications in generic power conversion circuits requiring 470 µF at 200 V.

Unique Advantages

• 200 V rating for higher-voltage designs: Supports circuits that require elevated DC voltage capability without changing capacitor topology.
• Substantial capacitance in a compact can: 470 µF in a φ22 × 40 mm radial package conserves board area while delivering bulk energy storage.
• Measured ripple performance: Specified ripple current at both low (1.3 A at 120 Hz) and high (1.495 A at 10 kHz) frequencies allows engineers to size capacitors to expected operating conditions.
• Defined endurance profile: 2000 hours at 85°C with rated voltage provides measurable lifetime expectations for design reliability planning.
• RoHS compliance and packing options: RoHS-compliant construction and bulk or bag packing support assembly and environmental compliance requirements.
