UCS2D470MHD

The UCS2D470MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UCS series designed for high ripple current and long-term reliability. It delivers 47 µF capacitance at 200 V in a compact φ12.5 × 20 mm can with 5 mm lead spacing, making it suitable for space‑conscious power designs.

Typical use cases include power supply and ballast applications where sustained ripple handling, wide operating temperature, and extended endurance are required. Key value propositions are elevated ripple capability across frequency bands, a 10000‑hour life rating at 105°C, and RoHS compliance.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, suitable for DC filtering and energy storage in mid‑voltage circuits.
• High Ripple Current — Rated ripple currents of 490 mA at 120 Hz and 980 mA at 100 kHz, with frequency coefficients available (0.50 at 120 Hz, 1.00 at 100 kHz) to guide ripple derating.
• Long Endurance — Designed for 10000 hours of life at 105°C under rated DC bias plus rated ripple current, supporting high‑temperature continuous operation.
• Low Leakage — Specified leakage current of 476 µA (after 1 minute at 20°C), consistent with the UCS series leakage specifications.
• Thermal Range — Operating temperature range from −40°C to +105°C for broad environmental tolerance.
• Compact Radial Can — φ12.5 × 20 mm case (1.25 × 2.00 cm), radial lead mounting with 5 mm lead spacing (±0.5 mm), for through‑hole PCB layouts where board area is constrained.
• Packaging & Availability — Supplied in bulk with no terminal forming and bag packing; product is in mass production and RoHS compliant.

Typical Applications

• Power Supplies — DC filtering and output smoothing in mid‑voltage switch‑mode and linear power supplies where compact size and ripple tolerance are important.
• Ballast Circuits — Energy storage and ripple management in ballast designs as noted for the UCS series.
• General‑Purpose Industrial Electronics — DC decoupling and smoothing in general‑purpose circuits that require a polarized, high‑voltage electrolytic with long endurance.

Unique Advantages

• Balanced Ripple Performance: Dual ripple current ratings for low and high frequencies (490 mA at 120 Hz, 980 mA at 100 kHz) let designers size capacitors with frequency‑specific confidence.
• Extended High‑Temperature Life: 10000 hours at 105°C supports sustained operation in thermally demanding assemblies, reducing replacement frequency.
• Compact Footprint: φ12.5 × 20 mm radial can with 5 mm lead spacing provides high capacitance and voltage in a small through‑hole package for tight PCB layouts.
• Predictable Leakage: Specified leakage current of 476 µA (after 1 minute at 20°C) allows straightforward power‑budgeting and reliability planning.
• Regulatory Compliance: RoHS compliance supports use in designs targeting current environmental standards.
• Production Ready: Mass production status and standard bulk/bag packing simplify procurement and assembly planning for high‑volume builds.

Why Choose UCS2D470MHD?
