UVK1J471MHD

The UVK1J471MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UVK series, offered in a radial-lead, standard-type package. With 470 µF capacitance at 63 V and a compact φ12.5 × 20 mm can, it is designed for general-purpose electronic applications that require reliable bulk capacitance in a small footprint.

Key design attributes include high ripple-current capability at both low and high frequencies, a wide operating temperature range (−40 °C to +85 °C), and a specified endurance of 2000 hours at 85 °C—making it suitable for durable power filtering and smoothing in space-constrained assemblies.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20% for predictable bulk energy storage.
• High Ripple-Current Handling — Low-frequency ripple current of 900 mA (120 Hz) and high-frequency ripple current of 1.35 A (10 kHz) to support both mains-related and switching supply ripple suppression.
• Low Loss & Leakage — Specified tanδ of 0.1 (measured at 20 °C, 120 Hz) and measured leakage current of 888.3 µA, enabling efficient energy use and controlled standby drain.
• Endurance & Temperature Range — Rated for 2000 hours at 85 °C and an operating range of −40 °C to +85 °C for stable performance across industrial temperature conditions.
• Compact Radial Package — φ12.5 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole assemblies where board space is limited.
• Regulatory Compliance — RoHS-compliant construction for use in designs targeting regulated markets.

Typical Applications

• General-purpose power filtering — Bulk filtering and smoothing in power supplies and converters that require 470 µF at up to 63 V.
• Switch-mode power supplies — High-frequency ripple current rating supports decoupling at switching frequencies such as 10 kHz.
• Space-constrained through-hole designs — Miniature φ12.5 × 20 mm can suits assemblies where a smaller radial electrolytic is needed.

Unique Advantages

• Compact footprint for reduced board area — Miniature can size (φ12.5 × 20 mm) helps preserve PCB real estate while delivering significant capacitance.
• Dual-frequency ripple capability — Defined ripple current values at 120 Hz and 10 kHz make it suitable for both low-frequency smoothing and high-frequency decoupling.
• Long endurance at elevated temperature — 2000 hours at 85 °C supports sustained performance in continuously powered equipment.
• Controlled leakage and dissipation — Specified leakage current and tanδ give designers predictable loss and standby characteristics.
• Through-hole radial mounting — Standard radial leads and 5 mm lead spacing facilitate robust mechanical connection and easy prototyping/repair.
• RoHS compliance — Meets environmental directive requirements for restricted substances.
