UPS2V470MRD6

The UPS2V470MRD6 is a miniature-sized aluminum electrolytic capacitor from Nichicon’s UPS series, featuring a low-impedance design intended for switching power supplies and general-purpose power filtering. It combines a high rated voltage with a compact radial-can package and radial lead mounting for through-hole applications.

Key product attributes include a 47 µF capacitance at a 350 V rating, wide operating temperature capability, RoHS compliance, and endurance data suitable for designs requiring predictable performance at elevated temperatures.

Key Features

• Electrical Performance — 47 µF capacitance with ±20% tolerance and a 350 V rated voltage; polarized for DC applications.
• Low-Impedance Construction — Specified as a low-impedance type for use in switching power supplies; documented ripple current ratings support AC ripple handling.
• Ripple Current Ratings — Rated ripple current of 200 mA at 120 Hz and 320 mA at 10 kHz, enabling decoupling and smoothing in power circuits.
• Thermal and Reliability — Operating temperature range of −40 °C to +105 °C with a rated lifetime of 3000 hours at 105 °C.
• Package and Mounting — Radial lead, radial-can package with lead spacing of 1.0 cm and physical dimensions L: 3.1 × D: 2.0 cm, suitable for through-hole PCB layouts.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk smoothing and decoupling where low impedance and high voltage handling are required.
• Power Supply Filtering — Output and intermediate bus filtering for power conversion stages that require a polarized electrolytic capacitor.
• Industrial Electronics — General-purpose power sections in industrial control and instrumentation assemblies operating across a wide temperature range.

Unique Advantages

• High Voltage Handling: 350 V rated voltage supports elevated DC-link and high-voltage filter applications.
• Compact Footprint: Miniature radial-can dimensions (3.1 × 2.0 cm) and 1.0 cm lead spacing enable denser PCB layouts.
• Wide Temperature Capability: −40 °C to +105 °C operating range provides flexibility across varied environments.
• Documented Endurance: 3000 hours at 105 °C gives a clear baseline for life-expectancy planning in thermal-stressed designs.
• Ripple Management: Published ripple current ratings at 120 Hz and 10 kHz support design verification for both low- and high-frequency ripple conditions.
• RoHS Compliant: Meets current RoHS directives for environmentally restricted substance requirements.
