UPA1A472MHD6

The UPA1A472MHD6 is an aluminum electrolytic capacitor in Nichicon’s UPA series engineered for compact, low‑impedance power applications. It is optimized for switching power supplies and general-purpose power electronics where high ripple current handling and a small footprint are required.

Key value comes from its low impedance (52 mΩ), high ripple current capability, RoHS compliance, and a rated operating range that supports -55°C to 105°C with a 5,000‑hour life at 105°C.

Key Features

• Capacitance & Voltage — 4.7 mF (4,700 μF) rated at 10 V for bulk energy storage and smoothing on low‑voltage rails.
• Low Impedance — 52 mΩ impedance for improved filtering performance in high‑frequency switching environments.
• High Ripple Current — Supports 1.98 A at 120 Hz and 2.33 A at 10 kHz to handle ripple and transient currents common in switching supplies.
• Compact Radial Package — Radial can package with L: 20 mm × D: 16 mm and 7.5 mm lead spacing for space‑constrained PCBs and through‑hole assembly.
• Wide Temperature Range — Rated for operation from -55°C to 105°C to suit demanding thermal environments.
• Long High‑Temperature Life — Specified for 5,000 hours at 105°C, supporting long-term reliability in elevated temperature applications.
• Polarized, General‑Purpose Use — Polarized design suitable for typical DC power filtering and bulk decoupling roles.
• RoHS Compliant — Meets RoHS directive (2011/65/EU,(EU)2015/863) for restricted substances compliance.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where low impedance and high ripple current improve regulation and reduce ripple voltage.
• DC–DC Converters — Energy storage and decoupling on converter outputs and intermediate rails in compact power modules.
• General‑Purpose Power Electronics — Bulk capacitance and transient support for industrial and consumer power circuits requiring a compact radial can solution.

Unique Advantages

• Improved ripple handling: Specified ripple currents of 1.98 A (120 Hz) and 2.33 A (10 kHz) enable reliable performance under continuous ripple load.
• Low electrical loss: 52 mΩ impedance reduces AC losses and helps maintain lower ripple voltages in power rails.
• Space‑efficient form factor: 20 mm × 16 mm radial can and 7.5 mm lead spacing provide bulk capacitance in a compact footprint for PCB space savings.
• High‑temperature endurance: 5,000 hours at 105°C supports sustained operation and predictable lifetime in thermally demanding designs.
• Regulatory compliance: RoHS conformity supports use in products targeting restricted‑substance compliance requirements.
