UEP1A471MPD

The UEP1A471MPD is a bi-polarized aluminum electrolytic capacitor from Nichicon’s UEP series designed for general-purpose electronic applications. It combines a 470µF capacitance at a 10V rating with a compact radial-can package (φ10×16mm, 5mm lead spacing) for straightforward through-hole assembly.

Engineered for a wide operating temperature range of −55°C to +105°C and a rated endurance of 1000 hours at 105°C, this part targets designs that require stable capacitance and ripple performance across harsh temperature conditions.

Key Features

• Bi-Polarized Construction — Bi-polarized design suitable for applications requiring polarity inversion over the capacitor’s service life.
• Wide Temperature Range — Rated for operation from −55°C to +105°C, supporting use in temperature-challenging environments.
• Capacitance and Tolerance — 470µF capacitance with ±20% tolerance (measured at 120Hz, 20°C) for predictable bulk energy storage.
• Ripple Current Performance — Rated ripple current of 290mA at 120Hz and 435mA at 10kHz, with frequency coefficients applicable for the 100–470µF range.
• Low Leakage — Specified leakage current of 141µA, providing low quiescent loss after rated voltage application.
• Durability and Lifetime — Endurance specified as 1000 hours at 105°C with performance criteria for capacitance change, tan δ, and leakage current.
• Radial Can Package — Compact φ10×16mm aluminum can, radial lead mounting and 5mm lead spacing for easy PCB placement and mechanical stability.
• Regulatory Compliance — RoHS-compliant construction.

Typical Applications

• General Purpose Electronics — For general-purpose circuits that require a bipolar aluminum electrolytic capacitor with 470µF at 10V and wide temperature tolerance.
• Radial Lead Assemblies — Suited to through-hole PCBs and assemblies that accept radial-can capacitors with 5mm lead spacing and φ10×16mm case size.
• High-Temperature Equipment — Appropriate for equipment exposed to elevated ambient temperatures up to +105°C, supported by a 1000-hour rated endurance at that temperature.

Unique Advantages

• Wide operating temperature capability: −55°C to +105°C rating enables reliable performance across broad environmental conditions.
• Bi-polarized design: Allows operation where polarity may invert, supported by the UEP series endurance testing that includes polarity inversion cycles.
• Measured ripple handling: Defined ripple current ratings (290mA at 120Hz, 435mA at 10kHz) and frequency coefficients for the 100–470µF range help predict behavior across frequencies.
• Compact, serviceable package: φ10×16mm radial can with 5mm lead spacing provides a space-efficient solution for through-hole designs.
• Long-term thermal endurance: 1000 hours at 105°C specification supports durability in sustained high-temperature operation.
• RoHS compliance: Meets lead-free regulatory requirements for green assembly processes.
