UPA1C472MHD

The UPA1C472MHD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon's UPA series, engineered for high reliability in power applications. It provides 4700 µF capacitance at a 16 V rating with low impedance and rated ripple-current characteristics suited to switching power supplies and other general-purpose power circuits.

Designed for through-hole mounting, the part combines compact dimensions (φ16 × 25 mm) with a wide operating temperature range and extended endurance for robust operation in demanding thermal and ripple-current conditions.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance at a 16 V rated voltage with capacitance tolerance of −20% to +20%.
• Low Impedance — Impedance of 38 mΩ, helping reduce voltage ripple in power rails.
• High Ripple Current — Rated ripple current of 2.346 A at 120 Hz (low frequency) and 2.76 A at 10 kHz (high frequency), measured under the stated conditions.
• Loss & Leakage — Tangent of loss angle (tan δ) specified as 0.22 (measured at 20°C, 120 Hz, 16 V) and leakage current listed at 2256 µA.
• Temperature & Endurance — Operating range from −55°C to +105°C with a rated endurance of 5000 hours at 105°C.
• Package & Mounting — Radial lead can (φ16 × 25 mm), lead spacing 7.5 mm with ±0.5 mm tolerance; available in bulk (no terminal forming) or bag packing.
• Compliance & Availability — RoHS compliant and listed as mass production status.

Typical Applications

• Switching Power Supplies — Miniature, low-impedance construction and high rated ripple current make this capacitor suitable for switching power supply designs where reliable ripple handling is required.
• General-Purpose Power Circuits — Specified as a general purpose component for power applications that require long endurance at elevated temperatures.
• High-Ripple Power Networks — Use where measured ripple-current performance (2.346 A at 120 Hz, 2.76 A at 10 kHz) and low impedance are needed to manage AC stress on the capacitor.

Unique Advantages

• Compact, high-capacity package: 4700 µF in a φ16 × 25 mm can reduces board area compared to larger through-hole options while providing substantial capacitance.
• Designed for ripple-heavy environments: Specified ripple-current values at both low and high frequencies support reliable operation under AC stress.
• Low impedance for improved power performance: 38 mΩ impedance helps minimize voltage drop and ripple on power rails.
• High-temperature endurance: Rated to operate between −55°C and +105°C with 5000 hours endurance at 105°C for longer service life in thermally demanding designs.
• Through-hole mounting and standard lead spacing: Radial lead format with 7.5 mm spacing (±0.5 mm) eases PCB layout and assembly for traditional power electronics manufacturing.
• RoHS compliant and mass-production ready: Supports environmental regulatory requirements and consistent supply for production designs.
