UPA1C682MHD

The UPA1C682MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can, part of Nichicon's UPA series. It delivers 6.8 mF (6800 µF) capacitance at a 16 V rating with low impedance and high ripple-current capability, aimed at power-supply and general-purpose power-filtering applications.

Designed for demanding thermal and ripple environments, this radial-lead capacitor provides long endurance (5000 hours at 105°C), a wide operating temperature range (−55°C to 105°C), and compact dimensions (18 mm diameter × 25 mm length), making it suitable for space-constrained power designs.

Key Features

• Capacitance and Voltage — 6.8 mF (6800 µF) nominal capacitance at a 16 V rated voltage with ±20% tolerance.
• Low Impedance — Rated impedance of 36 mΩ to support lower ESR requirements in power filtering and decoupling.
• High Ripple Current — Low-frequency ripple current 2.4225 A (120 Hz) and high-frequency ripple current 2.85 A (10 kHz) to support switching converter and regulator applications.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.26 (measured at 20°C, 120 Hz) for the part.
• Leakage Current — Specified leakage current of 3264 µA after application of rated voltage and conditions noted in the product data.
• High Temperature Endurance — Rated for 5000 hours at 105°C under the UPA series endurance conditions.
• Robust Temperature Range — Operating from −55°C to 105°C for broad environmental compatibility.
• Compact Radial Can Package — φ18 × 25 mm size with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Compliance — RoHS compliant as specified in the product data.

Typical Applications

• Switching Power Supplies — Bulk filtering and smoothing on input or output rails where high ripple-handling and low impedance are required.
• DC–DC Converters — Energy storage and decoupling for converter stages to stabilize voltage under dynamic loads.
• Industrial Power Modules — Power rail filtering in industrial and control equipment operating across a wide temperature range.

Unique Advantages

• High capacitance in a small can — 6800 µF in a φ18 × 25 mm package reduces board area compared with larger form factors.
• Designed for ripple-intensive applications — Specified LF and HF ripple currents support switching and high-frequency power environments.
• Low impedance for improved transient response — 36 mΩ impedance helps maintain stable rails and reduces voltage droop under load.
• Long high-temperature life — 5000 hours at 105°C offers extended endurance for continuous high-temperature operation.
• Wide operating temperature range — −55°C to 105°C supports installations across harsh ambient conditions.
• Radial lead can for through-hole assembly — Simplifies placement and soldering in mixed-technology boards and legacy layouts.
