UPS1C103MHD

The UPS1C103MHD is a Nichicon UPS series miniature aluminum electrolytic capacitor optimized for switching power supplies and general-purpose power filtering. It delivers 10,000 µF capacitance at a 16 V rating in a compact radial-can package (φ18 × 40 mm) with 7.5 mm lead spacing.

Designed for demanding thermal and ripple environments, this polarized capacitor combines low impedance and high ripple-current capability with wide operating temperature range (−55 °C to 105 °C) and a rated endurance of 3000 hours at 105 °C.

Key Features

• Electrical Performance — 10,000 µF capacitance at 16 V with ±20% tolerance provides bulk energy storage for smoothing and decoupling in power rails.
• Low Impedance — Rated impedance of 27 mΩ supports improved transient response and lower voltage ripple under load.
• High Ripple Current Handling — Low-frequency ripple current 2.871 A (120 Hz) and high-frequency capability 3.3 A (10 kHz) for robust performance across switching frequencies.
• Loss Characteristics — Tangent of loss angle (tan δ) specified as 0.34 at 20 °C, 120 Hz, enabling predictable dissipation behavior in design.
• Reliability & Endurance — Rated life of 3000 hours at 105 °C with defined capacitance, tan δ and leakage current limits after endurance testing.
• Mechanical & Packaging — Radial lead mounting in a compact φ18 × 40 mm can, lead spacing 7.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Wide Temperature Range — Operational from −55 °C to 105 °C for use across a broad set of industrial and electronic equipment environments.
• RoHS Compliant — Manufactured to meet RoHS requirements.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where compact, high-capacitance, low-impedance capacitors are required.
• Industrial Power Modules — Energy storage and ripple suppression in industrial converters and power conditioning modules operating up to 105 °C.
• Backup Power & Hold-up Circuits — Providing stored energy for short-term hold-up and transient support on DC rails.
• General Purpose Power Filtering — Decoupling and bulk capacitance for control electronics, power subsystems, and other general-purpose applications.

Unique Advantages

• High Capacitance in a Miniature Can: 10,000 µF in a φ18 × 40 mm package reduces board area compared with larger cans while retaining bulk energy storage.
• Strong Ripple Performance: Rated ripple currents of 2.871 A (120 Hz) and 3.3 A (10 kHz) allow reliable operation under both low- and high-frequency switching conditions.
• Low ESR/Impedance: 27 mΩ impedance improves power-supply stability and reduces heat generation under load.
• Wide Temperature & Proven Endurance: −55 °C to 105 °C operating range with 3000-hour endurance at 105 °C supports long-term reliability in elevated-temperature environments.
• Flexible Packaging Options: Available in bulk or bag packing to suit manufacturing and procurement preferences.
• Regulatory Compliance: RoHS status confirmed for use in designs requiring restricted substance compliance.
