UPS1A103MHD

The UPS1A103MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPS series. It is a radial‑lead, polarized device providing 10,000 µF capacitance at 10 V in a compact φ18 × 35.5 mm can.

Designed for general-purpose power applications and switching power supplies, the part delivers high ripple handling, low impedance, a wide operating temperature range (−55 °C to 105 °C), and long endurance (3000 hours at 105 °C).

Key Features

• High Capacitance: 10,000 µF nominal capacitance for bulk energy storage and smoothing in power rails.
• Rated Voltage: 10 V rated voltage suitable for low-voltage power-supply rails.
• Low Impedance: 30 mΩ impedance for improved transient response and reduced power loss.
• High Ripple Current Capability: 2.349 A at 120 Hz and 2.7 A at 10 kHz to support high-frequency switching currents.
• Wide Temperature Range: Operates from −55 °C to 105 °C to withstand harsh thermal environments.
• Long Endurance: 3000 hours life rating at 105 °C for durable, long-term operation under elevated temperature.
• Electrical Characteristics: Capacitance tolerance −20% to +20% and tangent of loss angle (tan δ) 0.38 measured at 20 °C, 120 Hz, 10 V.
• Package & Mounting: Radial lead can, size φ18 × 35.5 mm, lead spacing 7.5 mm; available in bulk (no terminal forming) or bag packing.
• RoHS Compliant: Meets RoHS requirements as indicated in product data.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where high ripple current capability and low impedance are required.
• General-Purpose Power Filtering: Energy storage and decoupling on low-voltage power rails in a variety of electronic equipment.
• Industrial and Harsh-Environment Electronics: Use in systems that require wide operating temperature range (−55 °C to 105 °C) and long endurance at elevated temperature.

Unique Advantages

• Large Bulk Capacitance in a Compact Can: 10,000 µF in a φ18 × 35.5 mm package reduces board area compared with larger-diameter alternatives.
• High Ripple Handling: Rated ripple currents of 2.349 A (120 Hz) and 2.7 A (10 kHz) allow reliable operation with switching supplies and converters.
• Low ESR/Impedance: 30 mΩ impedance supports improved transient performance and lowers heat generation under load.
• Extended High-Temperature Life: 3000 hours at 105 °C provides predictable long-term behavior in elevated-temperature applications.
• Wide Operating Range: −55 °C to 105 °C operation covers demanding environmental conditions.
• Production-Ready Packaging: Available in bulk and bag packing for flexible procurement and assembly workflows.
