UPM1A103MHD

The UPM1A103MHD is a radial-lead aluminum electrolytic capacitor offering 10,000 µF capacitance at a 10 V rating in a φ18 × 40 mm can. It is part of Nichicon's UPM series, designed for low impedance and long life under elevated-temperature conditions.

Targeted at automotive electronics and other high-reliability markets, this capacitor delivers high ripple-current capability and extended endurance—rated for 5,000 hours at 105°C—while meeting AEC-Q200 and RoHS requirements.

Key Features

• High capacitance: 10,000 µF nominal capacitance provides substantial bulk energy storage for smoothing and decoupling in power systems.
• Rated voltage: 10 V rated voltage suitable for low-voltage power rails.
• Low impedance: Impedance specified at 17 mΩ, supporting high current transients and low-loss filtering.
• High ripple-current capability: Low-frequency ripple current 9.474 A (120 Hz) and high-frequency ripple current 2.97 A (200 kHz) to handle demanding power conditioning.
• Long endurance at elevated temperature: Rated life 5,000 hours at 105°C under specified load conditions for extended reliability in thermally stressed environments.
• Wide operating temperature: −55°C to +105°C to cover a broad range of environmental conditions.
• Radial-lead, compact can: φ18 × 40 mm package with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and robust mechanical connection.
• Electrical loss and leakage: Dissipation factor (tan δ) 0.37 measured at 20°C, 120 Hz, 10 V; leakage current specified at 3000 µA.
• Quality and compliance: AEC-Q200 qualified and RoHS compliant, aligned with automotive reliability expectations.
• Packaging options: Supplied in Bulk (no terminal forming) or Bag packing for production handling.

Typical Applications

• Automotive electronic modules: Energy storage and power conditioning in electronic control units and power distribution, leveraging AEC-Q200 qualification and 5,000 h endurance at 105°C.
• Power supply filtering: Bulk capacitance for smoothing and transient handling where high ripple current (9.474 A at 120 Hz / 2.97 A at 200 kHz) and low impedance are required.
• High-temperature environments: Systems operating up to 105°C that require sustained capacitance and controlled leakage over long life cycles.

Unique Advantages

• High energy density in a compact through-hole can: 10,000 µF in a φ18 × 40 mm package reduces board space compared with multiple smaller parts.
• Engineered for sustained thermal stress: 5,000-hour rating at 105°C supports long-term reliability in elevated-temperature applications.
• Designed for high ripple environments: Specified ripple-current ratings enable fewer parallel components and simpler thermal management in power designs.
• Automotive-grade qualification: AEC-Q200 qualification targets designs that require standardized reliability validation for automotive applications.
• Manufacturing-friendly packaging: Bulk and bag packing options accommodate a range of production and assembly workflows.
• Regulatory compliance: RoHS compliance simplifies selection for regulated product lines.
