UBT1C221MPD8

The UBT1C221MPD8 is a Nichicon UBT-series aluminum electrolytic capacitor in a radial-lead can, offering 220 µF capacitance at a 16 V rating. Designed for demanding thermal environments, it provides high-temperature endurance and electrical performance for applications requiring reliable power smoothing and bulk energy storage.

Key value propositions include high ripple-current capability, low impedance, AEC-Q200 qualification, and a wide operating temperature range, making it suitable for automotive and other heavy-duty electronics where long-term stability at elevated temperatures is required.

Key Features

• Capacitance and Voltage — 220 µF at 16 V rated voltage with ±20% tolerance for predictable bulk energy storage and decoupling performance.
• High-temperature endurance — Rated for operation from −40 °C to 125 °C with a specified lifetime of 5000 hours at 125 °C for the φ10 package size.
• Ripple current capability — Low-frequency ripple current 415.4 mA (120 Hz) and high-frequency ripple current 620 mA (100 kHz) to support power-rail filtering under dynamic loads.
• Low impedance and loss — Impedance of 150 mΩ and tan δ of 0.16 (at 120 Hz, 20 °C) for efficient filtering and reduced heat generation.
• Compact radial can package — φ10 × 12.5 mm body (size L: 12.5 mm × D: 10 mm) with 5 mm lead spacing, radial-lead mounting for through-hole designs.
• Leakage current — Specified leakage current of 105.6 µA, supporting predictable standby and bias characteristics.
• Automotive-grade qualification — AEC-Q200 rating and RoHS compliance, reflecting suitability for automotive electronics and regulatory environmental requirements.
• Packaging and production — Supplied in bulk (no terminal forming) or bag packing; indicated as mass production availability.

Typical Applications

• Automotive electronics — Power supply smoothing and decoupling in control modules and electronic units that require high-temperature endurance and AEC-Q200 qualification.
• Power rail filtering — Local bulk capacitance and ripple suppression on DC-DC converters and voltage regulators where reliable ripple handling is needed.
• Embedded and industrial systems — Energy storage and decoupling for systems operating across −40 °C to 125 °C ambient ranges.

Unique Advantages

• Proven high-temperature life: 5000 hours endurance at 125 °C for the φ10 package delivers predictable long-term performance in hot environments.
• Automotive-grade qualification: AEC-Q200 rating supports use in automotive electronics designs that demand component-level reliability.
• High ripple handling: Dual ripple-current specifications (120 Hz and 100 kHz) enable designers to evaluate performance across low- and high-frequency stress conditions.
• Compact footprint with radial leads: φ10 × 12.5 mm can with 5 mm lead spacing provides a small, serviceable through-hole option for power electronics layouts.
• Low impedance and controlled dissipation: 150 mΩ impedance and 0.16 tan δ contribute to efficient filtering with reduced self-heating.
• Regulatory and environmental compliance: RoHS-compliant construction supports regulatory requirements for lead-free electronic assemblies.
