UBT1C221MPD

The UBT1C221MPD is a radial-lead aluminum electrolytic capacitor offering 220 µF capacitance at a 16 V rating in a compact φ10 × 12.5 mm can. It is built for high-temperature operation up to 125°C with a rated endurance of 5000 hours at 125°C, making it suitable for demanding electronics where long-term thermal stability and sustained ripple handling are required.

Designed as part of the UBT series from Nichicon, this polarized capacitor delivers measurable low leakage and defined ripple current performance for power-conditioning roles in rugged systems, and carries AEC-Q200 qualification and RoHS compliance as listed in the product specifications.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with ±20% tolerance and a 16 V rated voltage, suitable for bulk decoupling and energy storage in low-voltage power rails.
• High‑Temperature Endurance: Rated for operation from −40°C to +125°C with a specified life of 5000 hours at 125°C, supporting sustained performance in elevated ambient conditions.
• Ripple Current Performance: Low-frequency ripple current 415.4 mA (120 Hz) and high-frequency ripple current 620 mA (100 kHz), enabling effective smoothing under both AC and switching environments.
• Low Leakage: Leakage current specified at 105.6 µA, providing predictable standby loss for power-sensitive designs.
• Package & Mounting: Radial-lead, can-style package with φ10 × 12.5 mm body size and 5 mm lead spacing (±0.5 mm), for through-hole mounting and straightforward PCB placement.
• Automotive & Reliability Ratings: AEC-Q200 qualified and RoHS compliant, aligning with qualification needs for vehicle electronics and regulated environments.

Typical Applications

• Automotive Electronics: Power conditioning and smoothing in vehicle systems where AEC-Q200 qualification and high-temperature endurance are required.
• Power Supply Filtering: Bulk decoupling and ripple suppression on low-voltage rails, leveraging specified ripple current capability for switching and linear regulators.
• Industrial Control: Energy storage and transient buffering in control modules subject to elevated operating temperatures and continuous duty cycles.

Unique Advantages

• High-temperature durability: 5000 hours of rated life at +125°C gives designers a defined reliability envelope for thermal-stressed applications.
• Automotive-grade qualification: AEC-Q200 listing supports use in vehicle electronic assemblies that require component-level qualification.
• Measurable ripple and leakage specs: Specified ripple currents (120 Hz and 100 kHz) and a low leakage current provide clear design margins for power-conditioning tasks.
• Compact, through-hole form factor: φ10 × 12.5 mm can with 5 mm lead spacing offers a small footprint for radial, through-hole layouts while retaining useful capacitance.
• Regulatory compliance: RoHS-compliant construction supports deployments in regulated supply chains.
