UCD2A221MNS1MS

The UCD2A221MNS1MS is a chip‑type, low‑impedance aluminum electrolytic capacitor engineered for surface mounting on high‑density printed circuit boards. Built for applications requiring elevated temperature tolerance and robust performance, it combines a 220 µF capacitance with a 100 V rated voltage in a compact SMD can package.

Designed for automated assembly, RoHS compliance and AEC‑Q200 qualification make this part suitable for demanding industrial and automotive electronics where long‑term reliability and thermal endurance are required.

Key Features

• Type & Construction — Chip‑type aluminum electrolytic capacitor in a radial can SMD package designed for surface mounting on high‑density PCBs and compatible with carrier‑tape automated placement.
• Electrical Rating — 220 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• Low Impedance Performance — Low‑impedance design for improved ripple handling; specified ripple current of 458.5 mA at 120 Hz and 917 mA at 10 kHz.
• Temperature Range — Rated for operation from −55 °C to +105 °C to support elevated‑temperature environments.
• Reliability & Lifetime — AEC‑Q200 qualified with a rated lifetime of 5000 hours at 105 °C (per product specifications) and defined endurance characteristics after high‑temperature voltage application.
• Leakage & Loss Characteristics — Leakage current limited to 0.01 CV or 3 µA (whichever is greater) after 2 minutes at 20 °C; tan δ limits specified up to 100 V (e.g., 0.07 max at 100 V, measurement at 120 Hz, 20 °C).
• Mechanical & Land Pattern — Size L: 1.65 cm × D: 1.8 cm with recommended surface‑mount land size 1.83 cm × 1.83 cm for PCB footprint planning.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering and decoupling — Provides bulk capacitance and low impedance at higher frequencies for DC bus smoothing and transient suppression in power converter and regulator circuits.
• Automotive electronics — AEC‑Q200 qualification and extended temperature range make it suitable for in‑vehicle control modules and power management where thermal endurance is required.
• Industrial control systems — Long lifetime at elevated temperature and high ripple capability support motor drives, PLCs, and factory automation power electronics.
• High‑density PCB assemblies — Chip form factor and carrier‑tape compatibility enable automated placement in compact boards and space‑constrained designs.

Unique Advantages

• High temperature endurance: Rated for operation up to +105 °C with a specified 5000‑hour lifetime at that temperature, enabling reliable service in thermally demanding environments.
• Automated assembly ready: Carrier‑tape compatibility and SMD can package simplify high‑volume production and reduce assembly time and handling costs.
• Designed for ripple performance: Defined ripple current specifications at both low and high frequencies (120 Hz and 10 kHz) support stable operation in switching and linear power stages.
• Qualification for automotive use: AEC‑Q200 qualification provides added confidence for designs targeting automotive electronics and other high‑reliability markets.
• Regulatory compliance: RoHS conformity supports use in regions and programs requiring restricted‑substance compliance.
