UCZ2A221MNS1MS

The UCZ2A221MNS1MS is a high‑reliability aluminum electrolytic chip capacitor designed for operation up to +125°C. It combines a 220 µF capacitance with a 100 V rated voltage and polarized chip packaging suitable for automated surface‑mount assembly.

Engineered for demanding environments, this AEC‑Q200 qualified, RoHS‑compliant part delivers low temperature ESR behavior, defined ripple current capability, and long life at elevated temperature for applications that require stable power filtering and energy storage under thermal stress.

Key Features

• Capacitance & Voltage — 220 µF capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High temperature range — Specified for operation from −40 °C to +125 °C to support elevated ambient and under‑hood environments.
• Low‑temperature ESR spec — ESR specification includes performance after a −40 °C test; nominal ESR is 120 mΩ measured at 100 kHz.
• Ripple current capability — Rated ripple current of 800 mA at 120 Hz and 1.6 A at 10 kHz for handling AC stress in filtering applications.
• Long high‑temperature lifetime — Rated lifetime of 4000 hours at 125 °C, providing extended endurance under continuous elevated temperature operation.
• Surface‑mount chip packaging — Radial can, SMD chip type designed for automatic mounting with carrier tape; surface mount land size provided (L: 1.63 × W: 1.63 cm).
• Reliability & compliance — AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and automotive designs.
• Polarized aluminum electrolytic — Polarized configuration with leakage current specification of not more than 0.01CV (μA) after 2 minutes at 20 °C, per series datasheet.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and −40 °C to +125 °C rating make this capacitor suitable for automotive modules that require reliable bulk capacitance and filtering under wide temperature extremes.
• High‑temperature power conversion — 100 V rating, 220 µF capacitance and defined ripple currents (800 mA @120 Hz; 1.6 A @10 kHz) support DC link and smoothing functions in power converters operating at elevated temperatures.
• Harsh‑environment surface‑mount assemblies — Chip form factor manufactured for carrier‑tape feeding and proven resistance to soldering heat enable automated PCB assembly for compact, rugged designs.

Unique Advantages

• Designed for elevated ambient use — Specified operation to +125 °C and a 4000‑hour life rating at that temperature reduce risk in applications exposed to sustained heat.
• Verified low‑temperature ESR — Added ESR specification after −40 °C testing ensures predictable impedance behavior across the operating temperature range.
• Measured ripple handling — Published ripple current ratings at both low and high frequencies provide clear limits for thermal and AC stress budgeting in designs.
• AEC‑Q200 qualification — Qualification supports use in safety‑critical and reliability‑sensitive systems where automotive‑grade components are required.
• Surface‑mount compatibility — Chip SMD construction and carrier‑tape feed compatibility streamline high‑volume automated assembly.
• Regulatory compliance — RoHS compliance simplifies integration into products that must meet environmental directives.
