UCZ1J221MNQ1MS

The UCZ1J221MNQ1MS from Nichicon is a chip‑type aluminum electrolytic capacitor designed for surface‑mount assembly and high‑temperature operation. It combines a 220 µF capacitance at 63 V with an extended operating range of −40 °C to +125 °C and AEC‑Q200 qualification for demanding applications.

Engineered for reliability under thermal stress, this SMD radial can is carrier‑tape compatible for automatic mounting and provides defined ESR behavior after low‑temperature testing, making it suitable for power‑filtering and decoupling in harsh environments.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with a 63 V rated voltage and ±20% tolerance for bulk energy storage and decoupling.
• High Temperature Endurance: Operates from −40 °C to +125 °C with a specified lifetime of 3000 hours at 125 °C, supporting sustained performance in hot environments.
• Low‑temperature ESR Specification: ESR characterized after −40 °C testing; specified equivalent series resistance is 200 mΩ at 100 kHz for predictable high‑frequency behavior.
• Ripple Handling: Rated ripple current of 500 mA at 120 Hz and 1 A at 100 kHz to support both low‑ and high‑frequency power applications.
• Surface‑mount Radial Can Package: Chip‑type (radial, can) SMD package with surface mount land size 12.8 mm × 12.8 mm; compatible with carrier tape for automated placement.
• Qualifications & Compliance: AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), meeting industry requirements for reliability and environmental regulation.

Typical Applications

• Automotive Power Rails: Stabilizes and decouples power supplies and control modules where AEC‑Q200 qualification and 125 °C performance are required.
• Industrial Power Electronics: Bulk filtering and energy storage in high‑temperature motor drives, converters, and power control units.
• Embedded and Control Systems: Decoupling and smoothing for regulators and downstream power stages in harsh thermal environments.
• High‑frequency Power Circuits: Enables predictable ripple and ESR behavior for circuits operating with both low‑ and high‑frequency components.

Unique Advantages

• Predictable ESR after Low‑Temperature Stress: ESR specified following −40 °C testing ensures designers know post‑test impedance characteristics for robust system margins.
• Long High‑Temperature Lifetime: 3000 hours at 125 °C provides a measurable endurance baseline for thermal reliability planning.
• Dual‑Frequency Ripple Capability: Rated ripple current at 120 Hz and 100 kHz supports a range of power conversion and filtering topologies.
• Automated Assembly Ready: Carrier‑tape compatible SMD can package simplifies high‑volume placement and reduces manufacturing complexity.
• Industry Qualification and Compliance: AEC‑Q200 qualification plus RoHS compliance align the component with regulated and safety‑conscious supply chains.
