UWX1C220MCL1GB

The UWX1C220MCL1GB is a surface-mount aluminum electrolytic chip capacitor in Nichicon's UWX series, offering 22 µF capacitance at a 16 V rating in a compact chip package. It is designed for surface mounting on high-density PC boards and is compatible with automatic mounting equipment fed from carrier tape.

Key value comes from its automotive-grade AEC-Q200 rating, RoHS compliance, low leakage current, and a proven load life of 2000 hours at 85°C—suiting robust electronic designs that require compact, reliable bulk or decoupling capacitance.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance, providing stable bulk capacitance for mid-voltage rails.
• Compact Surface-Mount Package — Chip-type can SMD package sized 5.4 mm × 5.0 mm with a recommended land pattern of 5.3 mm × 5.3 mm for high-density PCB layouts.
• Reliability & Lifetime — Load life of 2000 hours at 85°C and operating temperature range of –40°C to +85°C, meeting endurance expectations for demanding environments.
• Automotive Qualification — AEC-Q200 compliant, suitable for use in automotive electronic designs requiring component-level qualification.
• Low Leakage & Ripple Capability — Specified leakage current of approximately 3.52 µA and ripple current ratings of 37 mA at 120 Hz and 55.5 mA at 10 kHz, supporting stable performance under AC loading.
• Environmental Compliance — RoHS compliant, aligned with current lead-free and hazardous-substance requirements.
• Polarized Design — Polar capacitor suitable for typical polarized applications on DC power rails.
• Assembly-Friendly — Designed for automatic placement from carrier tape to support volume production.

Typical Applications

• Automotive Electronics — Suited for automotive modules and onboard electronics that require AEC-Q200 qualification and stable operation across –40°C to +85°C.
• High-Density Surface-Mount Boards — Intended for compact PCBs where space-efficient chip-type capacitors and automatic placement are required.
• Power Rail Decoupling — Effective as bulk or decoupling capacitance on 12–16 V class power rails where 22 µF at 16 V is appropriate.

Unique Advantages

• AEC-Q200 Compliant: Provides component-level qualification for automotive-grade designs, reducing redesign risk in qualified systems.
• Proven Endurance: 2000-hour life at 85°C supports long-term stability in elevated-temperature environments.
• Low Leakage Current: Low specified leakage (~3.52 µA) helps minimize standby losses and maintain circuit stability.
• Compact Footprint: Small chip package and recommended land pattern enable efficient use of PCB real estate on high-density boards.
• Ripple Handling: Defined ripple current ratings at 120 Hz and 10 kHz allow designers to assess AC stress performance for power applications.
• RoHS Compliant: Meets current environmental directives for restricted substances.
