UWR1A220MCL1GB

The UWR1A220MCL1GB is a 22 µF, 10 V polarized aluminum electrolytic capacitor in a compact surface-mount radial can package. It is designed for surface mounting on high-density PCBs and is supplied in embossed carrier tape for automated assembly.

This part is AEC-Q200 rated and RoHS compliant, offering controlled dissipation factor and defined ripple handling for demanding automotive and industrial electronics. Note: this product is discontinued and not recommended for new designs.

Key Features

• Capacitance & Tolerance — 22 µF nominal with ±20% tolerance at 120 Hz, 20°C for predictable bulk and decoupling performance.
• Rated Voltage — 10 V DC rating suitable for low-voltage rail applications.
• Dissipation Factor (tan δ) — 0.24 specified at 20°C and 120 Hz, providing a defined loss characteristic for design verification.
• Ripple Current Handling — 30 mA at 120 Hz (low frequency) and 45 mA at 10 kHz (high frequency) for decoupling and smoothing on active power rails.
• Leakage Current — Specified at 3 µA, enabling low-bleed applications and stable bias behavior.
• Reliability & Endurance — 2000 hours load life at 85°C, with endurance characteristics defined in the datasheet for long-term operation.
• Temperature Range — Rated for operation from −40°C to 85°C to cover a wide range of environmental conditions.
• Package & Mounting — φ4 × 5.4L (L: 5.4 × D: 4 mm) radial can SMD, surface-mountable and supplied in embossed carrier tape for pick-and-place assembly.
• Qualification & Compliance — AEC-Q200 rated and RoHS compliant for regulated environments and automotive-grade design requirements.

Typical Applications

• Automotive Electronics — Suitable for power filtering and decoupling in automotive control modules and subsystems where AEC-Q200 qualification is required.
• Power Supply Decoupling — Use on 10 V rails for smoothing and transient suppression in compact power stages and DC–DC converters.
• High-density Surface-mount Assemblies — Designed for mounting on high-density PCBs and automated assembly lines thanks to embossed carrier tape packaging.
• Sensor and Control Modules — Provides stable capacitance and low leakage across −40°C to 85°C for embedded sensor and control electronics.

Unique Advantages

• Automotive-ready qualification: AEC-Q200 rating supports usage in applications with defined automotive component requirements.
• Compact SMD radial can: φ4 × 5.4L size delivers useful capacitance in a small footprint for space-constrained board layouts.
• Defined electrical behavior: Specified tan δ, leakage, and ripple current values simplify verification and margining during design.
• Endurance under load: 2000 hours at 85°C provides a clear, tested life metric for reliability planning.
• Assembly-friendly packaging: Embossed carrier tape supports automated pick-and-place, reducing BOM handling complexity.

Why Choose UWR1A220MCL1GB?

The UWR1A220MCL1GB combines a compact SMD radial-can package with clearly defined electrical and endurance specifications—22 µF capacitance, 10 V rating, controlled dissipation factor, low leakage, and ripple-current values—making it straightforward to validate in production-grade designs. Its AEC-Q200 rating and −40°C to 85°C operating range align it with automotive and industrial applications that require qualified components.

Use this part when you need a small-profile electrolytic capacitor with documented ripple handling, leakage, and life test data for system-level reliability assessments. Keep in mind the product is discontinued and is best suited for maintenance, repair, or legacy-support scenarios rather than new designs.
