UVR1C222MHD

The UVR1C222MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UVR series, offering 2200 µF capacitance at a 16 V rating. It combines a compact miniature can (φ12.5 × 20 mm) with performance characteristics suited for general-purpose and entertainment electronics applications.

Designed for power-filtering and decoupling in space-constrained assemblies, this component delivers measurable ripple-handling capability and long-term endurance for sustained operation up to 85°C.

Key Features

• Capacitance and Voltage: 2.2 mF (2200 µF) rated at 16 V with a capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20°C).
• Electrical Loss (tan δ): Dissipation factor (tan δ) of 0.22 measured at 20°C, 120 Hz, providing a defined loss characteristic for circuit design.
• Ripple Current Capability: Low-frequency ripple current 1.3 A (120 Hz) and high-frequency ripple current 1.495 A (10 kHz) to support smoothing and decoupling tasks across common supply frequencies.
• Leakage Current: Specified leakage current of 1056 µA for predictable standby and bias behavior in circuits.
• Reliability & Endurance: Rated endurance of 2000 hours at 85°C with specified post-test limits for capacitance, tan δ and leakage current.
• Mechanical & Mounting: Radial lead, can-style package with diameter 12.5 mm, length 20 mm, and 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Temperature Range & Compliance: Operating temperature −40°C to +85°C and RoHS-compliant construction.

Typical Applications

• Entertainment Electronics: Filtering and decoupling in audio/video and consumer entertainment equipment where compact, reliable bulk capacitance is required.
• General-Purpose Power Filtering: Smoothing and ripple attenuation on low-voltage DC rails in a wide range of electronic products.
• Compact PCB Designs: Bulk energy storage and decoupling in space-constrained boards, enabled by the capacitor’s miniature φ12.5 × 20 mm can and radial-lead format.

Unique Advantages

• High Bulk Capacitance in Small Footprint: 2200 µF in a φ12.5 × 20 mm can provides substantial capacitance where board space is limited.
• Dual-Frequency Ripple Performance: Rated ripple currents at both 120 Hz (1.3 A) and 10 kHz (1.495 A) support filtering across low and higher frequency noise components.
• Defined Endurance Rating: 2000 hours at 85°C gives designers a clear reliability target for thermal-stressed applications.
• Predictable Loss and Leakage: Specified tan δ (0.22) and leakage current (1056 µA) allow accurate margining in power and bias designs.
• Radial-Lead Convenience: Through-hole radial leads and standard 5 mm lead spacing simplify prototyping and assembly for hand-solder or wave-solder processes.
• RoHS Compliant: Meets RoHS requirements for environmental and regulatory conformity.
