UVK1E221MED

The UVK1E221MED is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UVK series, offering 220 µF capacitance at a 25 V rated voltage in a compact φ6.3 × 11 mm can. Designed for general-purpose electronic applications, it delivers bulk capacitance and measured performance data suitable for space-constrained assemblies.

Key Features

• Capacitance and Voltage: 220 µF rated capacitance with a 25 V rated voltage and capacitance tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Miniature Radial Package: Small form factor (φ6.3 × 11 mm) with radial lead mounting and 2.5 mm lead spacing for compact PCB layouts.
• Loss Characteristics: Tangent of loss angle (tan δ) specified at 0.16 (measured at 120 Hz, 20°C), enabling predictable AC behavior for design verification.
• Ripple Current Capability: Low-frequency ripple current of 280 mA (120 Hz) and high-frequency ripple current of 420 mA (10 kHz), allowing selection based on operating ripple conditions.
• Leakage Current: Specified leakage current of 165 µA, enabling conservative margining for bias and hold-up calculations.
• Temperature and Endurance: Rated for operation from -40°C to +85°C with an endurance specification of 2000 hours at 85°C under rated voltage.
• RoHS Compliant: Conforms to RoHS requirements as noted for the UVK series.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to suit assembly or prototyping workflows.

Typical Applications

• General-purpose electronic circuits: Provides 220 µF bulk capacitance in compact PCBs where radial-lead mounting is preferred.
• Compact power modules: Small φ6.3 × 11 mm package and 2.5 mm lead spacing help conserve board area while supplying energy storage at 25 V.
• Temperature-challenged assemblies: Operates across -40°C to +85°C with a 2000-hour endurance rating at 85°C for designs requiring verified thermal performance.

Unique Advantages

• Space-efficient footprint: Miniature φ6.3 × 11 mm can reduces PCB area compared with larger radial electrolytics, useful for dense layouts.
• Measured AC performance: Specified tan δ (0.16 at 120 Hz) and documented ripple current values (280 mA @120 Hz, 420 mA @10 kHz) allow accurate thermal and ripple-loss calculations.
• Predictable leakage behavior: Leakage current specified at 165 µA supports reliable bias planning and low-current system considerations.
• Broad temperature tolerance: -40°C to +85°C operating range enables use across a wide set of ambient conditions common to general-purpose electronics.
• Industry-standard radial lead form: 2.5 mm lead spacing and standard radial can packaging simplify replacement and prototyping on through-hole boards.
