UPS1A221MED

The UPS1A221MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPS series. It is a radial-lead, polarized capacitor with a 220 µF capacitance and a 10 V rated voltage, designed for low-impedance performance in compact power applications.

Key electrical and mechanical attributes include a wide operating temperature range of −55°C to 105°C, a rated lifetime of 2000 hours at 105°C, and RoHS compliance. The part is supplied in bulk or bag packing and is suited for general-purpose use and switching power supply applications where space and ripple handling matter.

Key Features

• Capacitance & Voltage — 220 µF at a 10 V rating with capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low-loss characteristics — tan δ = 0.20 specified at 20°C, 120 Hz to characterize dissipation for stable performance under AC conditions.
• Ripple current capability — Low-frequency ripple current of 125 mA at 120 Hz and high-frequency ripple current of 250 mA at 10 kHz, enabling effective smoothing in switching applications.
• Leakage current — Specified leakage current of 66 µA (measured after 1 minute at 20°C), providing predictable bias behavior in circuits.
• High-temperature endurance — Rated for 2000 hours at 105°C, supporting designs requiring prolonged operation at elevated temperatures.
• Miniature radial package — Compact can size φ6.3 × 11 mm with 2.5 mm lead spacing (±0.5 mm), ideal for space-constrained board layouts; radial lead mounting for through-hole assembly.
• Polarized, general-purpose — Polarized aluminum electrolytic construction for general-purpose power filtering and decoupling.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
• Packaging options — Available in bulk (no terminal forming) or bag packing to support various assembly workflows.

Typical Applications

• Switching power supplies — Low impedance and specified ripple current values make this capacitor suitable for output filtering and smoothing in compact switching regulators.
• General-purpose power filtering — Polarized 220 µF capacitance supports decoupling and bulk energy storage in small power subsystems.
• Space-constrained designs — Miniature φ6.3 × 11 mm radial package fits compact PCBs where board area is limited.

Unique Advantages

• Compact footprint: φ6.3 × 11 mm can size and 2.5 mm lead spacing reduce board area while keeping through-hole mounting simplicity.
• Predictable ripple handling: Published ripple current ratings for both low and high frequency (125 mA at 120 Hz, 250 mA at 10 kHz) allow designers to size the capacitor to actual power-supply conditions.
• Defined high-temperature life: 2000 hours at 105°C gives a clear reliability expectation for elevated-temperature applications.
• Measured electrical loss and leakage: Specified tan δ and leakage current values (0.20 and 66 µA respectively) enable accurate circuit simulation and margining.
• RoHS compliance: Helps meet regulatory requirements for restricted substances in finished products.
• Packaging flexibility: Bulk or bag packing options support different assembly and handling processes.
