UPW1A221MED6

The UPW1A221MED6 is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series, designed for miniature, low-impedance, high-reliability power applications. This 220 µF, 10 V polarized capacitor offers a compact φ6.3 × 15 mm can and is targeted at switching power supplies and other compact power modules.

Key performance points include a wide operating temperature range (−55°C to 105°C), measurable low-loss behavior at 120 Hz, and rated ripple current capacity across low and high frequencies, making it suitable where compact size and reliable power filtering are required.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance at a 10 V rated voltage, with capacitance tolerance of -20% to 20%.
• Low dissipation (tan δ): tanδ = 0.19 measured at 20°C, 120 Hz and 10 V, indicating low energy loss in typical control frequencies.
• Ripple current capability: Low-frequency ripple current 279.5 mA (120 Hz) and high-frequency ripple current 430 mA (10 kHz), useful for both line-frequency and switching-frequency environments.
• Leakage current: Specified leakage current of 66 µA after application of rated voltage.
• Reliability and endurance: Rated life/endurance of 2000 hours at 105°C, supporting sustained high-temperature operation.
• Package & mounting: Radial lead, can-style package with dimensions φ6.3 × 15 mm and lead spacing 2.5 mm (±0.5 mm tolerance); available in bulk (no terminal forming) and bag packing.
• Operating temperature range: −55°C to 105°C, matching common industrial and demanding power environments.
• AEC qualification: AEC-Q200 rated, supporting use in automotive-class system designs.

Typical Applications

• Switching power supplies: Low-impedance, miniature capacitor for output smoothing and decoupling in compact switch-mode power supplies.
• Automotive electronics: AEC-Q200-rated capacitor for automotive electronic modules that require compact filtering components within a −55°C to 105°C temperature envelope.
• Compact DC–DC converters and power modules: Small footprint radial package suited to space-constrained converter assemblies where ripple handling and long life at elevated temperature are required.

Unique Advantages

• Miniature, low-impedance design: UPW series characterization as miniature and low impedance supports tighter decoupling in small form-factor power designs.
• Measured low-loss performance: tanδ = 0.19 at 20°C, 120 Hz (10 V measurement condition) for predictable dissipation in typical control-frequency circuits.
• Dual-frequency ripple capability: Specified ripple current values for 120 Hz and 10 kHz enable use across line-frequency and switching-frequency applications.
• High-temperature endurance: 2000 hours at 105°C endurance rating for sustained performance in elevated-temperature assemblies.
• Automotive-grade qualification: AEC-Q200 rating supports deployment in automotive electronic subsystems where industry qualification is required.
• Compact radial can package: φ6.3 × 15 mm can with 2.5 mm lead spacing allows straightforward through-hole mounting in dense layouts.
