UPW1C221MPD

The UPW1C221MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPW series, engineered for miniature, low-impedance energy storage in power electronics. It combines a 220 µF capacitance with a 16 V rating and is supplied in a compact radial can package suited to space-constrained designs.

Designed for reliable operation across a wide temperature range and continuous ripple duty, this part targets switching power supplies and other power-management circuits where low impedance, long life at elevated temperature, and regulated ripple handling are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 16 V rated voltage, tolerance ±20% (120 Hz, 20°C).
• Low Impedance — Specified impedance of 234 mΩ, minimizing AC voltage drop and improving transient response in power rails.
• Compact Radial Can — Small package dimensions L: 1.15 × D: 0.8 cm with radial lead mounting and 3.5 mm lead spacing for tight PCB layouts.
• High-Temperature Endurance — Rated operating temperature range −55°C to +105°C with a specified life of 3000 hours at 105°C.
• Ripple Current Capability — Handles 360.8 mA at 120 Hz and 555 mA at 10 kHz, supporting both low- and high-frequency ripple conditions.
• Polarized, Radial Lead — Standard polarized electrolytic construction in a radial-lead can for through-hole assembly.
• AEC-Q200 Qualified — Designed with AEC-Q200 reliability screening appropriate for demanding electronic applications.

Typical Applications

• Switching Power Supplies — Local bulk and decoupling capacitance for improving regulator stability and transient response in switch-mode power supplies.
• Automotive Electronics — Suitable for automotive-related power modules and control units where AEC-Q200 qualification and wide temperature range are required.
• DC–DC Converters — Input/output filtering and energy buffering in compact DC–DC converter modules that demand low impedance and measurable ripple handling.
• Power Management Modules — Bulk storage and smoothing in power-management circuits for industrial and embedded systems operating over broad temperatures.

Unique Advantages

• Space-efficient energy storage: 220 µF capacitance in a 1.15 × 0.8 cm can delivers significant capacitance in a compact footprint for densely packed boards.
• Lower AC loss: The 234 mΩ impedance rating reduces AC voltage drop and supports cleaner power rails under dynamic load conditions.
• Frequency-flexible ripple handling: Specified ripple current at both 120 Hz (360.8 mA) and 10 kHz (555 mA) supports filtering across low and high-frequency domains.
• Extended thermal endurance: Rated −55°C to +105°C with 3000 hours at 105°C, enabling continuous operation in elevated-temperature environments.
• Automotive-grade reliability: AEC-Q200 rating provides defined reliability screening for use in demanding applications.
