UPW1V221MPD

The UPW1V221MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UPW series designed for low-impedance, high-reliability applications. It delivers 220 µF at 35 V in a compact φ10 × 12.5 mm can and is optimized for switching power supplies and automotive electronic systems.

With an extended operating range from −55°C to 105°C, AEC-Q200 rating, and a 5000-hour endurance at 105°C, this part addresses demanding thermal and lifetime requirements while maintaining low impedance and controlled loss characteristics.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance with a 35 V nominal voltage and tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 180 mΩ, supporting stable decoupling and smoothing in power circuits.
• Loss Characteristics — tanδ (DF) of 0.12 measured at 20°C and 120 Hz, providing predictable ESR-related behavior.
• Ripple and Leakage — Low-frequency ripple current 494 mA (120 Hz), high-frequency ripple current 760 mA (10 kHz), and leakage current specified at 231 µA.
• High Reliability & Qualification — AEC-Q200 rated with endurance of 5000 hours at 105°C under rated conditions.
• Wide Temperature Range — Operates from −55°C to 105°C for use in thermally challenging environments.
• Compact Radial Form Factor — Radial lead, can-style package with φ10 × 12.5 mm dimensions and 5 mm lead spacing for through-hole designs; available in bulk or bag packing.

Typical Applications

• Switching Power Supplies — Local bulk decoupling and output smoothing where low impedance and compact size are required.
• Automotive Electronic Systems — Designed for automotive use, suitable for electronic control modules and power management subsystems that require AEC-Q200-qualified components.
• DC–DC Converters — Input/output filtering and transient absorption in small footprint power modules.

Unique Advantages

• Miniature footprint with high capacitance — 220 µF in a φ10 × 12.5 mm can minimizes board area while preserving bulk capacitance.
• Measured low impedance — 180 mΩ impedance helps improve voltage stability and reduce ripple at the load.
• Robust ripple handling — Specified ripple currents at both low and high frequencies support real-world switching environments.
• Automotive-grade reliability — AEC-Q200 rating and 5000 hours endurance at 105°C provide qualification for demanding lifetimes and thermal stress.
• Wide operating temperature — −55°C to 105°C rating enables use across harsh temperature ranges common in industrial and automotive applications.
