UPS1V221MPD

The UPS1V221MPD from Nichicon is a miniature, low-impedance aluminum electrolytic capacitor in the UPS series designed for switching power supplies and general-purpose electronic circuits. It is a polarized, radial-lead can-style capacitor specified at 220 µF and 35 V, offering compact dimensions and performance-oriented electrical characteristics for space-constrained power designs.

Key value propositions include a wide operating temperature range (−55 °C to 105 °C), measurable ripple-current capability, and RoHS compliance (2011/65/EU, (EU)2015/863), making it suitable for compact power modules and designs requiring robust electrolytic smoothing or decoupling components.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance at a rated voltage of 35 V with a tolerance of ±20% (120 Hz, 20 °C).
• Low Impedance: Specified impedance of 190 mΩ, supporting low-impedance filtering and decoupling in switching power applications.
• Ripple Current Capability: Rated ripple current of 300 mA at 120 Hz and 600 mA at 10 kHz, enabling effective AC ripple handling across common switching frequencies.
• Wide Temperature Range & Endurance: Operating temperature from −55 °C to 105 °C with a stated lifetime of 2000 hours at 105 °C.
• Package & Mounting: Radial lead, can-style package with 5 mm lead spacing; compact size L: 1.25 × D: 1.0 cm and maximum seated height 1.25 cm for space-efficient through-hole assembly.
• Polarized, General Purpose: Polarized electrolytic construction suitable for general-purpose smoothing, decoupling, and energy-storage roles in power circuits.
• Environmental Compliance: RoHS compliant to 2011/65/EU and (EU)2015/863 requirements.

Typical Applications

• Switching Power Supplies: Bulk smoothing and decoupling where a compact, low-impedance electrolytic is required for stable DC output.
• Compact Power Modules and DC–DC Converters: Fits tight through-hole layouts while delivering ripple-current handling across common switching frequencies.
• Industrial Control and Instrumentation: Wide operating temperature range (−55 °C to 105 °C) supports use in temperature-challenging environments.
• Consumer and Embedded Electronics: General-purpose energy storage and decoupling in space-constrained circuit assemblies that require RoHS-compliant components.

Unique Advantages

• Low-Z performance: 190 mΩ impedance provides measurable reduction in AC voltage drop for filtering tasks, directly improving ripple attenuation when combined with the capacitor’s ripple-current ratings.
• Compact footprint: Small can dimensions (L: 1.25 × D: 1.0 cm) and 5 mm lead spacing save board space in through-hole designs while maintaining expected electrolytic capacitance.
• Frequency-flexible ripple handling: Defined ripple-current values at 120 Hz and 10 kHz allow designers to evaluate performance across both low- and high-frequency ripple conditions.
• Wide temperature endurance: −55 °C to 105 °C operating range and 2000 hours at 105 °C rated lifetime support reliable operation under elevated temperatures.
• Through-hole assembly friendly: Radial lead can package simplifies PCB placement and manual or wave solder assembly processes.
• Regulatory compliance: RoHS conformity helps meet environmental requirements for commercial and industrial products.
