UPS1E221MPD

The UPS1E221MPD is a miniature, low-impedance aluminum electrolytic capacitor from Nichicon's UPS series designed for switching power supplies and general-purpose power filtering. It is a radial-lead, polarized can-type capacitor that combines compact dimensions with focused ripple-handling and a wide operating temperature range.

Key attributes include a 220 µF capacitance at 25 V, an operating range of −55°C to 105°C, and specified endurance and ripple-current ratings that make it suitable for space-constrained power-electronics designs.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 25 V for energy storage and decoupling in power rails.
• Low Impedance — Specified impedance of 280 mOhm to improve smoothing and reduce voltage ripple in switching circuits.
• Ripple Current Capability — Rated for 205 mA at 120 Hz and 410 mA at 10 kHz to support AC ripple in power-conversion applications.
• Wide Temperature Range & Endurance — Operates from −55°C to 105°C with a rated lifetime of 2000 hours at 105°C.
• Radial Lead Package — Through-hole radial can with 3.5 mm lead spacing and compact dimensions (L: 1.15 × D: 0.8 cm) for straightforward PCB assembly in compact layouts.
• Polarized with Standard Tolerance — Polarized element with ±20% capacitance tolerance for predictable design margins.
• RoHS Compliant — Meets applicable RoHS requirements for environmental compliance.

Typical Applications

• Switching Power Supplies — Bulk and output smoothing where low impedance and compact size reduce ripple and board area.
• DC–DC Converters — Input/output decoupling to stabilize intermediate rails and support transient currents.
• Embedded Power Modules — Space-constrained power subsystems that require reliable filtering across a wide temperature range.
• General-Purpose Electronics — Power-rail decoupling and energy storage in consumer and industrial electronic assemblies.

Unique Advantages

• Compact, space-saving footprint — Small case dimensions (L: 1.15 × D: 0.8 cm) and radial leads help minimize PCB area in tight layouts.
• Improved ripple suppression — Low impedance (280 mOhm) combined with specified ripple-current ratings reduces AC excursion on power rails.
• Wide temperature endurance — Rated for −55°C to 105°C operation and 2000 hours at 105°C, supporting long-term use in elevated-temperature environments.
• Through-hole reliability — Radial-lead, can-style package simplifies mechanical retention and soldering for robust connections.
• Regulatory readiness — RoHS compliance assists designs targeting regulated markets.
