UPS2F220MHD

The UPS2F220MHD is a miniature, low-impedance aluminum electrolytic capacitor from Nichicon’s UPS series designed for power electronics. It is a polarized, radial-lead radial-can capacitor rated at 22 µF and 315 V, engineered for general-purpose use and switching power supply applications.

Key value propositions include a compact footprint, defined ripple-current performance for AC-biased DC rails, wide operating temperature range, and a long endurance rating at elevated temperature. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance rated at 315 V for high-voltage DC filtering and energy storage.
• Miniature radial-can package — compact physical size (L: 2.5 × D: 1.25 cm) with radial leads and 5 mm lead spacing for through-hole mounting.
• Low impedance / Ripple handling — specified ripple current of 120 mA at 120 Hz and 192 mA at 10 kHz to support ripple-laden DC rails.
• Wide operating range — specified to operate from −40 °C to +105 °C to tolerate typical industrial and commercial temperature environments.
• Endurance at high temperature — rated for 3000 hours at 105 °C, supporting long-term stability under elevated thermal stress.
• Polarized, general-purpose — designed as a polarized aluminum electrolytic for DC power applications.
• RoHS compliant — meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.

Typical Applications

• Switching Power Supplies — bulk filtering, smoothing and decoupling on high-voltage DC rails in switch-mode power designs.
• General Power Filtering — energy storage and ripple suppression in discrete power stages and power distribution circuits.
• Industrial Power Electronics — board-level DC conditioning where compact size and defined ripple capability are required.

Unique Advantages

• Compact high-voltage capability: 315 V rating in a small radial-can footprint enables space-efficient designs on high-voltage rails.
• Engineered for ripple duty: Published ripple-current figures at both low and high frequencies help designers size capacitors for expected AC bias and ripple loading.
• Thermal endurance: 3000 hours at 105 °C provides a measurable baseline for long-term performance in warm operating environments.
• Through-hole simplicity: Radial lead and 5 mm lead spacing simplify placement and replacement in through-hole assemblies.
• Regulatory alignment: RoHS compliance supports environmental and regulatory requirements for commercial and industrial products.
