UPS2W220MHD

The Nichicon UPS2W220MHD is a miniature-sized, low-impedance aluminum electrolytic capacitor engineered for switching power supplies and general-purpose power applications. It is a radial-lead, polarized can-type capacitor offering a 22 µF capacitance at a 450 V rating with RoHS compliance.

Designed for compact designs, the UPS2W220MHD delivers specified ripple handling, a wide operating temperature range, and defined high-temperature endurance to support reliable operation in elevated-temperature environments.

Key Features

• Electrical rating — 22 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance, suitable for high-voltage DC applications where a compact electrolytic is required.
• Low impedance and ripple capability — Specified ripple current of 115 mA at 120 Hz and 184 mA at 10 kHz, supporting smoothing and ripple suppression in switching supply circuits.
• Thermal performance and endurance — Operating temperature range of −25°C to 105°C with a rated lifetime of 3000 hours at 105°C under specified conditions.
• Package and mounting — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions (L: 3.05 × D: 1.6 cm) for space-constrained PCB layouts.
• Polarized, general-purpose — Polarized construction tailored for power supply filtering and general-purpose DC smoothing tasks.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting common environmental directive requirements.

Typical Applications

• Switching power supplies — Filtering and smoothing on high-voltage DC rails where miniature, low-impedance capacitors are required.
• Space-constrained power modules — Miniature size and radial-lead format make it suitable for compact power assemblies and module-level filtering.
• General-purpose electronic equipment — General-purpose power filtering and decoupling in industrial and commercial electronics.

Unique Advantages

• High-voltage capability: 450 V rating supports higher DC bus and rail voltages without requiring larger components.
• Compact footprint: Small can-style package (L: 3.05 × D: 1.6 cm) and 7.5 mm lead spacing enable denser PCB layouts.
• Defined ripple performance: Explicit ripple current ratings at 120 Hz and 10 kHz allow straightforward thermal and performance trade-off calculations.
• Elevated-temperature endurance: 3000 hours at 105°C provides a quantified life expectation for designs operating at high ambient temperatures.
• Through-hole simplicity: Radial lead mounting simplifies prototyping and assembly for traditional PCB processes.
• Standards-aligned: RoHS compliance supports environmental regulatory requirements.
