UPS2E220MHD

The UPS2E220MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPS series, designed for low-impedance, high-reliability power applications. It is a polarized, radial-lead component rated at 22 µF and 250 V, optimized for use in switching power supplies and general-purpose power filtering where compact size and stable performance are required.

Key value comes from its compact φ12.5 × 25 mm can, wide operating range (−40°C to 105°C), and endurance rating of 3000 hours at 105°C, providing designers measurable lifetime and thermal performance for demanding PCB power circuits.

Key Features

• Electrical Characteristics — 22 µF nominal capacitance with ±20% tolerance, rated for 250 V DC. Specified tangent of loss angle (tanδ) is 0.15 measured at 20°C, 120 Hz.
• Ripple Performance — Low-frequency ripple current of 155 mA at 120 Hz and high-frequency ripple current of 248 mA at 10 kHz, enabling effective AC ripple handling in power supply circuits.
• Leakage and Loss — Leakage current specified at 320 µA (per part data) and low dissipation factor to help minimize power loss in filtering and smoothing applications.
• Thermal and Endurance — Rated operating temperature from −40°C to 105°C with endurance of 3000 hours at 105°C under rated conditions, providing quantified long-term performance for elevated-temperature environments.
• Compact Radial Package — φ12.5 × 25 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole PCB assemblies; available in bulk or bag packing (no terminal forming).
• Compliance — RoHS compliant as specified in the product data.

Typical Applications

• Switching Power Supplies — Used for output filtering and smoothing where low impedance and compact size are required.
• General-Purpose Power Filtering — Suitable for PCB-level decoupling and bulk capacitance in compact power modules and electronic assemblies.
• Compact Power Modules — Fits space-constrained through-hole designs that require a 250 V rating and measurable endurance at elevated temperature.

Unique Advantages

• Compact footprint for tight layouts: The φ12.5 × 25 mm can and 5 mm lead spacing allow designers to add bulk capacitance without a large board area penalty.
• High-voltage capability: 250 V rating supports higher-voltage rails and gives flexibility across power supply topologies that require elevated DC voltage handling.
• Quantified high-temperature endurance: 3000 hours at 105°C provides a documented life expectation for designs operating in warm environments.
• Measured ripple performance: Specified ripple currents at both low and high frequencies help designers size capacitors against AC stress and thermal rise.
• Low loss and controlled leakage: tanδ of 0.15 (20°C, 120 Hz) and leakage current of 320 µA support efficient filtering with predictable power dissipation.
• RoHS compliant: Meets lead-free environmental requirements as stated in the product data.
