UPS2D221MHD

The UPS2D221MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial‑lead can designed for power filtering in switching power supplies and general‑purpose equipment. It pairs 220 µF capacitance with a high rated voltage and a compact φ18 × 40 mm package to deliver stable filtering and decoupling across a wide temperature range.

Engineered for long endurance under elevated temperatures, this Nichicon UPS series part offers low loss (tan δ) and measurable ripple‑current capability for robust performance in board‑level power rails and supply circuits.

Key Features

• Capacitance and Voltage — 220 µF nominal capacitance with a rated voltage of 100 V and a capacitance tolerance of −20% to +20% for predictable bulk energy storage and filtering.
• Low Loss / Frequency Performance — Loss tangent (tan δ) of 0.09 measured at 20°C, 120 Hz, supporting efficient filtering with controlled dissipation.
• Ripple Current Capability — Specified low‑frequency ripple current of 415.8 mA (120 Hz) and high‑frequency ripple current of 2120 mA for handling AC stress from switching regulators.
• Wide Temperature Range — Rated for operation from −55°C to +105°C to accommodate demanding thermal environments.
• Long Endurance — 3000 hours life at 105°C under rated conditions, meeting prolonged duty requirements in power electronics.
• Radial Lead, Compact Package — φ18 × 40 mm can, 7.5 mm lead spacing (±0.5 mm) in a through‑hole radial lead form for simple PCB assembly and secure mechanical mounting.
• Leakage and Reliability — Leakage current specified (product datum 4158 µA) and designed for stable performance after endurance testing consistent with the UPS series characteristics.
• RoHS Compliant — Constructed to meet RoHS requirements.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering for board‑level switch‑mode power supplies, leveraging the UPS series’ focus on low impedance and miniature size.
• General‑Purpose Power Filtering — Decoupling and energy storage in general electronic equipment requiring a 100 V rated, high‑temperature capacitor.
• Embedded & Industrial Power Rails — Through‑hole radial package provides reliable mounting for power rails in embedded devices and industrial control equipment.

Unique Advantages

• High Voltage Capability: 100 V rating enables use on higher DC rails while maintaining compact form factor.
• Compact, Serviceable Form Factor: φ18 × 40 mm radial can provides a small footprint and straightforward through‑hole installation.
• Designed for Elevated Temperatures: −55°C to +105°C operating range and 3000 h endurance at 105°C support long service life in thermally stressed environments.
• Measurable Ripple Handling: Explicit low‑ and high‑frequency ripple current figures allow engineers to size and verify thermal and lifetime margins.
• Low Dissipation: Low tan δ at 120 Hz (0.09) reduces power loss in filtering applications, improving overall supply efficiency.
• Standard Packaging Options: Available in bulk or bag packing for flexible procurement and assembly workflows.
