UPS1H2R2MDD

The UPS1H2R2MDD is a radial‑lead aluminum electrolytic capacitor in Nichicon's UPS series, offered in a miniature φ5×11 mm can. Designed for general‑purpose and power electronics use, this part is part of a low‑impedance series intended for switching power supplies and compact power modules.

With a rated voltage of 50 V, a capacitance of 2.2 µF and a wide operating temperature range from −55 °C to 105 °C, the capacitor provides stable decoupling and smoothing performance in space‑constrained designs requiring elevated temperature endurance.

Key Features

• Electrical Performance — 2.2 µF capacitance with ±20% tolerance and a tangent of loss angle (tan δ) of 0.10 measured at 20 °C, 120 Hz, enabling predictable AC behavior in decoupling applications.
• Voltage Rating — 50 V rated voltage suitable for a variety of mid‑voltage power rails and supply circuits.
• Ripple Handling — Low‑frequency ripple current 9.35 mA at 120 Hz and high‑frequency ripple current 55 mA at 10 kHz, enabling effective smoothing across frequency ranges typical in switch‑mode power supplies.
• Leakage and Reliability — Specified leakage current of 4 µA (typical measurement condition), and an endurance rating of 2000 hours at 105 °C, providing reliable long‑term operation under elevated temperature stress.
• Compact Radial Package — Radial lead, can package sized φ5×11 mm (L: 1.1 × D: 0.5 cm) with 2.0 mm lead spacing (±0.5 mm), suited for through‑hole mounting in compact boards.
• Packaging Options & Compliance — Available in bulk (no terminal forming) or bag packing; RoHS‑compliant.

Typical Applications

• Switching Power Supplies — Series‑level design emphasizes low impedance for decoupling and smoothing in compact SMPS designs.
• General Purpose Power Filtering — Used for bulk decoupling and ripple suppression on mid‑voltage rails where a compact radial capacitor is required.
• Compact Power Modules — Small can size (φ5×11 mm) and radial mounting make it suitable for space‑limited power assemblies and module platforms.

Unique Advantages

• Miniature low‑impedance design: Part of a UPS series specified for low impedance, enabling effective decoupling in tight layouts.
• wide temperature capability: Rated for −55 °C to 105 °C with 2000 hours endurance at 105 °C, supporting reliable operation in elevated temperature environments.
• Frequency‑span ripple performance: Specified ripple currents for both low and high frequencies (9.35 mA @120 Hz, 55 mA @10 kHz) help manage ripple across switching and high‑frequency domains.
• Low leakage current: 4 µA leakage supports low standby loss and stable bias conditions in power circuits.
• Compact through‑hole footprint: φ5×11 mm can with 2.0 mm lead spacing simplifies layout for dense boards while retaining the robustness of radial lead mounting.
• RoHS compliant and packaged for production: Available in bulk or bag packing to match prototyping and production line needs.
