UPS2A100MED

The UPS2A100MED is a miniature, polarized aluminum electrolytic capacitor from Nichicon designed for switching power supplies and general-purpose electronic power filtering. It delivers a 100 V rated voltage in a compact radial‑lead can, offering low impedance characteristics and a wide operating temperature range for demanding power‑rail applications.

Key value propositions include a high working voltage (100 V), compact footprint (L: 1.1 × D: 0.63 cm), radial through‑hole mounting, and RoHS compliance—making it suitable for compact, high‑voltage power designs that require reliable ripple handling and extended thermal endurance.

Key Features

• Rated Voltage & Capacitance — 100 V rated voltage with 10 µF capacitance and ±20% tolerance, suitable for high‑voltage smoothing and energy‑storage tasks.
• Compact Radial Package — Radial, can‑style package with radial lead mounting and 2.5 mm lead spacing; small footprint sized L: 1.1 × D: 0.63 cm for space‑constrained boards.
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C to support a broad range of ambient and elevated‑temperature environments.
• Endurance at Elevated Temperature — Designed for 2000 hours of operation at 105 °C, supporting long‑term stability under thermal stress.
• Low Impedance & Ripple Handling — Low impedance design with specified ripple current of 22.1 mA at 120 Hz and 130 mA at 10 kHz, helping reduce AC voltage ripple on power rails.
• Leakage & Loss Characteristics — Leakage current specified by series guideline: after 1 minute at rated voltage and 20 °C, leakage current ≤ 0.03CV (µA). Loss tangent (tan δ) for the UPS series at 100 V is specified up to 0.08 (measured at 120 Hz, 20 °C).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulated product builds.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where a compact, high‑voltage polarized capacitor is required.
• DC‑DC Converters & Power Rails — Local decoupling and ripple reduction on high‑voltage rails in board‑level power subsystems.
• Industrial and Control Electronics — Energy storage and filtering in control modules and power distribution circuits operating across wide temperature ranges.

Unique Advantages

• High Voltage Capability: 100 V rating enables use in higher‑voltage power rails without changing capacitor type.
• Miniature Footprint: Small L × D dimensions (1.1 × 0.63 cm) reduce board space for compact power designs.
• Wide Operating Temperature: −55 °C to +105 °C rating broadens usable environments and reduces the need for additional thermal management.
• Designed for Ripple Duty: Specified ripple current at both low and high frequencies (22.1 mA at 120 Hz; 130 mA at 10 kHz) supports filtering in switching applications.
• Clear Loss and Leakage Specs: Series loss tangent and leakage current formula (≤ 0.03CV µA after 1 minute at 20 °C) provide predictable electrical behavior for design verification.
• RoHS Compliant: Meets current RoHS directives for regulated product assemblies.
