UPS2G101MRD

The UPS2G101MRD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon’s UPS series designed for switching power supply and general-purpose power filtering applications. It is a polarized, high-reliability component specified at 100 µF and 100 V with a compact φ12.5 × 20 mm can and 10 mm lead spacing.

Engineered for elevated-temperature endurance, this part delivers 3,000 hours of rated-life performance at 105°C, low loss (tanδ = 0.08 at 20°C, 120 Hz), and controlled leakage for robust power-stage decoupling and smoothing in demanding environments.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C, rated for 100 V application voltage.
• Thermal Endurance — Rated for operation across –55°C to +105°C with 3,000 hours endurance at 105°C under rated ripple and DC bias conditions.
• Low Loss & Leakage — tanδ (DF) of 0.08 measured at 20°C, 120 Hz, and a leakage current specified at 300 µA, supporting efficient energy storage with controlled self-discharge.
• Ripple Current Capability — Low-frequency ripple current of 300 mA and high-frequency ripple current of 560 mA to support switching supply ripple handling across frequency ranges.
• Radial Lead, Through-Hole Mounting — Standard radial-lead can (φ12.5 × 20 mm) with 10 mm lead spacing (±0.5 mm) for easy through-hole assembly and prototyping.
• Regulatory — RoHS-compliant construction for use in assemblies requiring restricted-substance compliance.
• Packaging & Status — Available in bulk (no terminal forming) or bag packing; current part status: End Of Life.

Typical Applications

• Switching Power Supplies — Output smoothing and decoupling where a compact, high-voltage electrolytic is required for energy storage and ripple attenuation.
• General Purpose Power Filtering — Bulk decoupling and input smoothing in bench supplies, industrial power modules, and power-management circuits.
• Power Conversion Modules — Local energy reservoir for DC–DC converter stages needing rated performance at elevated temperatures.

Unique Advantages

• Compact High-Voltage Option: 100 µF at 100 V in a φ12.5 × 20 mm can provides a space-efficient solution for high-voltage bulk capacitance requirements.
• High-Temperature Reliability: 3,000-hour endurance at 105°C supports extended operation in thermally demanding power electronics designs.
• Measured Performance Metrics: Low dissipation factor (tanδ = 0.08 at 120 Hz) and defined leakage current (300 µA) give predictable behavior for design margin calculations.
• Through-Hole Convenience: Radial-lead package with 10 mm spacing simplifies prototype builds and replacement in legacy board layouts.
• RoHS Compliance: Meets RoHS directive requirements for environments with restricted substance mandates.
