UAS2D101MHD

The UAS2D101MHD is a radial-lead aluminum electrolytic capacitor in Nichicon's UAS series, configured as a miniature, high-ripple-current can for general-purpose applications. It delivers 100 µF at 200 V with a wide operating temperature range of −40°C to +105°C and a rated endurance of 2000 hours at 105°C.

Designed for assemblies that require polarized bulk capacitance with elevated ripple handling and robust lifetime performance, this part is offered in a φ12.5 × 30.5 mm radial can with 5 mm lead spacing and is supplied in bulk or bag packing for production use. The device is RoHS compliant and available in mass production.

Key Features

• Electrical Rating — 100 µF capacitance at a 200 V rated voltage with ±20% tolerance, suitable where stable bulk capacitance is required.
• High Ripple Current Capability — Rated ripple current of 430 mA at 120 Hz (low frequency) and 688 mA at 10 kHz (high frequency) to support circuits with significant AC ripple components.
• Leakage and Polarization — Polarized aluminum electrolytic design with a specified leakage current of 900 µA and standard polarized lead orientation.
• Wide Temperature & Endurance — Operates from −40°C to +105°C with an endurance rating of 2000 hours at 105°C under DC bias plus rated ripple current.
• Compact Radial Can Package — φ12.5 × 30.5 mm (D × L) radial, can-style case with 5 mm lead spacing; available in bulk (no terminal forming) or bag packing for assembly flexibility.
• Safety Features — UAS series includes improved safety provisions for abnormally excessive voltage and a pressure relief vent designed to operate without producing flames or dispersion of parts.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in circuits that require 100 µF at 200 V with controlled ripple handling.
• High-ripple power sections — Use where improved ripple current capability (430 mA @120 Hz; 688 mA @10 kHz) is needed to manage AC components on DC rails.
• Wide-temperature systems — Systems operating across −40°C to +105°C that require a capacitor with validated 2000 h endurance at elevated temperature.

Unique Advantages

• Balanced capacitance and voltage rating — 100 µF at 200 V provides substantial energy storage for mid-voltage designs without overspecifying size.
• High-frequency ripple capability — Specified ripple current at both low and high frequencies supports versatile use across switching and linear supplies.
• Proven high-temperature endurance — 2000 hours at 105°C under rated conditions offers predictable life performance for demanding thermal environments.
• Safety-oriented construction — Built-in features to mitigate abnormal over-voltage events and pressure-relief behavior reduce the risk of hazardous failures.
• Production-friendly packaging — Offered in bulk (no terminal forming) or bag packing to suit automated or manual assembly workflows.
• Regulatory compliance — RoHS conformity for markets requiring restricted-substance compliance.
