UAS2G101MHD

The UAS2G101MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UAS series. It delivers 100 µF capacitance at a 400 V rating in a compact φ18 × 35.5 mm radial-can package with 7.5 mm lead spacing for through-hole assembly.

Designed for general-purpose use, the capacitor combines high ripple capability, a wide operating temperature range of -40 °C to +105 °C, and endurance characteristics that support sustained operation in demanding thermal environments.

Key Features

• Electrical Performance — 100 µF nominal capacitance with a tolerance of ±20% and a 400 V rated voltage.
• High Ripple Current — Rated ripple current of 490 mA at 120 Hz and 784 mA at 10 kHz, enabling effective smoothing across a range of frequencies.
• Wide Temperature & Endurance — Operates from -40 °C to +105 °C with a rated lifetime of 2000 hours at 105 °C under DC bias plus rated ripple current.
• Safety & Reliability — UAS series features include an improved safety design for abnormally excessive voltage and a pressure relief vent to reduce hazardous failure modes.
• Radial Through-Hole Package — φ18 × 35.5 mm can, 7.5 mm lead spacing, radial lead mounting type for straightforward PCB assembly and replacement.
• Compliance — RoHS compliant material construction.
• Leakage and Loss Characteristics — Leakage current meets the datasheet formula (0.04CV + 100 μA or less after 1 minute at 20 °C) and tan δ rated at 0.15 (for 400 V at 120 Hz, 20 °C).

Typical Applications

• General-purpose power filtering — Bulk smoothing and ripple reduction where 100 µF at 400 V and robust ripple handling are required.
• Industrial power equipment — Energy buffering and decoupling in assemblies that must operate across -40 °C to +105 °C and meet endurance demands (2000 h at 105 °C).
• Commercial and consumer electronics — Through-hole designs needing a compact radial-can capacitor with high-voltage rating and RoHS compliance.

Unique Advantages

• High-voltage capability: 400 V rating supports designs with elevated DC bus voltages.
• Compact, serviceable form factor: φ18 × 35.5 mm radial can and 7.5 mm lead spacing simplify layout and replacement in through-hole assemblies.
• Frequency-aware ripple performance: Strong ripple current ratings at 120 Hz and 10 kHz (490 mA and 784 mA respectively) and frequency coefficient behavior for reliable filtering across frequencies.
• Extended endurance at elevated temperature: 2000 hours at 105 °C under rated conditions provides predictable life for sustained thermal stress.
• Built-in safety considerations: Improved permissible abnormal voltage design and a pressure relief vent reduce the risk of hazardous failure modes.
• Regulatory compliance: RoHS compliant materials align with environmental requirements.
