UAS2G820MHD

The UAS2G820MHD is a radial-lead aluminum electrolytic capacitor in a miniature can-style package from Nichicon’s UAS series. It delivers 82 µF capacitance at a 400 V rating with a wide operating temperature range of −40°C to 105°C and is intended for general-purpose electronic applications.

Designed for environments that require high ripple handling and endurance, the UAS2G820MHD combines a compact φ16 × 40 mm package and a 7.5 mm lead spacing with safety features for abnormal voltage events and RoHS compliance.

Key Features

• Electrical Performance — 82 µF capacitance with a rated voltage of 400 V and capacitance tolerance of −20% to +20%.
• Low Loss — tan δ (DF) ≤ 0.15 measured at 20°C, 120 Hz, supporting stable performance in AC and ripple environments.
• High Ripple Current — Rated ripple current of 435 mA at 120 Hz (low frequency) and 696 mA at 10 kHz (high frequency), with frequency coefficients provided in the series datasheet.
• Leakage Current — Measured leakage current 1412 µA; datasheet leakage limit formula is 0.04·C·V + 100 µA (after 1 minute at 20°C).
• Wide Temperature & Endurance — Operating range −40°C to +105°C and endurance of 2000 hours at 105°C under rated bias and ripple conditions.
• Mechanical & Packaging — Compact radial can, φ16 × 40 mm, lead spacing 7.5 mm (±0.5 mm); available in bulk (no terminal forming) / bag packing for production handling.
• Safety Features — Improved safety design for abnormally excessive voltage and pressure-relief vent characteristics documented in the UAS series specifications.
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Filtering and energy storage in circuits needing 400 V rated capacitance with reliable ripple handling across a wide temperature range.
• Power supply smoothing — Bulk decoupling and smoothing where 82 µF at 400 V and high ripple current capability are required.
• Industrial and commercial electronics — Applications operating between −40°C and 105°C that require endurance (2000 h at 105°C) and a compact radial package.

Unique Advantages

• High-voltage capability: 400 V rating supports higher-voltage rails without larger form factors.
• Compact package: φ16 × 40 mm radial can with 7.5 mm lead spacing saves board area while retaining through-hole mounting simplicity.
• Frequency-resilient ripple handling: Specified ripple currents at 120 Hz and 10 kHz and a frequency coefficient table allow predictable performance across a range of switching frequencies.
• Durability under temperature stress: 2000-hour endurance at 105°C provides predictable aging and lifecycle characteristics for long-term designs.
• Built-in safety considerations: Improved abnormal-voltage tolerance and pressure-relief vent features reduce risk in overvoltage scenarios.
• Regulatory compliance: RoHS status ensures compatibility with regulated product lines and supply chains.
