UAS2G560MHD

The UAS2G560MHD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UAS series. It provides 56 µF capacitance at a 400 V rating in a compact φ16 × 30.5 mm can with 7.5 mm lead spacing, designed for general-purpose electronic applications.

Designed for wide operating temperatures and elevated ripple conditions, the capacitor offers a -40 °C to 105 °C operating range, 2,000 hours endurance at 105 °C, RoHS compliance, and an improved safety feature for abnormally excessive voltage situations.

Key Features

• Rated Capacitance and Voltage: 56 µF at 400 V — suitable for DC link and bulk energy storage in high-voltage general-purpose circuits.
• Wide Temperature Range & Endurance: Operates from -40 °C to 105 °C with a rated life of 2,000 hours at 105 °C under DC bias plus rated ripple current.
• High Ripple Current Capability: Low-frequency ripple current 340 mA (120 Hz) and high-frequency ripple current 544 mA (10 kHz), enabling effective smoothing under a range of operating frequencies.
• Leakage Current Performance: Specified leakage current of 996 µA (measured after 1 minute at 20 °C), consistent with the series formula 0.04CV + 100 µA.
• Loss Tangent (tan δ): tan δ max 0.15 at 20 °C, 120 Hz for the 400 V rating, providing predictable dissipation characteristics.
• Compact Radial Can Package: φ16 × 30.5 mm can with radial leads and 7.5 mm lead spacing (±0.5 mm tolerance); available in bulk or bag packing.
• Safety Feature: UAS series includes an improved safety design for permissible abnormal voltage conditions; pressure relief vent operates without hazardous outcomes under the specified test conditions.
• Regulatory Compliance: RoHS-compliant construction.

Typical Applications

• General-purpose power supplies: Bulk filtering and smoothing in 400 V DC circuits where compact size and high ripple handling are required.
• DC link and energy storage: Local energy storage and decoupling in medium-voltage assemblies leveraging the 56 µF capacitance and high ripple current capacity.
• Industrial electronics: Use in general-purpose industrial control and power conversion equipment operating across a wide temperature range (-40 °C to 105 °C).

Unique Advantages

• 400 V Rating in a Miniature Can: Enables high-voltage designs without a large footprint, supporting compact board layouts.
• High Ripple Endurance: Rated ripple currents at both 120 Hz and 10 kHz provide versatility for low- and high-frequency ripple environments.
• Wide Temperature & Proven Endurance: -40 °C to 105 °C operating range with 2,000 hours endurance at 105 °C helps ensure stability in thermally demanding applications.
• Predictable Leakage and Loss Characteristics: Specified leakage current (996 µA) and tan δ (0.15) permit straightforward thermal and leakage budgeting in designs.
• Safety-conscious Design: Improved abnormal-voltage safety features reduce the risk of hazardous failure modes under specified conditions.
• RoHS Compliance: Meets regulatory requirements for lead-free assemblies.
