UAQ2G560MRD3

The UAQ2G560MRD3 is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UAQ series. It delivers 56 µF capacitance at a 400 V rating in a compact φ22 × 25 mm can with 10 mm lead spacing, designed for general-purpose high-voltage applications where high ripple current and wide operating temperature are required.

This part provides a combination of high ripple-current capability and safety features for abnormal voltage conditions, with an operating temperature range of −40 °C to +105 °C and an endurance rating of 2000 hours at 105 °C. Note: this product is End Of Life and is not recommended for new designs.

Key Features

• Capacitance & Tolerance — 56 µF nominal capacitance with tolerance ±20% (measured at 120 Hz, 20 °C).
• High Voltage Rating — Rated for 400 V DC, suitable for higher-voltage DC rail applications.
• Radial Lead Can Package — φ22 × 25 mm can with 10 mm lead spacing (lead spacing tolerance ±0.5 mm); radial-lead configuration for through-hole mounting.
• Ripple Current Performance — Specified low-frequency ripple current 320 mA at 120 Hz and high-frequency ripple current 512 mA at 10 kHz; frequency coefficient rises to 1.60 at 10 kHz.
• Loss & Leakage — Tangent of loss angle (tan δ) maximum 0.15 (20 °C, 120 Hz); leakage current 996 µA (after 1 minute at rated voltage, 20 °C).
• Endurance & Temperature — Endurance 2000 hours at 105 °C under rated voltage plus ripple; operating temperature range −40 °C to +105 °C.
• Safety & Robustness — Improved safety feature for abnormally excessive voltage and pressure-relief vent design to minimize hazardous failure modes.
• Environmental Compliance — RoHS compliant.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose power filtering — 400 V rating and high ripple capability make this part suitable for smoothing and decoupling on high-voltage DC rails in general-purpose equipment.
• Industrial power supplies — Compact radial can and 56 µF capacitance support energy-storage and ripple-management roles in industrial PSUs.
• Power conversion modules — Endurance at 105 °C and high-frequency ripple handling suit applications in converters and related modules where thermal and ripple stresses are present.

Unique Advantages

• 400 V capability: Enables use on higher-voltage DC rails without series arrangements.
• High ripple-current tolerance: Rated ripple currents at low and high frequency allow dependable performance under AC ripple stress.
• Wide operating temperature: −40 °C to +105 °C supports deployment across a broad thermal range while meeting endurance requirements.
• Safety-oriented design: Built-in pressure relief and improved protection against abnormal voltages reduce risk of hazardous failure modes.
• Compact radial form factor: φ22 × 25 mm can with standard 10 mm lead spacing simplifies through-hole PCB layout and replacement in existing designs.
• RoHS compliant: Meets environmental directive requirements for restricted substances.

Why Choose UAQ2G560MRD3?

UAQ2G560MRD3 is positioned for designs that require a 56 µF, 400 V aluminum electrolytic capacitor with proven ripple-current performance, a wide −40 °C to +105 °C operating range, and defined endurance at elevated temperature. Its radial can packaging and 10 mm lead spacing make it straightforward to integrate into through-hole power assemblies and replacement applications.

Because this part is End Of Life and not recommended for new designs, it is most appropriate for maintenance, repair, or continuity-of-supply situations where form, fit, and function match an existing design and the specified electrical and environmental characteristics are required.
