UAQ2G820MHD

The UAQ2G820MHD is an aluminum electrolytic, radial-lead capacitor rated at 82 µF and 400 V. Designed for general-purpose power applications, it offers a compact φ18 × 40 mm can with 7.5 mm lead spacing and bulk or bag packaging for production and repair use.

Built for robust performance under elevated stress, the UAQ series provides wide-temperature operation (−40°C to +105°C), high ripple-current capability and an improved safety feature for abnormally excessive voltage. Note: this part is listed as End Of Life and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a tolerance of ±20% at 120 Hz, rated for 400 V service.
• Wide Temperature Range — Specified for operation from −40°C to +105°C with endurance rated for 2000 hours at 105°C.
• High Ripple Current — Low-frequency ripple current of 420 mA at 120 Hz and high-frequency ripple current of 672 mA at 10 kHz; series frequency coefficients indicate increased allowable ripple at higher frequencies.
• Low Loss & Leakage — Dissipation factor (tan δ) max. 0.15 (20°C, 120 Hz) and measured leakage current consistent with the series specification (product listing: 1,412 µA).
• Safety Construction — Improved safety feature for abnormally excessive voltage; pressure relief vent design to mitigate hazardous failure modes as defined in the series safety performance.
• Radial Can Package — φ18 × 40 mm aluminum can with 7.5 mm lead spacing (±0.5 mm), polarized radial-lead mounting; Pb‑free leadwire and PET sleeve designation in the UAQ series for the φ18 case.
• Regulatory — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power supplies — Smoothing and bulk energy storage where 400 V rating and 82 µF capacitance are required.
• High-voltage DC filtering — Application in DC-link and high-voltage filter circuits that benefit from the part’s specified ripple current capability and wide temperature range.
• Equipment maintenance and spares — Suitable as a replacement component in existing designs using UAQ-series capacitors, where matching size and electrical characteristics are needed.

Unique Advantages

• High ripple handling: Specified ripple currents at 120 Hz and 10 kHz reduce operating stress in high-frequency or high-current ripple environments.
• Wide operating temperature: −40°C to +105°C range and 2000-hour endurance at 105°C support extended operation in elevated-temperature installations.
• Improved abnormal-voltage safety: Series-level safety features and a pressure relief vent help reduce risk under overvoltage conditions.
• Radial, service-friendly package: Standard φ18 can and 7.5 mm lead spacing simplify replacement and PCB retrofits in through-hole assemblies.
• RoHS compliant: Conforms to applicable RoHS directives for environmental compliance.

Why Choose UAQ2G820MHD?

UAQ2G820MHD delivers a straightforward, proven aluminum electrolytic solution for applications that require 82 µF at 400 V with robust ripple-current capability and wide temperature tolerance. Its radial-lead can and defined mechanical dimensions make it practical for repair, spare-part stocking, and designs where the UAQ series form factor and electrical characteristics are already specified.

Please note that this part is designated End Of Life and is not recommended for new product development; it is most appropriate for sustainment, maintenance and replacement scenarios where part-to-part compatibility with the UAQ series is a requirement.
