UAQ2G330MHD

The UAQ2G330MHD is a radial-lead aluminum electrolytic capacitor rated at 33 µF and 400 V. It is a polarized, can-style radial package (φ12.5 × 40L) with 5 mm lead spacing designed for general-purpose electronic applications that require high-voltage capacitance in a compact radial form.

Key engineered characteristics include a wide operating temperature range from −40°C to +105°C, rated endurance of 2000 hours at 105°C under DC bias plus rated ripple current, and built-in safety features for abnormal overvoltage conditions. Note: this part is designated End Of Life.

Key Features

• Capacitance & Rated Voltage — 33 µF nominal capacitance with a 400 V rated voltage, ±20% tolerance at 120 Hz, 20°C.
• Radial Can Package — Axial dimensions φ12.5 × 40 mm with 5 mm lead spacing; radial lead mounting for through-hole PCB assemblies.
• Wide Temperature Range — Operates from −40°C to +105°C, supporting applications that require elevated temperature endurance.
• Endurance — Specified lifetime of 2000 hours at 105°C with DC bias plus rated ripple current; capacitance change, tan δ, and leakage are specified after endurance testing.
• Ripple Current Capability — Rated ripple current of 195 mA at 120 Hz and 312 mA at 10 kHz, with frequency coefficients provided for other frequencies.
• Safety Design — Improved safety feature for abnormally excessive voltage and a pressure relief vent designed to operate without dangerous flame or case dispersion.
• Regulatory Compliance — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Electronics — For circuits that require a polarized 33 µF, 400 V electrolytic capacitor in a radial, through-hole form factor.
• High-Voltage Polarized Circuits — Suited to designs that need a compact polarized capacitor rated up to 400 V with defined endurance at elevated temperature.
• Ripple and Filtering Use — Applicable where specified ripple current handling (195 mA at 120 Hz; 312 mA at 10 kHz) is required for smoothing and filtering functions.

Unique Advantages

• High-Voltage Capability: 400 V rating enables use in higher-voltage circuits where lower-voltage electrolytics are not acceptable.
• Compact Radial Form: φ12.5 × 40 mm can with 5 mm lead spacing provides a space-efficient through-hole solution for board-level assemblies.
• Temperature and Endurance Specified: −40°C to +105°C operating range and 2000 hours endurance at 105°C give predictable performance in elevated-temperature environments.
• Measured Ripple Ratings: Published ripple current values at 120 Hz and 10 kHz and frequency coefficients allow designers to match capacitor selection to operating frequency.
• Built-in Safety Measures: Pressure relief vent and enhanced safety for abnormal overvoltage conditions reduce risk of hazardous failure modes.
• RoHS Compliant: Conforms to RoHS directives, supporting regulatory requirements for restricted substances.
