UAS2G330MHD

The UAS2G330MHD is a miniature radial-lead aluminum electrolytic capacitor designed for general-purpose power circuitry. It provides a 33 µF capacitance at a 400 V rating in a compact φ16 × 20 mm can with 7.5 mm lead spacing, combining high-voltage capability with a wide operating temperature range.

Engineered for reliability, the part offers high ripple current handling, an improved safety feature for abnormal voltage conditions, and RoHS compliance—making it suitable for a broad set of higher-voltage electronic designs that require polarized bulk capacitance.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance with a 400 V DC rating and ±20% tolerance at 120 Hz, 20°C.
• High ripple capability — Rated ripple current of 225 mA at 120 Hz (low frequency) and 360 mA at 10 kHz (high frequency), with frequency coefficients provided for other operating frequencies.
• Wide temperature range — Specified for operation from −40°C to +105°C for use across a wide range of ambient conditions.
• Electrical loss and leakage — Maximum tan δ of 0.15 (measured at 120 Hz, 20°C) and a leakage current of 628 µA (measured after 1 minute at 20°C under rated voltage).
• Endurance — Rated for 2000 hours at 105°C under DC bias plus rated ripple current; capacitance, tan δ and leakage meet specified endurance limits after the test.
• Safety features — Improved safety design for abnormally excessive voltage and a pressure relief vent that operates under abnormal conditions to avoid dangerous outcomes.
• Package & mounting — Miniature radial, can-type package (φ16 × 20 mm), radial lead mounting, lead spacing 7.5 mm; available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power circuitry — Polarized bulk capacitance for smoothing and filtering in higher-voltage circuits where a 400 V rating is required.
• High-voltage power modules — Use in circuits that require a compact 33 µF capacitor with substantial ripple handling at both low and high frequencies.
• Industrial and commercial equipment — Applications that benefit from a wide −40°C to +105°C operating range and specified endurance at elevated temperature.

Unique Advantages

• 400 V rating for higher-voltage designs: Enables use in circuits that require elevated DC working voltage while maintaining compact size.
• Compact footprint: φ16 × 20 mm can and 7.5 mm lead spacing make the component space-efficient for dense PCBs or assemblies.
• Measured ripple performance: Defined ripple current values at 120 Hz and 10 kHz allow straightforward thermal and lifetime planning for power designs.
• Wide operating temperature and proven endurance: −40°C to +105°C range plus 2000 hours at 105°C under bias delivers predictable behavior in demanding environments.
• Built-in safety measures: Improved abnormal-voltage protection and a pressure relief vent reduce risk under fault conditions.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
