UCA2E330MHD

The UCA2E330MHD is a polarized aluminum electrolytic capacitor in a radial can package designed for general-purpose use where high ripple tolerance and long operational life are required. It delivers 33 µF at 250 V in a compact radial-lead form factor suited to power supply and ballast applications.

Key value propositions include high rated ripple current, long-life endurance at elevated temperature, and a compact footprint for space-constrained board layouts. The part is RoHS compliant.

Key Features

• Capacitance and Voltage — 33 µF rated capacitance at 250 V.
• High ripple current — Rated ripple current of 315 mA at 120 Hz and 630 mA at 100 kHz, supporting circuits with significant AC content on DC rails.
• Long operational life — Load-life specification of 12000 hours at 105°C (series specification).
• Compact radial can package — Radial lead, can-style package with lead spacing 5 mm and size L: 2 × D: 1.25 cm, for easy through-hole mounting.
• Temperature range — Operates from −25°C to +105°C.
• Tolerance and polarity — Capacitance tolerance ±20% and polarized construction.
• Regulatory — RoHS compliant.

Typical Applications

• Power supplies — Smoothing and bulk decoupling where high ripple currents are present on DC rails.
• Ballast circuits — Use in lighting ballast designs as indicated for the UCA series.
• General-purpose electronic equipment — Filtering and energy storage in compact through-hole assemblies.

Unique Advantages

• High ripple handling — Explicit ripple ratings at 120 Hz and 100 kHz allow designers to select the part for circuits with significant AC ripple without over-specifying.
• Proven long-life endurance — Specified endurance of 12000 hours at 105°C supports extended field life in high-temperature environments.
• Space-efficient radial form — Small can dimensions and 5 mm lead spacing simplify replacement of legacy through-hole designs and save PCB area.
• Wide operating temperature window — −25°C to +105°C rating covers many industrial and commercial operating environments.
• RoHS compliance — Meets directive requirements for lead-free manufacturing environments.
