UCA2D330MHD

The UCA2D330MHD is a miniature, polarized aluminum electrolytic capacitor in a radial can package designed for high ripple‑current duty and extended operational life. It is intended for general‑purpose electronic use and is particularly suited to power supply and ballast applications.

Key electrical characteristics include 33 µF capacitance at a 200 V rating, high ripple handling up to the specified limits, and long life under elevated temperature stress—supporting continuous operation at +105°C per its endurance rating. The part is RoHS‑compliant.

Key Features

• Electrical performance — 33 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C; polarized design for DC energy storage and smoothing.
• Rated voltage — 200 V working voltage suitable for higher‑voltage power circuits within the series range.
• High ripple‑current capability — Specified ripple handling of 300 mA at 120 Hz and 600 mA at 100 kHz, enabling improved thermal margin in high‑ripple environments.
• Long life and endurance — Rated for 12,000 hours at +105°C (endurance conditions defined per series specifications), with capacitance change, tan δ and leakage current limits specified after test.
• Reliability parameters — Leakage current specified as ≤ 0.04CV + 100 µA (after 1 minute at 20°C); tan δ limit of 0.15 at 200 V (measured at 120 Hz, 20°C).
• Package and mounting — Radial lead, can style package with 5 mm lead spacing for through‑hole mounting and straightforward assembly.
• Operating temperature range — −25°C to +105°C, supporting elevated‑temperature applications.
• Environmental compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).
• Frequency ripple scaling — Frequency coefficients available for rated ripple current (e.g., 0.50 at 120 Hz, 1.00 at 100 kHz) to assist ripple current derating across frequency.

Typical Applications

• Power supplies — DC link, smoothing and filtering where a compact, high‑voltage polarized capacitor with elevated ripple capability is required.
• Ballasts — Energy storage and ripple management in ballast circuits that experience continuous high‑temperature operation.
• General‑purpose industrial electronics — Filtering and decoupling in higher‑voltage circuits that require long life and predictable leakage and dissipation behavior.

Unique Advantages

• Designed for elevated‑temperature endurance — 12,000‑hour rating at +105°C provides predictable life performance for sustained high‑temperature applications.
• High ripple capability across frequency — Clear ripple‑current specifications at 120 Hz and 100 kHz plus frequency coefficients allow engineers to size and derate reliably for their application bandwidth.
• Compact radial can package — Radial lead mounting with 5 mm lead spacing simplifies PCB layout for through‑hole assemblies while preserving board density.
• Measurable electrical limits — Specified leakage current formula and tan δ limits support thermal and loss budgeting during design and validation.
• Regulatory compliance — RoHS conformity supports deployments that must meet current lead‑restriction regulations.
