UPS2G330MHD

The UPS2G330MHD is an aluminum electrolytic capacitor in Nichicon’s UPS series, engineered as a miniature, low-impedance energy storage component for power-supply applications. It is a polarized, radial-lead can designed for general-purpose use and specifically noted for switching power supplies.

Key attributes include a 33 µF capacitance at a 400 V rating, RoHS compliance, a compact radial package, and a wide operating temperature range suited to demanding power environments.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance, suitable for higher-voltage power circuits.
• Low Impedance for Power Filtering — Series designation emphasizes low impedance; rated ripple currents are 140 mA at 120 Hz and 224 mA at 10 kHz, supporting effective smoothing in switching supplies.
• Wide Operating Temperature — Specified operating range of −40 °C to +105 °C to cover a broad set of ambient conditions.
• Endurance — Rated for 3000 hours at 105 °C, providing predictable life performance under elevated-temperature bias conditions.
• Miniature Radial Package — Radial lead, can-style package with 7.5 mm lead spacing and compact dimensions of L: 3.05 × D: 1.6 cm, enabling space-conscious PCB layouts.
• Compliance — RoHS compliant to the directives listed in the product description.

Typical Applications

• Switching Power Supplies — Energy storage and output filtering where low impedance and 400 V capability improve regulation and ripple suppression.
• General-Purpose Power Filtering — Bulk and decoupling capacitor for a range of power-supply designs labeled as general purpose in the product data.
• Compact Power Modules — Miniature L: 3.05 × D: 1.6 cm radial can is suited to designs with constrained board space.

Unique Advantages

• High-Voltage Capability: 400 V rating enables use in higher-voltage stages of power supplies without changing topology.
• Low-Impedance Performance: Specified ripple current ratings at 120 Hz and 10 kHz (140 mA and 224 mA respectively) support effective filtering across common power frequencies.
• Compact Footprint: Small radial can and 7.5 mm lead spacing reduce PCB area compared with larger electrolytic options.
• Wide Thermal Range and Endurance: −40 °C to +105 °C operating range and 3000 hours at 105 °C endurance provide predictable behavior in elevated-temperature applications.
• Regulatory Compliance: RoHS-compliant construction supports use in designs targeting restricted-substance requirements.
