UPS1E332MHD

The UPS1E332MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPS series, designed for low-impedance power decoupling and smoothing in general-purpose and switching power supply applications. It combines a 3.3 mF nominal capacitance with a 25 V rated voltage and radial-lead packaging to deliver compact, durable energy storage for board-level power rails.

Key value propositions include low impedance (33 mΩ), robust ripple-current capability across low and high frequencies, and a wide operating temperature range of −55°C to +105°C with a rated endurance of 3000 hours at 105°C.

Key Features

• Capacitance & Voltage — 3.3 mF capacitance rated at 25 V for energy storage and decoupling on low-voltage power rails.
• Low Impedance — 33 mΩ impedance supports stable voltage filtering and minimizes voltage droop under dynamic load.
• High Ripple Current Handling — Rated ripple current of 2.045 A at 120 Hz and 2.35 A at 10 kHz to support switching supply and pulse-load environments.
• Wide Temperature Range & Endurance — Operates from −55°C to +105°C and meets endurance of 3000 hours at 105°C under rated bias and ripple conditions.
• Radial Lead, Can Package — Radial-lead mounting with a compact can-style package (size L: 3.05 × D: 1.6 cm) for through-hole PCB implementations; lead spacing is 7.5 mm.
• Polarized Construction — Polarized aluminum electrolytic design for correct orientation in DC power circuits.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Switching Power Supplies — Local bulk and output filtering where low impedance and high ripple capability improve transient response and reduce output ripple.
• General Power Filtering — Bulk decoupling and smoothing on board-level DC rails in consumer and industrial electronics.
• Industrial Power Modules — Energy storage and filtering in compact power modules that require wide temperature operation and long endurance.

Unique Advantages

• Compact Energy Density — 3.3 mF in a small radial can (3.05 × 1.6 cm) helps reduce board area while maintaining required capacitance.
• Low ESR/Impedance — 33 mΩ impedance supports lower heat generation and better voltage stability under load, simplifying thermal management.
• Frequency-robust Ripple Performance — Specified ripple current at both 120 Hz and 10 kHz provides predictable behavior across switching and low-frequency conditions.
• Designed for Harsh Temperatures — Rated to operate from −55°C to +105°C with a 3000-hour life at 105°C, supporting long-term reliability in demanding environments.
• Through-hole Mounting Simplicity — Radial lead configuration and defined 7.5 mm lead spacing ease PCB layout and manual or wave-solder assembly.
• Regulatory Compliance — RoHS compliance supports use in regulated markets and assemblies.
