UPS1C332MHD

The UPS1C332MHD is a miniature, low-impedance aluminum electrolytic capacitor designed for switching power supplies and general-purpose power filtering. It is a radial‑lead, polarized can that combines compact dimensions with robust ripple handling and a wide operating temperature range.

Key value propositions include low impedance (38 mΩ), a wide temperature range of −55°C to 105°C, and a rated lifetime of 3000 hours at 105°C, making it suitable for compact power applications that require reliable decoupling and smoothing.

Key Features

• Capacitance & Voltage — 3.3 mF capacitance rated at 16 V, with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Low Impedance — Specified impedance of 38 mΩ supports improved ripple performance in power supply circuits.
• Ripple Current Capability — Rated ripple current of 1.653 A at 120 Hz and 1.9 A at 10 kHz, enabling effective filtering under varying switching frequencies.
• Wide Temperature Range — Operating temperature from −55°C to 105°C for stable performance across demanding environments.
• Long Endurance — Rated lifetime of 3000 hours at 105°C under rated DC bias plus rated ripple current.
• Compact Radial Package — Radial lead can with 7.5 mm lead spacing; physical size L: 2.5 × D: 1.6 cm supports space‑constrained PCB layouts.
• Leakage Current Spec — Series leakage current guideline: not more than 0.03CV (µA) after 1 minute’s application of rated voltage at 20°C.
• Regulatory — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Provides bulk smoothing and decoupling for DC outputs and intermediate rails in switching regulators.
• General-Purpose Power Filtering — Suitable for board-level smoothing and energy storage where a compact, polarized electrolytic is required.
• Compact Power Modules — Small can and radial mounting make it appropriate for tightly packed power assemblies and modular power supplies.

Unique Advantages

• High ripple tolerance: Ripple current ratings at both 120 Hz and 10 kHz support effective filtering across low and high switching frequencies.
• Low series impedance: 38 mΩ impedance helps reduce voltage ripple and heat generation in power circuits.
• Wide operating temperature: −55°C to 105°C operation enables use in applications with broad thermal variation.
• Long rated life at elevated temperature: 3000 hours at 105°C provides predictable long-term performance under continuous load.
• Space-efficient radial can: Compact dimensions (L: 2.5 × D: 1.6 cm) and 7.5 mm lead spacing simplify PCB placement in space-constrained designs.
• RoHS compliance: Meets RoHS directive requirements for material compliance.
