UPS1A332MHD

The UPS1A332MHD is a miniature, low‑impedance aluminum electrolytic capacitor from Nichicon's UPS series, designed for radial‑lead through‑hole mounting. It is intended for switching power supplies and other general‑purpose applications that require compact bulk capacitance and robust ripple handling at low voltages.

Key value points include a 3.3 mF capacitance at 10 V, a wide operating temperature range (−55 °C to +105 °C), and a low impedance characteristic that supports effective smoothing and decoupling in compact power circuits.

Key Features

• Capacitance & Voltage — 3.3 mF capacitance rated at 10 V with a tolerance of −20% to +20% for predictable bulk energy storage in low‑voltage designs.
• Low Impedance — Specified impedance of 57 mΩ, enabling improved ripple attenuation and lower ESR losses in power circuits.
• Wide Temperature Range & Endurance — Operates from −55 °C to +105 °C with a rated lifetime of 3000 hours at 105 °C under DC bias plus rated ripple current.
• High Ripple Current Capability — Rated ripple current of 1.349 A at 120 Hz and 1.55 A at 10 kHz to support high‑ripple switching environments.
• Radial Lead, Compact Package — Radial, can‑style package with 5 mm lead spacing and physical dimensions L: 2.5 × D: 1.25 cm for space‑constrained boards.
• RoHS Compliant — Manufactured to meet RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where compact size and low impedance improve regulation and transient response.
• General‑Purpose Power Filtering — Decoupling and energy storage in a variety of low‑voltage DC circuits labeled as general purpose in the product data.
• High‑ripple Environments — Applications that require sustained ripple current handling at both low and high frequencies, supported by the specified ripple current ratings.

Unique Advantages

• Compact bulk capacitance: 3.3 mF in a small radial can (L: 2.5 × D: 1.25 cm) reduces board area for bulk energy storage.
• Low ESR performance: 57 mΩ impedance supports lower losses and better thermal performance in power conversion stages.
• Wide operating temperature: −55 °C to +105 °C rating extends usability across demanding environmental ranges.
• Proven endurance at elevated temperature: 3000 hours at 105 °C under rated conditions provides predictable long‑term behavior for thermal stress applications.
• High ripple capability: Specified ripple current at 120 Hz and 10 kHz helps ensure reliable operation in switching and high‑frequency circuits.
• RoHS compliance: Manufactured in accordance with applicable RoHS directives for regulatory alignment.
