UPS1C222MHD

The UPS1C222MHD is a miniature, low‑impedance aluminum electrolytic capacitor in a radial can package, designed for switching power supplies and general‑purpose power applications. Manufactured by Nichicon as part of the UPS series, it delivers compact energy storage with a wide operating temperature range and RoHS compliance.

Key attributes include a 2.2 mF capacitance at 16 V, polarized radial‑lead construction, and electrical characteristics targeted at power‑stage decoupling and ripple handling in space‑constrained assemblies.

Key Features

• Capacitance & Voltage — 2.2 mF capacitance rated at 16 V for bulk decoupling and energy storage in low‑voltage power rails.
• Low Impedance — Specified impedance of 57 mΩ supports lower ESR in power path applications to reduce voltage ripple.
• Ripple Current Capability — Rated ripple current of 1.349 A at 120 Hz and 1.55 A at 10 kHz for AC stress in switching power environments.
• Wide Temperature Range — Operating temperature range of −55 °C to +105 °C to support demanding thermal environments.
• Long Endurance — Rated lifetime of 3000 hours at 105 °C under specified conditions, with endurance characteristics defined in the UPS series datasheet.
• Compact Radial Can Package — Radial, can‑style package with radial leads, 5 mm lead spacing, and dimensions L: 2.5 × D: 1.25 cm for space‑efficient PCB layouts.
• Polarized — Designed as a polarized aluminum electrolytic capacitor for DC power applications.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk decoupling and ripple suppression in DC‑DC converters and switch‑mode power stages where compact, low‑ESR capacitors are required.
• General‑Purpose Power Circuits — Energy storage and smoothing in a wide range of general electronic power designs that accept a polarized radial electrolytic capacitor.
• Radial‑Lead Assemblies — Through‑hole, radial lead mounting for power modules and assemblies requiring a can‑style capacitor with 5 mm lead spacing.

Unique Advantages

• Space‑efficient footprint: Compact dimensions (L: 2.5 × D: 1.25 cm) enable use in tight layouts without sacrificing capacitance.
• Designed for low ESR: 57 mΩ impedance reduces voltage drop and heat under ripple, improving performance in power paths.
• Broad thermal operating range: −55 °C to +105 °C supports deployment across varied ambient conditions.
• Measured ripple handling: Defined ripple current ratings at 120 Hz and 10 kHz provide clear guidance for AC stress capability in switching environments.
• Endurance at elevated temperature: 3000 hours at 105 °C specifies long‑term electrical stability under rated conditions.
• Regulatory compliance: RoHS compliance for use in assemblies that require restricted‑substance conformance.
