UPS1J222MHD

The UPS1J222MHD is a miniature aluminum electrolytic capacitor from Nichicon’s UPS series, designed for radial‑lead mounting in compact power electronics. Built for switching power supplies and general‑purpose power filtering, it combines low impedance and high ripple handling in a small can package.

Key value comes from its 2.2 mF capacitance at 63 V rating, 32 mΩ impedance, and wide operating temperature range, offering a reliable choice where space, ripple tolerance and thermal endurance matter.

Key Features

• Capacitance & Voltage — 2.2 mF capacitance rated at 63 V suitable for energy storage and decoupling in power rails; tolerance ±20%.
• Low Impedance — Specified impedance of 32 mΩ to help minimize voltage ripple and improve transient response in switching circuits.
• High Ripple Current Handling — Rated ripple current of 1.844 A at 120 Hz and 2.12 A at 10 kHz, supporting both low‑ and high‑frequency switching environments.
• Wide Temperature & Endurance — Operating range from −55°C to +105°C with an endurance rating of 3000 hours at 105°C under rated conditions.
• Compact Radial Can Package — Radial, can‑style package with radial lead mounting and 7.5 mm lead spacing; physical size L: 4 × D: 1.8 cm for space‑constrained layouts.
• Polarized — Conventional polarized aluminum electrolytic design for common power supply topologies.
• RoHS Compliant — Manufactured to meet RoHS requirements.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where low impedance and rated ripple current reduce output ripple and improve regulation.
• Power Conversion Modules — Energy storage and decoupling in compact DC‑DC converters and power modules.
• General‑Purpose Power Filtering — Decoupling and smoothing on power rails across industrial and consumer power electronics.

Unique Advantages

• Low impedance performance: 32 mΩ impedance helps control voltage ripple and supports stable converter operation.
• Frequency‑range ripple capability: Ripple current ratings provided for both 120 Hz (1.844 A) and 10 kHz (2.12 A) support mixed‑frequency switching designs.
• Compact footprint: Small radial can (L: 4 × D: 1.8 cm) and 7.5 mm lead spacing enable integration into space‑limited PCBs.
• Wide thermal tolerance and proven endurance: −55°C to +105°C operating range with 3000 hours life at 105°C for reliability in elevated‑temperature environments.
• RoHS compliant manufacturing: Aligns with environmental requirements for modern electronics production.
