UPJ1A222MHD

The UPJ1A222MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a polarized, radial-lead device specified at 2200 µF (2.2 mF) and 10 V, designed for demanding low-voltage power applications.

Engineered for low impedance and sustained performance, this part provides high ripple-handling capability and long endurance, making it well suited for switching power supplies and general-purpose power filtering where durability at elevated temperature is required.

Key Features

• Electrical Rating — 2.2 mF capacitance at a rated voltage of 10 V with capacitance tolerance -20%~20%.
• Low Loss Characteristics — Tangent of loss angle (tanδ) measured at 20°C, 120 Hz is 0.21, supporting stable performance in power smoothing applications.
• High Ripple Handling — Low-frequency ripple current 1.377 A (120 Hz) and high-frequency ripple current 1.53 A (1 kHz) for robust filtering in switching environments.
• Leakage Current — Specified leakage current of 660 µA after rated voltage application, enabling predictable standby and operating behavior.
• High Endurance — Rated life of 5000 hours at 105°C, providing long-term stability under sustained load at elevated temperature.
• Package & Mounting — Radial lead, can-type package with size φ12.5 × 25 mm (D × L), lead spacing 5 mm (±0.5 mm), for through-hole mounting and straightforward PCB integration.
• Environmental Compliance & Availability — RoHS compliant and currently in mass production; available in bulk or bag packing (no terminal forming).

Typical Applications

• Switching Power Supplies — Provides low-impedance bulk capacitance and high ripple handling for output smoothing and stability in DC–DC converters.
• Power Filtering and Decoupling — Used on low-voltage power rails to reduce ripple and stabilize supply voltage for embedded systems and control electronics.
• Industrial Power Modules — Suitable for general-purpose power conditioning where long endurance at elevated temperature is required.

Unique Advantages

• Designed for Switching Environments: The UPJ series is specified for low impedance operation, aligning with the needs of switching power supplies and other high-dynamic-load applications.
• High Ripple Capacity: Rated ripple currents of 1.377 A (120 Hz) and 1.53 A (1 kHz) support effective smoothing across a range of operating frequencies.
