UPA1C222MHD

The UPA1C222MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPA series, engineered for miniature, high-reliability power applications. It is a polarized, radial can-type capacitor specified for general-purpose use and explicitly designed for switching power supplies.

This part delivers low impedance and high ripple-current capability in a compact package, with RoHS compliance and durability up to 105 °C.

Key Features

• Capacitance and Voltage: 2.2 mF nominal capacitance rated at 16 V, with a tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Low Impedance: Rated impedance of 58 mΩ, providing improved AC performance for power filtering and decoupling.
• High Ripple Current Capability: Ripple current specified at 1.607 A (120 Hz) and 1.89 A (10 kHz), supporting demanding switching environments.
• Compact Radial Can Package: Radial, can-style casing with 5 mm lead spacing and compact dimensions (L: 2 × D: 1.25 cm) for space-constrained PCB layouts.
• Wide Temperature Range: Rated for operation from −55 °C to +105 °C, suitable for elevated-temperature power stages.
• Endurance: Lifetime specified as 5000 hours at 105 °C under rated conditions (series endurance characteristics apply).
• Leakage Current: After 1 minute at 20 °C, leakage current is specified as not more than 0.03CV or 4 µA (whichever is greater), per series specifications.
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Provides low impedance and high ripple-current handling where compact smoothing and decoupling are required.
• General-Purpose Power Filtering — Suitable for bulk decoupling and smoothing in a variety of electronic power circuits.
• Radial Through-Hole Power Assemblies — Designed for radial lead mounting in through-hole boards and assemblies where a can-style electrolytic is preferred.

Unique Advantages

• Low AC Losses: 58 mΩ impedance reduces voltage ripple and heat generation in power stages.
• High Ripple Capacity: Specified ripple currents at both low (120 Hz) and high (10 kHz) frequencies support switching regulator loads.
• Compact Footprint: Small case dimensions (L: 2 × D: 1.25 cm) enable denser PCB layouts without sacrificing performance.
• Wide Operating Range: −55 °C to +105 °C rating permits use in elevated-temperature environments common to power electronics.
• Proven Endurance: 5000-hour life at 105 °C under rated conditions provides predictable, long-term behavior in sustained thermal stress.
• Regulatory Compliance: RoHS conformity supports environmentally driven designs and supply-chain requirements.
