UEP1A222MHD

The UEP1A222MHD from Nichicon is a bi-polarized aluminum electrolytic capacitor in the UEP series designed for wide temperature operation. It delivers 2200µF capacitance at a 10V rating with a compact radial-can package (φ16×25L) and 7.5mm lead spacing.

Targeted at general-purpose electronic designs, this capacitor combines broad operating temperature range, defined endurance, and measurable ripple handling to support decoupling, smoothing and AC-coupled applications where polarity may reverse and environmental conditions vary.

Key Features

• Bi-Polarized Construction Supports applications with AC or polarity-reversal conditions by design.
• Rated Capacitance & Voltage 2200µF nominal capacitance with a 10V rated voltage and ±20% tolerance for bulk energy storage and decoupling in low-voltage systems.
• Wide Temperature Range Operates from −55°C to +105°C, enabling use across broad environmental conditions.
• Endurance Specified life of 1000 hours at 105°C with polarity inversion every 250 hours, providing predictable long-term performance under elevated temperature stress.
• Loss & Leakage Specified tanδ of 0.26 and leakage current of 660µA, useful for estimating dissipation and standby current in sensitive designs.
• Ripple Current Capability Rated ripple currents of 910 mA at 120 Hz and 1.046 A at 10 kHz, allowing effective smoothing of low- and high-frequency ripple components.
• Package & Mounting Radial lead, can-style package (φ16×25L) with 7.5mm lead spacing; available in bulk (no terminal forming) and bag packing for production or prototype workflows.
• Compliance & Availability RoHS compliant and listed as mass production status for supply continuity.

Typical Applications

• Industrial Control Boards Wide −55°C to +105°C rating and bi-polarized construction suit control electronics exposed to varying temperatures and polarity conditions.
• Power Supply Filtering 2200µF at 10V with defined ripple current ratings provides bulk smoothing and decoupling on low-voltage rails.
• Signal and AC Coupling Bi-polarized design enables use in AC-coupled circuits and applications where polarity can reverse without a dedicated biasing scheme.
• General-Purpose Electronics Radial lead package and standard sizing (φ16×25L) make it suitable for a wide range of PCB designs requiring robust electrolytic capacitance.

Unique Advantages

• Polarity-flexible design: Bi-polarized construction removes the need for strict DC polarity alignment in applicable circuits.
• Wide operational temperature: −55°C to +105°C rating supports deployment across harsh thermal environments without derating the component choice.
• Predictable endurance: 1000-hour specification at 105°C with polarity inversion provides defined lifecycle planning for thermal-stressed applications.
• Measurable ripple handling: Published ripple current values at 120 Hz and 10 kHz allow designers to size capacitors for both low- and high-frequency ripple scenarios.
• Compact radial can package: φ16×25L dimensions with 7.5mm lead spacing fit common PCB layouts while offering substantial capacitance for the footprint.
• RoHS compliant and production-ready: Environmentally compliant with mass-production availability for design continuity and procurement.
