UEP2A220MPD

The UEP2A220MPD is a bi-polarized aluminum electrolytic capacitor in a radial-can package designed for general-purpose electronics. Its bi-polar construction and wide operating temperature range make it suitable for circuits that require non-polar operation across harsh temperature conditions.

With a 22 µF capacitance at a 100 V rating, compact radial lead form factor, and RoHS compliance, this component targets applications that need reliable bulk or decoupling capacitance in through-hole assemblies.

Key Features

• Capacitance & Voltage — 22 µF capacitance rated at 100 V, with a tolerance of ±20% (measured at 120 Hz, 20 °C).
• Bi-Polarized Design — Bi-polar construction supports non-polar operation and alternating polarity applications consistent with the UEP series description.
• Wide Temperature Range — Specified operating range from −55 °C to +105 °C for use in demanding thermal environments.
• Endurance — Rated for 1000 hours at 105 °C with polarity inversion every 250 hours; designed to meet the series endurance criteria for capacitance, tan δ and leakage after recovery to 20 °C.
• Leakage and Loss Characteristics — Series leakage: after 5 minutes at rated voltage and 20 °C, leakage current is specified as not more than 0.03CV (µA); tangent of loss angle (tan δ) for 100 V units is specified with a maximum of 0.10.
• Ripple Current Capability — Rated ripple current: 97 mA at 120 Hz and 194 mA at 10 kHz, supporting frequency-dependent ripple handling for both low- and high-frequency applications.
• Package & Mechanical — Radial lead, can-style package with lead spacing of 5 mm and compact dimensions (L: 1.6 cm × D: 1.0 cm), suitable for through-hole PCB assemblies.
• Compliance — RoHS compliant, meeting the stated environmental requirement.

Typical Applications

• Power Supply Filtering — Bulk and decoupling capacitance for general-purpose power supply rails where 100 V rating and wide temperature performance are required.
• Signal and Coupling Circuits — Bi-polarized construction enables use in AC-coupling and circuits where polarity may reverse during operation.
• Industrial Controls — Through-hole radial package and extended temperature range support robust assemblies in industrial electronics and control boards.

Unique Advantages

• Non‑polar Operation: Bi-polarized construction permits use in circuits with alternating or reversed polarity, reducing constraints on circuit topology.
• Wide Thermal Capability: Rated from −55 °C to +105 °C, enabling reliable performance across demanding temperature extremes.
• High Voltage Headroom: 100 V rating provides margin for higher-voltage rails within general-purpose designs.
• Verified Endurance: Specified 1000-hour endurance at 105 °C with polarity inversion cycles, supporting long-term reliability evaluations.
• Frequency-aware Ripple Handling: Documented ripple current values at both 120 Hz and 10 kHz help engineers size components for mixed-frequency loads.
• RoHS Compliant: Meets environmental requirements for lead-free assemblies.
