UEP1C220MDD

The UEP1C220MDD is a bi-polarized aluminum electrolytic capacitor from Nichicon's UEP series, specified for general-purpose electronic assemblies. It combines a compact radial-can package with a wide operating temperature range and RoHS compliance, addressing designs that require stable capacitance and reliable operation from −55 °C to +105 °C.

Designed for applications that need a compact, leaded capacitor with bi-polar construction, the UEP1C220MDD delivers 22 µF capacitance at a 16 V rating along with defined ripple current and endurance characteristics from the UEP series datasheet.

Key Features

• Capacitance & Voltage — 22 µF rated capacitance at 16 V with ±20% tolerance (120 Hz, 20 °C).
• Bi-Polar Construction — Bi-polarized design suitable for circuits requiring non-polar operation within the specified ratings.
• Wide Temperature Range — Specified operating range from −55 °C to +105 °C for use across broad environmental conditions.
• Endurance — Meet endurance criteria after 1000 hours at 105 °C with polarity inversion every 250 hours, per UEP series specifications.
• Package & Mounting — Radial lead, can-style package with 2.0 mm lead spacing and a compact footprint (L: 1.1 cm × D: 0.5 cm).
• Ripple Current — Rated ripple handling of 40 mA at 120 Hz and 80 mA at 10 kHz (series values provided).
• Leakage Current Specification — Leakage current after 5 minutes at rated voltage ≤ 0.03 C·V (µA), per series datasheet.
• RoHS Compliant — Complies with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Electronics — Suitable for general-purpose circuit assemblies that require a compact bi-polar aluminum electrolytic capacitor within −55 °C to +105 °C operating range.
• Board-Level Radial Mounting — Radial lead package makes the part appropriate for through-hole PCBs and assemblies where a leaded can capacitor is preferred.
• Temperature-Variable Environments — Use in systems that require stable capacitance and defined endurance across wide temperature extremes.

Unique Advantages

• Wide operating temperature capability: The −55 °C to +105 °C rating supports designs exposed to broad thermal ranges without derating outside the specified limits.
• Bi-polarized design for non-polar use: Enables applications that require polarity-independent capacitance within the rated voltage and endurance conditions.
• Compact radial can footprint: The small L and D dimensions and 2.0 mm lead spacing provide space-efficient through-hole mounting for dense PCB layouts.
• Defined ripple performance: Specified ripple current values at 120 Hz and 10 kHz give clear guidance for power-handling in low- and high-frequency environments.
• 1000‑hour endurance at 105 °C: Endurance characterization with polarity inversion provides predictable long-term behavior under elevated temperature stress.
• RoHS compliance: Meets current RoHS requirements for reduced hazardous substances in electronic assemblies.
