UUN2A220MNQ1MS

The UUN2A220MNQ1MS is a bi-polarized aluminum electrolytic chip capacitor from Nichicon's UUN series, offering 22 µF capacitance at a 100 V rating in a compact surface-mount can package. It is designed for surface mounting on high-density PC boards and is compatible with automatic mounting machines fed with carrier tape.

Engineered for general-purpose electronic assemblies, the part supports operation across a wide temperature range of −55°C to +105°C and meets RoHS (2011/65/EU, (EU)2015/863) requirements.

Key Features

• Core Electrical — 22 µF rated capacitance with 100 V rated voltage and ±20% tolerance for predictable electrical behavior.
• Bi-Polar Construction — Bi-polarized design suitable for AC or polarity-inverting applications across the specified temperature range.
• Thermal & Reliability — Rated for operation from −55°C to +105°C and specified endurance of 2000 hours at 105°C with polarity inversion every 250 hours.
• Ripple Performance — Ripple current capability specified as 100 mA at 120 Hz and 200 mA at 10 kHz to support AC components of the circuit.
• Package & Mounting — Surface-mount radial can (SMD) package sized L: 1.35 × D: 1.25 cm with recommended land size L: 1.28 × W: 1.28 cm; compatible with tape-fed automated placement.
• Environmental Compliance — Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose PCB assemblies — Surface-mount bi-polarized capacitor for densely routed circuit boards where a compact SMD can is required.
• Environments with wide temperature variation — Suited to designs requiring reliable capacitance performance from −55°C to +105°C.
• Automated production — Designed for use with carrier-tape-fed automatic mounting machines for high-volume assembly.

Unique Advantages

• Wide temperature tolerance: Operation from −55°C to +105°C enables use in applications exposed to broad ambient conditions.
• Bi-polar design reduces orientation constraints: Eliminates polarity concerns in AC or polarity-reversing circuits.
• Compact SMD can for high-density boards: Small L × D footprint and defined land pattern simplify layout on crowded PCBs.
• Defined ripple current ratings: Specified ripple handling at 120 Hz and 10 kHz helps designers size components for expected AC stress.
• Endurance specification: 2000 hours at 105°C with polarity inversion provides a measurable reliability baseline for thermal stress conditions.
• RoHS compliant: Meets current RoHS directives for regulatory and environmental alignment.
