UEP1C221MPD

The UEP1C221MPD is a bi-polarized aluminum electrolytic capacitor from Nichicon’s UEP series, offering 220µF capacitance at a 16V rating in a compact radial-can package. Engineered for wide-temperature operation and general-purpose use, it provides polarized-capacitor performance without fixed polarity constraints.

Key design attributes—bi‑polar construction, a −55°C to +105°C operating range, measurable ripple-current capability, and a compact φ10×12.5mm can with 5mm lead spacing—make this part suitable for circuits that require stable capacitance across broad thermal conditions and alternating polarity environments.

Key Features

• Bi‑Polar Construction Enables operation with alternating polarity where a non-polar solution is required; simplifies circuit design that encounters polarity reversal.
• Electrical Rating 220µF nominal capacitance at 16V with ±20% tolerance, providing predictable energy storage for low-voltage applications.
• Wide Temperature Range Rated for −55°C to +105°C operation, supporting designs that must perform across extended ambient conditions.
• Ripple Current Capability Rated ripple current of 195mA at 120Hz and 292.5mA at 10kHz, allowing reliable AC and high‑frequency ripple handling within specified limits.
• Low Leakage Specified leakage current of 105.6µA, supporting stable long-term performance after voltage application.
• Compact Radial Package φ10×12.5mm can, radial lead mounting with 5mm lead spacing, supplied in bulk/bag packing; suitable for through‑hole layouts and manual or automated insertion.
• Endurance Lifetime specified as 1000 hours at 105°C (with polarity inversion per series endurance conditions), supporting durability in elevated-temperature environments.
• RoHS Compliant Conforms to RoHS requirements as stated in product data.

Typical Applications

• General-purpose electronic circuits For designs that require a 220µF, 16V bi‑polarized capacitor with broad temperature tolerance and radial through-hole mounting.
• AC coupling and polarity‑reversing circuits Bi‑polarized construction supports circuits where polarity may reverse, leveraging the capacitor’s alternating‑polarity capability.
• Low‑voltage power filtering Provides bulk capacitance and ripple handling at 16V systems where stable capacitance and moderate ripple current ratings are required.

Unique Advantages

• Alternating‑polarity capability: Bi‑polar construction removes polarity constraints encountered in many AC or bidirectional circuits.
• Broad thermal endurance: −55°C to +105°C rating and 1000 hours endurance at 105°C support reliable operation in demanding temperature environments.
• Measured ripple performance: Clear ripple‑current specifications at 120Hz and 10kHz let designers account for low‑ and high‑frequency ripple in system thermal budgets.
• Compact radial form factor: φ10×12.5mm can and 5mm lead spacing minimize board space while keeping through‑hole mounting simplicity.
• Low leakage current: Specified leakage of 105.6µA helps maintain circuit stability over time after voltage application.
• RoHS compliance: Meets environmental compliance expectations for modern electronics supply chains.
