UEP2A010MDD

The UEP2A010MDD from Nichicon is a bi‑polarized aluminum electrolytic capacitor in the UEP series, designed for general‑purpose electronic applications requiring AC or polarity‑reversing operation. It delivers 1 µF capacitance at a 100 V rating in a compact radial‑lead can, combining wide temperature tolerance and defined endurance for reliable operation in demanding environments.

Key technical strengths include bi‑polar operation, a wide operating temperature range of -55°C to +105°C, RoHS compliance, and a specified 1000‑hour endurance at 105°C with periodic polarity inversion—attributes that support stable performance in circuits exposed to thermal stress and polarity changes.

Key Features

• Bi‑Polarized Operation Designed for use where polarity may reverse; endurance testing includes polarity inversion every 250 hours during 1000 hours at 105°C.
• Electrical Rating 1 µF capacitance with a 100 V rated voltage and ±20% tolerance, suitable where higher voltage capability is required in a small electrolytic package.
• Wide Temperature Range Specified to operate from -55°C to +105°C for applications that see extreme low and high ambient temperatures.
• Package and Mounting Radial lead, can‑style package with 2 mm lead spacing for through‑hole assembly and straightforward PCB placement.
• Endurance and Reliability Lifetime: 1000 hours at 105°C under rated voltage with polarity inversion; leakage current specified as not more than 0.03CV (µA) after 5 minutes at 20°C per the series specification.
• Ripple Current Capability Specified ripple current values: 15 mA at 120 Hz and 30 mA at 10 kHz, with frequency coefficients defined by the UEP series.
• Environmental Compliance RoHS compliant, meeting directive requirements for restricted substances.

Typical Applications

• AC Coupling and Signal Circuits Use where polarity can reverse—ideal for coupling and decoupling stages in amplifiers or signal path networks that require a bipolar capacitor.
• Instrumentation and Test Equipment Provides stable capacitance across a wide temperature range for precision analog circuitry and measurement systems.
• Power Supply Filtering Suitable for decoupling and smoothing in low‑to‑moderate ripple power rails where a 100 V rating and defined ripple current are required.
• General‑Purpose Electronic Modules A compact radial lead solution for boards and assemblies requiring robust, polarized‑reversible electrolytic capacitance.

Unique Advantages

• Bi‑polar capability for polarity‑reversing designs: Enables use in circuits that encounter AC or inverted polarity without requiring separate polarity protection components.
• Wide operating temperature: -55°C to +105°C rating supports applications exposed to broad thermal ranges without derating the capacitor selection.
• High voltage margin: 100 V rated voltage expands applicability to higher‑voltage circuits while keeping capacitance compact.
• Verified endurance with polarity inversion: 1000 hours at 105°C with periodic polarity inversion aligns with long‑term stability requirements for thermal stress conditions.
• Low leakage specification: Leakage current limited to 0.03CV (µA) after initial application of rated voltage at 20°C, helping maintain circuit bias and minimizing drift.
• RoHS compliant: Meets environmental regulatory requirements for restricted substances.
