UEP1E102MHD

The UEP1E102MHD from Nichicon is a bi-polar aluminum electrolytic capacitor in the UEP series, designed for general-purpose electronic applications. It provides 1 mF capacitance at a 25 V rating, packaged in a radial can with radial lead mounting for through-hole PCB assemblies.

Engineered for operation across a wide temperature range (−55°C to +105°C) and compliant with RoHS, this capacitor suits designs that require bipolar capacitance, stable ripple handling, and durable high-temperature endurance.

Key Features

• Bi-Polar Construction 
  Provides bipolar polarization for AC or polarity-reversing applications where a non-polarized electrolytic solution is required.
• Capacitance & Voltage 
  1 mF capacitance with a 25 V rated voltage and ±20% tolerance for predictable charge storage in general-purpose circuits.
• Wide Temperature Range 
  Specified to operate from −55°C to +105°C, supporting demanding thermal environments.
• High-Temperature Endurance 
  Rated for 1000 hours at 105°C with periodic polarity inversion as defined by the series endurance specification.
• Ripple Current Performance 
  Rated ripple currents include 670 mA at 120 Hz and 770.5 mA at 10 kHz, with frequency coefficients provided in the series documentation.
• Radial Lead Package 
  Radial lead, radial can package with 7.5 mm lead spacing for straightforward through-hole PCB mounting and mechanical stability.
• RoHS Compliant 
  Manufactured in compliance with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Electronics 
  Used where a bi-polar aluminum electrolytic capacitor is required for general circuit needs across a wide temperature range.
• Through-Hole PCB Assemblies 
  Radial lead and can package suit through-hole boards and assemblies that use radial components for power or signal circuits.
• Environments Requiring Wide Temperature Operation 
  Applicable in designs that need reliable capacitance from −55°C up to +105°C.

Unique Advantages

• Bi-polar capability: Enables use in AC-coupled or polarity-reversing circuits without polarity constraints.
• Wide operating window: −55°C to +105°C rating provides design latitude for applications exposed to broad temperature swings.
• Documented high-temperature endurance: 1000 hours at 105°C endurance characterization supports longevity planning for elevated-temperature deployments.
• Measurable ripple handling: Specified ripple currents at 120 Hz and 10 kHz make it easier to validate thermal and ripple performance in power circuits.
• Board-friendly radial format: 7.5 mm lead spacing and radial lead construction simplify PCB layout and mechanical mounting in through-hole assemblies.
• Regulatory compliance: RoHS compliance aligns with environmental and product stewardship requirements.
