UEP1C330MDD

The UEP1C330MDD is a bi-polarized aluminum electrolytic capacitor from Nichicon’s UEP series designed for wide temperature operation. It delivers a rated capacitance of 330µF at 16V in a compact radial can (φ10×16mm) with 5.0mm lead spacing, intended for general-purpose through-hole applications that require bipolar operation over a broad temperature range.

Key electrical and reliability characteristics include a wide operating temperature range of −55°C to +105°C and an endurance specification of 1000 hours at 105°C. Status: End Of Life.

Key Features

• Bi-Polarized Construction Enables operation with polarity inversion, suitable for AC-coupled circuits and bipolar signal paths.
• Rated Voltage & Capacitance 16 V rated voltage with 330µF nominal capacitance and ±20% tolerance (measured at 120Hz, 20°C).
• Wide Temperature Range Specified for −55°C to +105°C operation, supporting designs exposed to extended thermal environments.
• Endurance and Reliability Life rating of 1000 hours at 105°C with polarity inversion every 250 hours (endurance measured per datasheet conditions).
• Leakage Current Listed leakage current: 15.84 µA; datasheet leakage specification: not more than 0.03CV (µA) after 5 minutes’ application of rated voltage at 20°C.
• Ripple Current Performance Ripple current specification examples: 49 mA at 120 Hz (low frequency) and 98 mA at 10 kHz (high frequency) for the part’s capacitance class.
• Package & Mounting Radial lead, can-style package (φ10×16mm) with 5.0mm lead spacing supplied in bulk (no terminal forming) or bag packing.
• RoHS Compliance Compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• AC-coupling and Signal Conditioning Use in circuits requiring bipolar capacitors for AC coupling, filtering, or signal path stabilization where polarity reversal can occur.
• Power-Supply Filtering Through-hole radial mounting makes it suitable for local decoupling and smoothing in low-voltage power rails in industrial and instrumentation equipment.
• Temperature-Variable Environments Systems operating across wide ambient ranges that require stable capacitance and endurance up to 105°C.

Unique Advantages

• Bipolar operation: Designed for circuits that experience polarity reversal without the need for series balancing or special circuit arrangements.
• Wide thermal capability: Rated from −55°C to +105°C to support demanding environmental conditions and extended temperature excursions.
• Compact radial can: φ10×16mm package provides a space-efficient solution for through-hole PCB layouts where board space is limited.
• Defined endurance: 1000 hours at 105°C with polarity inversion cycle information offers predictable aging behavior for lifecycle planning.
• Measurable leakage spec: Leakage current provided as both a part-specific value (15.84 µA) and the datasheet limit (0.03CV), aiding in analytical design margin calculations.
• RoHS compliant: Meets current restricted substance requirements for environmentally regulated designs.
