UEP1E471MHD

The UEP1E471MHD is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s UEP series designed for wide temperature operation. It delivers 470 µF at a 25 V rating in a compact radial can (φ12.5×20 mm) and is intended for general‑purpose applications that require stable capacitance and ripple handling across a broad temperature range.

Key value comes from its wide operating range (−55 °C to +105 °C), polarization-tolerant construction, and defined ripple performance across low and high frequencies—making it suitable where reliability and thermal endurance are required.

Key Features

• Bi‑Polar Construction  Designed for applications where polarity can reverse; endurance testing includes polarity inversion cycles to validate performance.
• Rated Capacitance and Voltage  470 µF nominal capacitance with ±20% tolerance at 25 V rated voltage, offering a known bulk energy storage point for power circuits.
• Wide Temperature Range  Operation from −55 °C to +105 °C supports demanding thermal environments and seasonal extremes.
• Ripple Current Capability  Rated ripple current of 380 mA at low frequency (120 Hz) and 570 mA at high frequency (10 kHz), with frequency coefficients available for calculating actual ripple performance.
• Frequency Coefficient Data  For 100–470 µF parts, use frequency multipliers (50 Hz: 0.80, 120 Hz: 1.00, 300 Hz: 1.23, 1 kHz: 1.34, ≥10 kHz: 1.50) to scale ripple current for operating frequency.
• Mechanical and Mounting  Radial lead, can package with case dimensions φ12.5×20 mm, lead spacing 5 mm and lead diameter φ0.6 mm—suitable for through‑hole PCB mounting.
• Reliability and Lifetime  Rated life of 1000 hours at 105 °C; endurance criteria include specified limits for capacitance change, tan δ and leakage after 1000 hours with polarity inversion.
• Compliance and Availability  RoHS‑compliant and listed as mass production; packaged in bulk (no terminal forming) or bag packing for production assembly.

Typical Applications

• Industrial Power Supplies  Used for smoothing and bulk decoupling where wide temperature range and high ripple handling are required.
• AC‑Coupled or Polarity‑Variable Circuits  Bi‑polar construction supports circuits that may experience polarity reversal or AC biasing, improving design flexibility.
• Instrumentation and Control Electronics  Provides stable capacitance and defined endurance for sensors, controllers, and measurement systems operating across extreme temperatures.
• General Purpose Electronic Equipment  A compact radial solution for designers needing reliable bulk capacitance in through‑hole applications.

Unique Advantages

• Polarity Tolerance: Bi‑polar design allows safe operation where polarity can reverse, reducing the need for additional protection components.
• Wide Thermal Range: Operation from −55 °C to +105 °C extends usable environments and reduces risk of thermal‑related failures.
• Frequency‑aware Ripple Rating: Provided ripple current values and frequency coefficients let engineers size capacitors precisely for application frequency, improving thermal and electrical margining.
• Compact Through‑Hole Package: φ12.5×20 mm radial can with 5 mm lead spacing packs significant capacitance into a small PCB footprint for legacy or high‑robustness assemblies.
• Defined Endurance: 1000‑hour lifetime at 105 °C with documented endurance criteria supports reliability planning and lifecycle estimates.
• RoHS Compliance and Production Status: RoHS‑compliant and in mass production for smoother procurement and regulatory alignment.
