UEP1H470MPD

The UEP1H470MPD is a bi-polarized aluminum electrolytic capacitor in a radial can package designed for general-purpose electronic applications. Its construction supports bi-polar operation and a wide operating temperature range, making it suitable for circuits that require stable capacitance over extreme temperatures.

Key value comes from its combination of compact radial-lead packaging, RoHS compliance, and verified endurance performance at elevated temperature conditions.

Key Features

• Capacitance & Voltage — 47 µF rated capacitance with a 50 V rated voltage and ±20% tolerance (120 Hz, 20°C), providing defined energy storage for a range of general-purpose circuits.
• Bi-Polarized Design — Bi-polar polarization allows use in AC-coupling and circuits where polarity reversals are expected.
• Wide Temperature Range — Rated for operation from −55°C to +105°C for applications exposed to broad environmental conditions.
• Durability & Endurance — Specified endurance of 1000 hours at 105°C with the polarity inverted every 250 hours, meeting the series endurance criteria for capacitance, tan δ and leakage current.
• Ripple Current Capability — Rated ripple current of 105 mA at 120 Hz and 210 mA at 10 kHz, with frequency-coefficient behavior consistent with 10–47 µF capacitor characteristics.
• Package & Mounting — Radial lead, can-style package with 5 mm lead spacing and compact dimensions (L: 1.25 cm × D: 1.00 cm) for through-hole assemblies.
• Regulatory Compliance — RoHS compliant, meeting the applicable directive requirements.

Typical Applications

• General-purpose electronic circuits — Energy storage and decoupling in a variety of assemblies where a bi-polarized electrolytic is required.
• AC coupling and signal circuits — Use in circuits that experience polarity reversals or require non-polarized capacitor behavior.
• Power filtering in industrial electronics — Local smoothing and ripple suppression where elevated temperatures and sustained ripple currents occur.

Unique Advantages

• Bi-polar compatibility: Eliminates polarity constraints for AC or polarity-reversing circuits, simplifying design choices where non-polar operation is needed.
• Extended temperature capability: Operation from −55°C to +105°C enables deployment in environments with wide thermal swings without sacrificing rated performance.
• Validated endurance: 1000-hour life at 105°C with polarity inversion provides documented reliability data for thermal-stress applications.
• High-frequency ripple handling: Measured ripple current ratings up to 210 mA at 10 kHz support applications with significant high-frequency content.
• Compact radial can package: Small L × D footprint and 5 mm lead spacing simplify placement in through-hole designs while maintaining required capacitance.
• RoHS compliance: Conforms to current directive requirements for reduced hazardous substances.
