UEP1H330MPD

The UEP1H330MPD is an aluminum electrolytic capacitor in a radial-can package, configured as a bi-polarized device. It provides 33 µF capacitance at a 50 V rating with radial lead mounting and a compact footprint for general-purpose electronic designs.

Designed for wide temperature operation and extended endurance, this Nichicon UEP-series capacitor operates from −55 °C to +105 °C, is RoHS compliant, and delivers specified ripple current performance for both low and high frequency environments.

Key Features

• Electrical — 33 µF, 50 V Nominal capacitance of 33 µF with a 50 V rated voltage and ±20% tolerance for general-purpose decoupling and coupling applications.
• Bi-Polar Design Bi-polarized construction allows operation without polarity constraints, suitable for AC-coupled or polarity-reversing circuits.
• Wide Temperature Range Specified for operation from −55 °C to +105 °C to support designs that require broad environmental margin.
• Reliability and Endurance Endurance specified as 1000 hours at 105 °C with polarity inversion every 250 hours, meeting the UEP series endurance criteria when returned to 20 °C.
• Ripple Current Performance Measured ripple current capabilities include 77 mA at 120 Hz and 154 mA at 10 kHz, with series frequency coefficients available in the datasheet.
• Compact Radial Package Radial lead, can-style package with 3.5 mm lead spacing and physical dimensions of approximately L: 1.15 × D: 0.8 cm for space-conscious PCB layouts.
• Environmental Compliance RoHS compliant per the series specification.

Typical Applications

• Analog and Audio Circuits — Bi-polar construction enables AC coupling and signal path applications where polarity-independent capacitance is required.
• General-Purpose Power and Filtering — Used for smoothing and ripple suppression in circuits that benefit from a compact radial electrolytic solution.
• Industrial Electronics — Wide −55 °C to +105 °C operating range supports equipment exposed to broad temperature variations.
• PCB Designs with Tight Footprints — Compact dimensions and 3.5 mm lead spacing make the part suitable for densely populated boards requiring through-hole radial components.

Unique Advantages

• Polarity Flexibility: Bi-polarized construction removes polarity constraints, simplifying placement in AC-coupled and polarity-reversing circuits.
• Wide Thermal Tolerance: Rated from −55 °C to +105 °C, enabling use across a broad range of environmental conditions without derating the core capacitance specification.
• Documented Endurance: 1000-hour endurance at 105 °C with polarity inversion provides a verifiable reliability baseline for long-term designs.
• Frequency-Aware Ripple Ratings: Specified ripple current values at 120 Hz and 10 kHz help match the capacitor to both low- and high-frequency power and signal environments.
• Compact Radial Form Factor: Small can footprint and standard radial lead spacing support simple through-hole assembly while conserving PCB area.
• Regulatory Compliance: RoHS-compliant construction for projects requiring restricted-substance conformance.
