UEP1C331MPD

The UEP1C331MPD is a bi‑polarized aluminum electrolytic capacitor designed for general‑purpose electronic circuits that require reversible polarity and wide temperature capability. It delivers 330 µF at a 16 V rating in a compact radial can (φ10×16 mm) with 5 mm lead spacing.

Engineered for stability across a broad operating range (−55 °C to +105 °C) and endurance under elevated temperature stress, this part is suited where compact size, reliable ripple handling, and tolerance to polarity inversion are required.

Key Features

• Bi‑Polarized Construction — Designed for applications where polarity can reverse; endurance testing includes polarity inversion during high‑temperature life tests.
• Wide Temperature Range — Rated for operation from −55 °C to +105 °C, supporting circuits exposed to extreme ambient conditions.
• Rated Electricals — 330 µF capacitance at 16 V with ±20% tolerance and a specified leakage current of 158.4 µA.
• Ripple Handling — Rated ripple current of 265 mA at 105 °C / 120 Hz and 397.5 mA at 10 kHz, enabling effective smoothing and decoupling in AC‑stressed applications.
• Compact Radial Package — φ10×16 mm aluminum can with radial leads and 5 mm lead spacing for through‑hole mounting and dense board layouts.
• Endurance and Shelf Life — Life rating of 1000 hours at 105 °C with specified recovery characteristics after voltage treatment, demonstrating stability over time.
• RoHS Compliant — Manufactured to meet RoHS directives.

Typical Applications

• General‑purpose electronic assemblies — Provides bulk capacitance and polarity‑tolerant filtering where a compact radial electrolytic is required.
• AC‑coupled and polarity‑reversing circuits — Bi‑polarized design supports circuits that experience polarity inversion or alternating signals.
• Power supply decoupling and smoothing — Capacitance, tolerance, and rated ripple current make it suitable for local energy storage and ripple suppression in low‑voltage supplies.
• Temperature‑challenged environments — Wide −55 °C to +105 °C rating fits designs that must operate reliably across large temperature swings.

Unique Advantages

• Polarity flexibility: Bi‑polarized design enables use in circuits with reversed or alternating polarity without requiring orientation changes.
• Wide thermal resilience: −55 °C to +105 °C operating range supports deployment in harsh thermal environments.
• Measured ripple capability: Rated ripple currents (265 mA at 120 Hz, 397.5 mA at 10 kHz) provide quantifiable performance for filtering and decoupling tasks.
• Compact footprint: φ10×16 mm radial can and 5 mm lead spacing balance capacitance with a small PCB footprint for space‑constrained designs.
• Proven endurance: 1000 hours at 105 °C (with polarity inversion in endurance test) demonstrates long‑term stability under stress.
• Regulatory compliance: RoHS compliant construction supports environmentally conscious product development.
