UEP1C470MED

The UEP1C470MED is a bi‑polarized aluminum electrolytic capacitor from Nichicon’s UEP series designed for general‑purpose electronic applications. It offers a wide operating temperature range of −55°C to +105°C and a radial‑lead, can‑style package for through‑hole mounting.

With a rated voltage of 16 V and rated capacitance of 470 µF (±20% at 120 Hz, 20°C), this capacitor is specified for applications that require bipolar performance, elevated ripple handling, and 1000 hours of endurance at 105°C.

Key Features

• Bi‑Polarized Construction Enables operation with polarity inversion, supporting circuits where voltage polarity can reverse.
• Wide Temperature Range Rated for −55°C to +105°C for use across extended environmental conditions.
• Voltage & Capacitance Rated voltage 16 V and rated capacitance 470 µF with a tolerance of ±20% (120 Hz, 20°C).
• High Ripple Capability Rated ripple current: 345 mArms at 105°C / 120 Hz; frequency coefficients for the 100–470 µF group allow higher ripple at elevated frequencies (e.g., 1.00 at 120 Hz, 1.50 at 10 kHz).
• Low Loss (tan δ) Tangent of loss angle (tan δ) max. 0.20 at the 16 V rating (measured at 120 Hz, 20°C).
• Low Leakage Current Measured leakage current: 225.6 µA at 20°C after 5 minutes; series specification limits leakage to not more than 0.03 C·V (µA) after 5 minutes under rated voltage.
• Compact Radial Can Package Case size φ10×20 mm with 5.0 mm lead spacing and radial lead mounting for robust through‑hole assembly.
• Endurance Specified endurance of 1000 hours at 105°C with polarity inversion every 250 hours; for 6.3–16 V parts (including 16 V), capacitance change is within ±25% after the test.
• RoHS Compliant Conforms to RoHS directive requirements.

Typical Applications

• General‑Purpose Electronics — Suited for circuits that require a bipolar capacitor with 16 V / 470 µF of capacitance and operation across −55°C to +105°C.
• Bipolar Signal Paths — Bi‑polarized construction supports use in circuits where voltage polarity may invert or where AC coupling is required.
• Power Filtering and Decoupling — Rated ripple current of 345 mArms at 105°C/120 Hz and frequency coefficients for the 100–470 µF group make it appropriate for smoothing and decoupling duties across a range of frequencies.

Unique Advantages

• Polarity‑Flexible Design: Bi‑polarized construction eliminates the need to orient polarity in circuits that experience inversion, simplifying layout and assembly.
• Wide Temperature Capability: −55°C to +105°C rating ensures stable performance across harsh thermal conditions.
• High Ripple Endurance: The 345 mArms ripple rating at elevated temperature combined with published frequency coefficients helps designers manage AC stress at both low and high frequencies.
• Proven Endurance: 1000 hours at 105°C with polarity inversion demonstrates durability for long‑term applications.
• Compact Through‑Hole Form Factor: φ10×20 mm radial can with 5.0 mm lead spacing provides a space‑efficient solution for PCB designs that require through‑hole components.
• Regulatory Compliance: RoHS compliance supports usage in designs targeting restricted substances requirements.
