UHV1E331MPD

The UHV1E331MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHV series, designed for high ripple and low-impedance performance in a compact can. It provides 330 µF capacitance at a 25 V rating with a small φ8 × 11.5 mm case and 3.5 mm lead spacing.

Engineered for general-purpose power applications, the part combines a low impedance (181 mΩ) and substantial ripple handling with long-term endurance (6,000 hours at 105°C), making it suitable where compact size, thermal reliability, and effective ripple suppression are required.

Key Features

• Capacitance & Tolerance — 330 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 25 V DC rating for a wide range of low-voltage power rails.
• Low Impedance — Specified impedance of 181 mΩ supports improved ripple and transient performance.
• High Ripple Current Capability — Rated ripple currents of 495 mA (120 Hz) and 990 mA (100 kHz) for effective AC ripple handling across frequency ranges.
• Loss Angle (tan δ) — tan δ = 0.13 (measured at 20°C, 120 Hz), enabling predictable dissipation characteristics.
• Leakage Current — Typical leakage current 82.5 µA after 2 minutes at rated voltage (20°C), consistent with the series specification I ≤ 0.01CV.
• Temperature & Endurance — Operating range −40°C to +105°C with endurance of 6,000 hours at 105°C under rated bias and ripple conditions.
• Compact Radial Can — Case size φ8 × 11.5 mm with 3.5 mm lead spacing and radial lead mounting for through-hole assemblies.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible inventory handling.
• RoHS Compliant — Meets RoHS requirements as stated in product data.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple suppression on low-voltage DC rails where reliable smoothing is required.
• Compact power modules — Small φ8 × 11.5 mm can and radial leads fit space-constrained through-hole power assemblies.
• High-frequency decoupling — Lower impedance and frequency-capable ripple handling support decoupling at higher switching frequencies.

Unique Advantages

• High ripple-handling in a small package: Rated ripple currents up to 990 mA at 100 kHz deliver effective AC tolerance without a large case footprint.
• Predictable dissipation: Measured tan δ (0.13 at 20°C, 120 Hz) provides reliable loss characteristics for thermal planning.
• Endurance for thermal stress: 6,000-hour life at 105°C under rated conditions supports sustained operation in elevated-temperature environments.
• Compact radial mounting: φ8 × 11.5 mm can and 3.5 mm lead spacing simplify placement in through-hole designs while conserving board area.
• Low steady-state leakage: Leakage current consistent with 0.01CV (≈82.5 µA) helps minimize quiescent losses on power rails.
• RoHS compliance: Meets RoHS directive requirements for regulatory alignment in assembly processes.
