UHD0J331MED

The UHD0J331MED is a radial-lead aluminum electrolytic capacitor designed for general-purpose electronic applications. It delivers 330 µF capacitance at a 6.3 V rating in a compact φ6.3×11 mm can with 2.5 mm lead spacing.

This part is built for high-ripple, low-impedance use cases—offering specified ripple current performance across low and high frequencies, a wide operating temperature range of −40 °C to 105 °C, and 2,000 hours endurance at 105 °C. Status: End Of Life.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with ±20% tolerance at a rated voltage of 6.3 V.
• Low-impedance, high-ripple performance — Series design emphasizes lower impedance at high frequency. Specified ripple currents: 283.5 mA at 120 Hz and 405 mA at 100 kHz.
• Temperature and endurance — Rated for operation from −40 °C to 105 °C with a life/endurance specification of 2,000 hours at 105 °C.
• Electrical loss and leakage — Tangent of loss angle (tan δ) of 0.22 (20 °C, 120 Hz) and measured leakage current of 20.79 µA.
• Form factor and mounting — Radial lead, polarized aluminum can sized φ6.3×11 mm (L: 1.1 cm × D: 0.63 cm) with 2.5 mm lead spacing (±0.5 mm); available in bulk or bag packing (no terminal forming).
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and filtering in general electronic assemblies where compact radial cans are preferred.
• High-frequency decoupling — Lower impedance at higher frequencies aids decoupling in circuits requiring improved high-frequency performance.
• Environments with elevated ripple — Specified low- and high-frequency ripple current ratings make this capacitor suitable for circuits exposed to significant ripple currents.

Unique Advantages

• Designed for high ripple — Rated ripple currents of 283.5 mA (120 Hz) and 405 mA (100 kHz) support use in ripple-intensive circuits.
• Compact radial package — φ6.3×11 mm can and 2.5 mm lead spacing provide a small-footprint solution for through-hole assemblies.
• Wide operating temperature range — −40 °C to 105 °C rating supports deployment across a broad range of ambient conditions.
• Measurable electrical characteristics — Specified tan δ and leakage current provide predictable loss and leakage behavior for design verification.
• RoHS compliant — Meets RoHS directive requirements for materials compliance.
• Available packaging options — Supplied in bulk or bag packing to suit production or prototyping needs.
