ULD2G6R8MPD

The ULD2G6R8MPD is a polarized aluminum electrolytic capacitor in a radial‑lead can, rated 6.8 µF at 400 V. It belongs to Nichicon’s ULD series of miniature, long‑life capacitors and is intended for general purpose power applications, including power supplies for LED lighting.

Designed for long operational life and compact installation, this part delivers 20,000 hours endurance at 105°C, a wide operating temperature range of -40°C to 105°C, and measurable ripple‑current capability for both low and high frequency environments.

Key Features

• Capacitance & Voltage — 6.8 µF nominal capacitance rated at 400 V DC, suitable for high‑voltage power circuits.
• Long Life Endurance — Rated for 20,000 hours at 105°C under the ULD series life specification, supporting extended service intervals.
• Temperature Range — Operating from -40°C to 105°C, enabling use across a broad thermal envelope.
• Measured Dissipation Factor — tanδ = 0.24 measured at 20°C, 120 Hz, 400 V, providing a quantifiable loss parameter for design calculations.
• Ripple Current Capability — Low‑frequency ripple current 85 mA at 120 Hz and high‑frequency ripple current 161.5 mA at 100 kHz, specified for both mains‑frequency and switching environments.
• Leakage Current — Specified leakage current 208.8 µA, allowing predictable bias‑leak behavior in DC applications.
• Compact Radial Package — φ10 × 16L can with 5.0 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assembly; offered in bulk/no terminal forming or bag packing.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C.
• RoHS Compliant — Conforms to RoHS directive as indicated for the ULD series.

Typical Applications

• LED lighting power supplies — Suited to energy storage and smoothing in LED driver circuits that require high voltage rating and extended life.
• General purpose power electronics — Use where a compact, high‑voltage polarized capacitor with predictable leakage and ripple characteristics is needed.
• High‑voltage DC circuits — Applicable for decoupling and buffering in compact through‑hole designs operating up to 400 V.

Unique Advantages

• Extended operational life — 20,000 hours at 105°C reduces replacement frequency and supports long‑life product designs.
