ULD1H6R8MDD

The ULD1H6R8MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s ULD series engineered for long-life operation. It delivers 6.8 µF at 50 V in a compact radial can package and is optimized for applications that require reliable smoothing and energy storage in constrained spaces.

Designed for general-purpose circuits and specifically noted as suited for power supplies for LED lighting, this part combines long-term endurance with RoHS compliance for use in commercial and industrial electronic assemblies.

Key Features

• Long Life Endurance — Rated for 10,000 hours at +105°C, enabling stable performance in high-temperature operating environments.
• Compact Radial Can Package — Small footprint with dimensions L: 1.1 × D: 0.5 cm and a radial lead spacing of 2 mm for space-constrained board layouts.
• Electrical Rating — 6.8 µF capacitance at a 50 V rated voltage with a tolerance of -20% to 20% for predictable charge storage.
• Ripple Handling — Specified ripple current capability of 33.6 mA at 120 Hz and 80 mA at 100 kHz for power-supply ripple smoothing at both low and higher frequencies.
• Wide Operating Temperature — Operates from -40°C to +105°C to support designs exposed to broad temperature ranges.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• LED Lighting Power Supplies — Suited for smoothing and energy storage in LED driver circuits where long life at elevated temperature is required.
• General-Purpose Electronics — Used in compact board-level designs requiring a miniature radial electrolytic capacitor for decoupling or bulk storage.
• Radial-Lead Assemblies — Ideal for through-board radial-lead mounting where a small can package and reliable endurance are needed.

Unique Advantages

• Endurance at Elevated Temperature — 10,000 hours rated life at +105°C provides designers with predictable aging characteristics for long-term deployments.
• Space-Saving Form Factor — 1.1 × 0.5 cm package and 2 mm lead spacing reduce board area without sacrificing rated capacitance and voltage.
• Frequency Versatility — Specified ripple current at both 120 Hz and 100 kHz supports filtering across a range of power-supply switching frequencies.
• Regulatory Compliance — RoHS-compliant construction supports environmental and regulatory requirements for commercial electronics.
• Proven Series Reliability — Part of Nichicon’s ULD long-life series, designed for extended endurance in demanding thermal conditions.
