ULD2G010MED

The ULD2G010MED is a radial-lead aluminum electrolytic capacitor from Nichicon’s ULD series. It delivers a 1 µF capacitance at a 400 V rating in a compact φ6.3×11 mm can, designed for general-purpose high-voltage circuitry.

Engineered for long operating life and stable performance across a wide temperature range, this part is suitable for applications such as power supplies and LED driver circuits where compact size, high voltage capability, and reliable ripple performance are required.

Key Features

• Capacitance & Voltage — 1 µF capacitance with a 400 V rated voltage and tolerance of -20% to +20% for high-voltage DC applications.
• Low-loss Performance — Tangent of loss angle (tanδ) 0.24 measured at 20°C, 120 Hz, helping to minimize dissipation in AC-biased conditions.
• Ripple and Leakage — Low-frequency ripple current 24 mA at 120 Hz, high-frequency ripple current 48 mA at 100 kHz, and leakage current specified at 80 µA for predictable power-system behavior.
• Thermal and Endurance — Rated for -40°C to +105°C operation with an endurance life of 12,000 hours at 105°C.
• Compact Radial Package — φ6.3×11 mm can with 2.5 mm lead spacing (±0.5 mm tolerance) and radial-lead mounting for through-hole assembly.
• Packaging & Compliance — Available in Bulk (no terminal forming) or Bag packing; RoHS compliant.

Typical Applications

• LED Driver Power Supplies — Use as a high-voltage smoothing capacitor in LED power modules where space is constrained and 400 V rating is required.
• General Purpose Power Filtering — Suitable for DC filtering and decoupling in high-voltage power supplies and converters.
• High‑Voltage Circuitry — Compact, polarized capacitance for energy storage and smoothing in compact high-voltage designs.

Unique Advantages

• High-Voltage Capability: 400 V rating enables use in higher-voltage DC rails without up-sizing the capacitor footprint.
• Compact Footprint: φ6.3×11 mm can and 2.5 mm lead spacing allow for dense through‑hole layouts where board space is limited.
• Designed for Long Life: 12,000 hours endurance at 105°C supports extended duty in thermally demanding applications.
• Practical Ripple Handling: Specified ripple current values at 120 Hz and 100 kHz provide predictable behavior across low- and high-frequency conditions.
• Predictable Loss Characteristics: tanδ = 0.24 at 20°C, 120 Hz gives a clear reference for dissipation in AC-biased designs.
• Manufacturing Flexibility: Choice of Bulk or Bag packing accommodates low-volume prototyping and higher-volume production workflows.
