ULD2G3R3MPD

The ULD2G3R3MPD from Nichicon is a radial lead, aluminum electrolytic capacitor in the ULD series designed for general-purpose power applications. It delivers 3.3 µF capacitance at a 400 V rating in a compact φ8 × 11.5 mm can and is offered in a bulk/bag packing option.

Targeted uses include power-supply smoothing and LED lighting power modules where a compact, long-life polarized capacitor is required. Key technical attributes include a rated 400 V working voltage, a measured leakage current of 152.8 µA, and endurance specified for 15,000 hours at 105°C for the φ8×11.5L size.

Key Features

• Electrical Rating – 400 V, 3.3 µF Rated capacitance of 3.3 µF with a −20% to +20% tolerance at 120 Hz, 20°C, and a 400 V working voltage for high-voltage DC service.
• Loss Characteristics Tangent of loss angle (tan δ) specified at 0.24 (measured at 20°C, 120 Hz, 400 V), supporting predictable AC loss behavior in filtering and smoothing roles.
• Ripple Current Capability Frequency-specific ripple current ratings of 47 mA at 120 Hz and 94 mA at 100 kHz provide designers with documented ripple performance for both low- and high-frequency environments.
• Leakage Current Measured leakage current of 152.8 µA (per product data) for predictable bias current budgeting in power designs.
• Long Life Endurance Endurance rated at 15,000 hours at 105°C for the φ8×11.5L case size, reflecting suitability for extended operation in elevated-temperature applications.
• Compact Radial Can Package φ8 × 11.5 mm can, radial lead mounting with 3.5 mm lead spacing (±0.5 mm), suited to through-hole assembly and space-constrained layouts.
• Operating Temperature Range Specified for −40°C to +105°C operation, supporting demanding thermal environments.
• Compliance and Packaging RoHS-compliant and available in bulk/no terminal forming or bag packing; product is in mass production as part of Nichicon’s ULD series.

Typical Applications

• LED Lighting Power Supplies Suited for DC smoothing and energy storage in LED driver circuits where long life at elevated temperature is required.
• Power Supply Filtering Used for high-voltage smoothing and decoupling in compact power-supply modules leveraging the 400 V rating and documented ripple current specs.
• Industrial Power Electronics Applicable in general-purpose industrial power circuitry requiring a polarized capacitor with verified endurance at 105°C.

Unique Advantages

• High Voltage Capability: 400 V rating enables use in higher-voltage DC circuits without up-rating parts.
• Compact Footprint: φ8 × 11.5 mm can and 3.5 mm lead spacing allow integration into dense, through-hole assemblies.
• Documented Endurance: 15,000 hours at 105°C (φ8×11.5L) supports longer service intervals in thermal-stressed applications.
• Measured Ripple and Loss Data: Published ripple current values (120 Hz and 100 kHz) and tan δ (0.24 at 120 Hz, 20°C) enable predictable thermal and AC-loss budgeting.
• Polarized Design for Power Roles: Radial lead, polarized construction targets classic DC smoothing and energy-storage functions.
• RoHS Compliance and Production Availability: RoHS-compliant and mass-produced as part of the Nichicon ULD series for reliable sourcing.
