ULD2D3R3MED

The ULD2D3R3MED is a Nichicon ULD series radial lead aluminum electrolytic capacitor offering 3.3 µF capacitance at a 200 V rating in a compact, miniature can. It is a polarized, general‑purpose component designed for applications that require a high‑voltage, long‑life electrolytic solution in tight PCB real estate.

Engineered as part of Nichicon’s long‑life ULD family, this part combines a wide operating range (‑40 °C to 105 °C) and a 12,000‑hour endurance rating at 105 °C to support sustained performance in power supply and LED driver environments.

Key Features

• Capacitance & Tolerance: 3.3 µF nominal with tolerance −20% to +20% for predictable filtering and decoupling performance.
• Rated Voltage: 200 V DC rated for higher‑voltage power sections and rail decoupling.
• Long‑Life Endurance: Specified life of 12,000 hours at 105 °C to support extended operational duty in demanding thermal environments.
• Temperature Range: Operational from −40 °C to 105 °C to accommodate a broad range of ambient conditions.
• Loss Tangent (tan δ): tan δ = 0.24 measured at 20 °C, 120 Hz, 200 V—useful for assessing ESR‑related losses in AC/ripple conditions.
• Ripple Current Capability: 42 mA at 120 Hz (low frequency) and 84 mA at 100 kHz (high frequency) for AC ripple handling in power applications.
• Leakage Current: 106 µA specified leakage current for quiescent performance considerations.
• Compact Radial Package: Miniature can with dimensions φ6.3 × 11 mm, radial lead mounting, and 2.5 mm lead spacing (±0.5 mm) for through‑hole placement.
• Packaging & Compliance: Available in bulk (no terminal forming) or bag packing; RoHS compliant.
• Product Status: End Of Life—please verify availability when planning production use.

Typical Applications

• Power Supplies: Bulk and high‑voltage rail decoupling where 200 V rating and long endurance are required.
• LED Drivers and Lighting Power: Suited for LED driver power sections as part of the Nichicon ULD long‑life series for sustained operation.
• General Purpose Electronics: Filtering, smoothing, and decoupling in compact through‑hole designs with limited PCB area.
• Sensor and Instrumentation Circuits: Small form‑factor energy storage and noise suppression in measurement and control circuitry.

Unique Advantages

• Compact long‑life design: φ6.3 × 11 mm miniature can plus a 12,000‑hour rating at 105 °C enables durable performance in space‑constrained assemblies.
• High voltage capability: 200 V rating supports higher‑voltage rails without requiring larger components.
• Broad temperature tolerance: −40 °C to 105 °C operation maintains capacitance and reliability across a wide thermal envelope.
• Dual‑frequency ripple management: Specified ripple currents at both 120 Hz and 100 kHz provide data to size and verify ripple handling in low‑ and high‑frequency power circuits.
• Predictable leakage and loss characteristics: Specified leakage current (106 µA) and tan δ (0.24 at 120 Hz) aid in system power budgeting and thermal design.
• RoHS compliant packaging options: Bulk and bag packing choices simplify handling and PCBA integration while meeting RoHS requirements.
