ULD2E180MPD

The ULD2E180MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's ULD series, offering 18 µF capacitance at a 250 V rating in a compact φ10 × 16 mm can. Designed for general-purpose power applications, it combines a polarized radial package and long-life endurance for use in power-supply and LED lighting circuits.

Key engineering attributes include a wide operating temperature range of -40°C to 105°C, rated endurance of 20,000 hours at 105°C, RoHS compliance, and packaging options suitable for manual or automated handling (bulk or bag packing).

Key Features

• Capacitance & Voltage — 18 µF nominal capacitance with a rated voltage of 250 V, suitable for DC filtering and energy storage in mid-voltage designs.
• Long-Life Endurance — Endurance specified at 20,000 hours at 105°C under rated conditions, reflecting the ULD series’ long-life design intent.
• Wide Temperature Range — Rated for operation from -40°C to 105°C to support higher ambient and elevated operating-temperature environments.
• Ripple Current Capability — Low-frequency ripple current of 129 mA (120 Hz) and high-frequency ripple current of 245.1 mA (100 kHz) to support ripple-handling in power supplies.
• Electrical Losses & Leakage — Tan δ (loss tangent) of 0.24 measured at 20°C, 120 Hz, and an initial leakage current specified at 280 µA.
• Package & Mounting — Radial lead, polarized can with dimensions φ10 × 16L and 5 mm lead spacing (±0.5 mm); offered in Bulk (No Terminal Forming) or Bag Packing.
• Tolerance — Capacitance tolerance of -20% to +20% at 20°C, 120 Hz for predictable selection in designs.
• Environmental Compliance — RoHS compliant as provided in the product information.
• Product Status — Listed as End Of Life.

Typical Applications

• LED driver power supplies — Provides DC filtering and smoothing in LED lighting power supplies where long-life operation at elevated temperatures is required.
• General-purpose power filtering — Suitable for bulk decoupling and ripple filtering in mid-voltage DC rails up to 250 V.
• Industrial and control electronics — Useful in control power modules that demand stable capacitance and endurance at up to 105°C ambient.
• Consumer and appliance power supplies — Fits compact radial designs requiring moderate capacitance, voltage rating, and long operational life.

Unique Advantages

• Extended operational life: 20,000-hour rated endurance at 105°C reduces replacement frequency and supports longer service intervals.
• Compact radial can: φ10 × 16 mm package and 5 mm lead spacing deliver a small footprint for space-constrained through-hole designs.
• Dual-frequency ripple handling: Specified ripple currents at both 120 Hz and 100 kHz address performance across low- and high-frequency power conditions.
• Measurable electrical characteristics: Specified tan δ (0.24 at 20°C, 120 Hz) and defined leakage current (280 µA) aid predictable thermal and loss budgeting.
• RoHS compliant: Meets environmental directive requirements for lead-free materials and processes as listed.
• Flexible packaging: Available in bulk (no terminal forming) or bag packing to support various assembly and handling workflows.
