ULD2C220MPD

The ULD2C220MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's ULD series, offering a compact φ10 × 12.5 mm can with 5 mm lead spacing. Designed as a long-life, general-purpose capacitor, it is suited for power-supply applications such as LED lighting and other equipment that require reliable smoothing and decoupling at elevated temperatures.

Key strengths include a 160 V rated voltage, 22 µF capacitance with ±20% tolerance, rated endurance at elevated temperature, and RoHS compliance—providing a compact, durable option for engineers specifying electrolytic capacitance in tight assemblies.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a rated voltage of 160 V and a tolerance of -20% to +20% for predictable energy storage and decoupling.
• Long-Life Endurance — Rated life of 15,000 hours at +105°C for the φ10×12.5L size, supporting extended operation in high-temperature environments.
• Thermal Range — Operating temperature from -40°C to +105°C to cover a wide range of ambient conditions.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.24 at 20°C, 120 Hz and a measured leakage current of 240.8 µA, enabling predictable dissipation and minimal stand-by current.
• Ripple Current Capability — Low-frequency ripple current 121 mA at 120 Hz and high-frequency ripple current 217.8 mA at 100 kHz for handling AC stress on power rails.
• Package & Mounting — Radial lead / can package, size φ10 × 12.5 mm, lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packing (no terminal forming) for straightforward through-hole assembly.
• Regulatory — RoHS compliant.

Typical Applications

• LED Lighting Power Supplies — Provides smoothing and filtering in LED driver circuits where the ULD series is explicitly noted as suited for power-supply use.
• General-Purpose Power Supply Filtering — Useful for bulk decoupling and smoothing in a variety of power-supply designs requiring a 160 V rated capacitor.
• Industrial and Instrumentation Electronics — Compact radial package and extended high-temperature life make it suitable for control and instrumentation power rails operating in elevated ambient temperatures.

Unique Advantages

• Extended High-Temperature Life — 15,000 hours at +105°C for the φ10×12.5L package helps maintain capacitance and reliability in thermally demanding designs.
• Compact Footprint — φ10 × 12.5 mm can diameter and short body length deliver space savings for dense through-hole assemblies.
• Measured Ripple Handling — Specified ripple current values at both low (120 Hz) and high (100 kHz) frequencies provide designers with quantifiable AC stress limits for power-rail design and thermal planning.
• Predictable Electrical Losses — Specified tan δ at measurement conditions (0.24 at 20°C, 120 Hz) offers clear data for loss and heating calculations.
• Supply-Friendly Packaging — Available in bulk or bag packing (no terminal forming) to match common procurement and assembly workflows.
• RoHS Compliance — Conforms to RoHS directives for use in regulated electronic assemblies.
