ULD1J220MED

The ULD1J220MED is a miniature aluminum electrolytic capacitor from Nichicon's ULD series, engineered for long-life operation in compact power designs. It delivers 22 µF at 63 V in a radial can package optimized for general-purpose power filtering and is particularly suited for power supplies in LED lighting applications.

Designed for reliability under elevated temperature, this device is rated for operation from -40 °C to +105 °C and is RoHS compliant, offering a durable, leaded solution where long operating life and tight board footprint are required.

Key Features

• Electrolytic Core — Aluminum electrolytic construction providing 22 µF capacitance at a 63 V rated voltage for general-purpose power decoupling and smoothing.
• Long-Life Endurance — Rated for 10000 hours at +105 °C under load life conditions, supporting sustained operation in high-temperature environments.
• Temperature Range — Operates from -40 °C to +105 °C to accommodate a wide range of thermal environments.
• Compact Radial Can Package — Radial lead, can-style package with overall dimensions L: 1.1 × D: 0.63 cm and 2.5 mm lead spacing for space-constrained PCB layouts.
• Polarized with ±20% Tolerance — Polar capacitor with capacitance tolerance of -20% to +20% suitable for typical power supply circuits.
• Ripple Current Capability — Specified ripple current of 93.5 mA at 120 Hz and 170 mA at 100 kHz for handling AC ripple in DC power rails.
• RoHS Compliant — Meets RoHS directive requirements for reduced hazardous substances.

Typical Applications

• LED Lighting Power Supplies — Provides stable filtering and smoothing in LED driver circuits where long lifetime at elevated temperature is required.
• General Purpose Power Filtering — Used for decoupling and bulk capacitance in compact power modules and PCB power rails.
• Compact Consumer Electronics — Small footprint and radial lead form factor make it suitable for space-limited assemblies requiring reliable long-term performance.

Unique Advantages

• Extended High-Temperature Life: Rated for 10000 hours at +105 °C, enabling designs that must maintain capacitance and leakage performance under sustained thermal stress.
• Small Board Footprint: Compact dimensions (1.1 × 0.63 cm) and 2.5 mm lead spacing reduce PCB area compared with larger radial capacitors.
• Measured Ripple Performance: Specified ripple currents at both low (120 Hz) and high (100 kHz) frequencies allow predictable thermal and lifetime planning in power designs.
• Series-Level Reliability: Part of Nichicon’s ULD long-life family, benefiting from series specifications for endurance and leakage characteristics.
• Regulatory Compliance: RoHS compliant for use in products targeting regions requiring restricted substance compliance.
