ULD2A220MPD

The ULD2A220MPD is a Nichicon ULD series radial-lead aluminum electrolytic capacitor rated 22 µF at 100 V. It is a miniature, polarized can-style capacitor designed for general-purpose power filtering and decoupling in compact, through-hole assemblies.

The part delivers long-life performance with a specified endurance of 10000 hours at 105°C, a wide operating temperature range from −40°C to 105°C, and RoHS compliance. It is offered in bulk/bag packaging and is in mass production.

Key Features

• Rated Capacitance & Voltage — 22 µF nominal capacitance at a rated voltage of 100 V for power supply filtering and decoupling tasks.
• Long-Life Endurance — Specified life of 10000 hours at 105°C under rated conditions, providing predictable lifetime performance for sustained operation.
• Temperature Range — Operates from −40°C to 105°C to suit a wide range of environmental conditions.
• Loss Angle (tan δ) — tanδ = 0.15 measured at 20°C, 120 Hz (at 100 V), enabling selection based on dissipation characteristics.
• Ripple Current Ratings — Low-frequency ripple current 126.5 mA (120 Hz) and high-frequency ripple current 230 mA (100 kHz), supporting both mains-frequency and switching applications.
• Leakage Current — Specified leakage current of 22 µA, useful for low-standby and precision power designs.
• Compact Radial Can — Package size φ8 × 11.5 mm with 3.5 mm lead spacing (±0.5 mm tolerance) for compact through-hole layouts.
• Polarized, Through-Hole Mounting — Radial lead configuration and polarized construction for reliable PCB mounting in conventional assembly flows.
• Regulatory — RoHS compliant.

Typical Applications

• LED lighting power supplies — ULD series is suited for power supplies for LED lighting; this part provides filtering and energy storage in compact driver circuits.
• General-purpose power filtering — Decoupling and smoothing in small power supplies and regulator outputs where a 100 V margin is required.
• Compact through-hole modules — Space-constrained, board-level modules that require a miniature radial electrolytic with defined lead spacing and compact can dimensions.

Unique Advantages

• Small footprint for space-limited designs — φ8 × 11.5 mm can and 3.5 mm lead spacing let you place reliable bulk capacitance in tight layouts.
• Long-term thermal endurance — 10000 hours at 105°C provides measurable lifetime expectations for sustained high-temperature operation.
• Dual-frequency ripple capability — Specified ripple current at both 120 Hz and 100 kHz supports use across linear and switching regulator environments.
• Low leakage for stable biasing — 22 µA leakage current helps maintain low standby losses and predictable circuit behavior.
• Measurable dissipation (tan δ) — tanδ specified at 120 Hz and 20°C enables engineers to assess ESR-related dissipation and thermal planning.
• Manufactured at scale — Product is in mass production, simplifying procurement for volume projects.

Why Choose ULD2A220MPD?

ULD2A220MPD combines a compact radial can footprint with a 100 V rating and a 22 µF capacitance value, making it a practical choice when higher voltage margin and space efficiency are required. Its 10000-hour endurance at 105°C, defined ripple current specifications, and low leakage current deliver predictable electrical and thermal performance for power-supply and driver designs.

This part is well suited to engineers and procurement teams designing compact, through-hole power modules and LED driver supplies who need a RoHS-compliant, long-life aluminum electrolytic capacitor from the Nichicon ULD series.
