URZ2C221MRD

The URZ2C221MRD is a radial-lead aluminum electrolytic capacitor in Nichicon’s URZ series, offering 220 µF capacitance with a 16 V rated voltage and ±20% tolerance. It combines a compact, low-profile can (φ20 × 25 mm) with radial leads and a 10 mm lead spacing for straightforward through-hole mounting.

Designed for general-purpose electronic equipment, the part delivers specified ripple handling and a defined endurance of 1000 hours at 105°C, making it suitable where stable capacitance, polarized energy storage, and thermal endurance matter.

Key Features

• Capacitance & Tolerance: 220 µF nominal with ±20% tolerance at 120 Hz, 20°C for predictable energy storage and decoupling.
• Rated Voltage: 16 V working voltage suitable for a wide range of low-voltage designs.
• Ripple Current Performance: 550 mA (120 Hz) and 880 mA (10 kHz) ripple current ratings to handle both low- and high-frequency ripple stresses when specified thermal conditions are met.
• Thermal Endurance: Specified 1000 hours life at 105°C, providing measurable high-temperature endurance for demanding ambient conditions.
• Leakage Current: Leakage specified at 1508 µA, enabling designers to budget for standby and leakage behavior in system power budgets.
• Package & Mounting: Radial, can-style package (φ20 × 25 mm) with 10 mm lead spacing and bulk/bag packing options for manual or automated assembly processes.
• Operating Temperature Range: Rated for −40°C to 105°C to support a broad range of environmental conditions.
• Polarized Device: Polarized aluminum electrolytic construction—appropriate for DC energy storage and decoupling.

Typical Applications

• General-purpose electronic equipment: Used for bulk energy storage, smoothing and decoupling in a variety of consumer and industrial assemblies.
• Power supply filtering: Provides capacitance and specified ripple handling for low-voltage DC rails in power conversion and regulation circuits.
• PCB through-hole assemblies: Radial lead format and standard 10 mm lead spacing make it straightforward to integrate into through-hole or mixed-technology boards.

Unique Advantages

• Compact, low-profile package: φ20 × 25 mm can offers significant capacitance in a space-conscious radial format.
• Defined high-temperature life: 1000 hours at 105°C gives a measurable endurance metric for thermal budgeting and long-term reliability planning.
• Broad ripple handling: Separate low- and high-frequency ripple ratings (550 mA @120 Hz, 880 mA @10 kHz) allow designers to evaluate performance across frequency domains.
• Simple mounting and handling: Radial leads with 10 mm spacing and bulk/bag packaging options support flexible assembly workflows.
• Clear electrical characterization: Specified leakage current and capacitance tolerance enable predictable behavior in power-sensitive applications.
