UPS2D221MRD6

The UPS2D221MRD6 is a miniature, low-impedance aluminum electrolytic capacitor from Nichicon’s UPS series, designed primarily for switching power supplies and general-purpose power filtering. It combines a 220 µF capacitance with a 200 V rated voltage in a compact radial-can package.

Key value comes from its wide operating capability and durability: a -40°C to 105°C operating range, rated ripple current performance across frequencies, and a specified endurance of 3000 hours at 105°C, making it suitable for applications that require stable decoupling and smoothing under elevated temperatures.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with a 200 V rated voltage, suitable where higher DC working voltage is required.
• Low Impedance Design — Marketed as low impedance and targeted for switching power supplies, providing effective smoothing and decoupling in high-frequency power environments.
• Wide Operating Temperature — Specified for operation from -40°C to 105°C to support a broad range of environmental conditions.
• High-Temperature Endurance — Rated lifetime of 3000 hours at 105°C, supporting long-term operation under thermal stress.
• Ripple Current Performance — Rated ripple current of 515 mA at 120 Hz and 824 mA at 10 kHz, delivering specified AC current capability across common power-supply frequencies.
• Radial Lead Package — Radial, can-style construction with 1.0 cm lead spacing and a compact footprint (L: 3.5 × D: 2 cm), for through-hole PCB assembly.
• Polarized with Standard Tolerance — Polarized capacitor with ±20% capacitance tolerance at 20°C, 120 Hz.
• RoHS Compliant — Complies with RoHS directives (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• Switching Power Supplies — Smoothing and decoupling in switch-mode power converter outputs where low impedance and high voltage handling are required.
• General-Purpose Power Filtering — Bulk and local energy storage for general-purpose electronic equipment requiring stable capacitance under elevated temperatures.
• Through-Hole PCB Assemblies — Radial-lead can package for conventional through-hole mounting and assembly processes.

Unique Advantages

• High-Voltage in a Compact Footprint — 200 V rating combined with a 3.5 × 2 cm can size delivers higher DC capability without a large board footprint.
• Designed for Switching Environments — Low-impedance characteristics and specified ripple current values provide measurable benefits in high-frequency power stages.
• Wide Temperature Operation — Operation from -40°C to 105°C supports equipment used in varied thermal conditions.
• Extended High-Temperature Life — 3000-hour endurance at 105°C offers predictable longevity for demanding applications.
• Through-Hole Reliability — Radial lead, can-style package provides mechanical robustness for assemblies that prefer through-hole components.
• Regulatory Compliance — RoHS conformity reduces supply-chain concerns related to restricted substances.
