UPS2C221MHD

The UPS2C221MHD is a miniature, low-impedance aluminum electrolytic capacitor designed for switching power supplies and general-purpose power filtering. It is a polarized, radial-lead can offering 220 µF capacitance at a 160 V rating, packaged for through-hole mounting.

Key platform attributes include a wide operating temperature range, RoHS compliance, and a long endurance rating at elevated temperature—making it suitable for compact power designs that require stable capacitance and ripple handling in demanding environments.

Key Features

• Electrical Performance  220 µF capacitance with a 160 V rated voltage and ±20% tolerance, providing energy storage for higher-voltage power rails.
• Low-Impedance Design  Specified as a low-impedance type and rated with ripple current capability of 500 mA at 120 Hz and 800 mA at 10 kHz, supporting switching power supply ripple smoothing.
• Temperature Range & Endurance  Operational from −40 °C to 105 °C with a guaranteed lifetime of 3000 hours at 105 °C under rated conditions, enabling reliable performance under elevated temperatures.
• Package & Mounting  Radial can package with radial leads, 7.5 mm lead spacing, dimensions L: 3.55 × D: 1.8 cm and a maximum seated height of 1.398 inch for compact through-hole assemblies.
• Leakage & Loss Characteristics  Datasheet specifies leakage current limits and loss angle characteristics for the UPS series (e.g., leakage current ≤ 0.03CV (µA) after 1 minute at 20 °C), supporting predictable DC performance.
• Environmental Compliance  Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies  Provides ripple smoothing and energy buffering on high-voltage rails in switching regulators and power conversion stages.
• General-Purpose Power Filtering  Suited for bulk decoupling and smoothing in through-hole designs where compact size and 160 V rating are required.
• Industrial Power Modules  Useful in compact industrial power assemblies that need stable capacitance across −40 °C to 105 °C and rated endurance at elevated temperature.

Unique Advantages

• Compact, high-voltage storage: 220 µF at 160 V offers significant capacitance in a miniature radial can for space-constrained designs.
• Designed for switching environments: Low-impedance construction plus specified ripple current ratings at 120 Hz and 10 kHz help manage switching-induced ripple.
• Extended elevated-temperature endurance: 3000 hours rated life at 105 °C supports longer service intervals in hot operating conditions.
• Through-hole compatibility: Radial lead spacing and can package simplify PCB layout and mechanical mounting for traditional assembly processes.
• Predictable DC behavior: Datasheet leakage and tan δ specifications allow engineers to size and validate designs with measurable parameters.
• RoHS compliant: Meets current RoHS requirements for environmental regulatory compatibility.
