UVZ2V221MRD

The UVZ2V221MRD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UVZ series, rated at 220 µF and 350 V. It is a polarized, general-purpose capacitor designed for higher-voltage circuits where bulk capacitance, voltage withstand and wide operating temperature are required.

Key device characteristics include a wide operating temperature range of -40°C to 105°C, 2000 hours endurance at 105°C, a compact φ22 × 50 mm can size with 10 mm lead spacing, and RoHS compliance. Status: End Of Life.

Key Features

• Capacitance & Voltage: 220 µF capacitance with a rated voltage of 350 V and a tolerance of -20% to +20%.
• Temperature and Endurance: Operating range from -40°C to 105°C with an endurance specification of 2000 hours at 105°C.
• Loss Angle / Dissipation Factor: tan δ (DF) = 0.25 measured at 20°C, 120 Hz, providing a documented dissipation characteristic for design verification.
• Ripple Current Ratings: Low-frequency ripple current 620 mA (120 Hz) and high-frequency ripple current 992 mA (10 kHz), enabling assessment of ripple-handling capability across frequencies.
• Leakage Current: Specified leakage current of 3180 µA for initial selection and safety margin calculations.
• Package & Mounting: Radial-lead can, size φ22 × 50 mm, lead spacing 10 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Regulatory: RoHS compliant.

Typical Applications

• High-voltage power supplies: Use where 350 V rated bulk capacitance is required and wide operating temperature is needed.
• Industrial electronics: General-purpose high-voltage support in industrial control and auxiliary power modules operating up to 105°C.
• Energy conversion & power conditioning: Systems that need documented ripple-current capability at both low and high frequencies.

Unique Advantages

• High working voltage (350 V): Supports higher-voltage designs without series stacking of lower-voltage capacitors.
• Wide operating temperature window: -40°C to 105°C operation accommodates a broad set of environmental conditions.
• Documented endurance: 2000 hours at 105°C gives a clear reliability target for thermal-stress planning.
• Frequency-aware ripple specifications: Separate ripple current ratings for 120 Hz and 10 kHz help match the part to both mains-frequency and higher-frequency ripple environments.
• Standard radial can footprint: φ22 × 50 mm size and 10 mm lead spacing allow straightforward mechanical integration into existing radial-can layouts.
• RoHS compliant: Conforms to current RoHS requirements for environmental compliance in supply chains.
