UVY2V221MRD

The UVY2V221MRD is a radial-lead aluminum electrolytic capacitor rated for 350 V and 220 µF (±20%). It is a general-purpose, polarized radial-can capacitor designed for circuits that require high-voltage bulk capacitance and measurable ripple handling in a compact φ22 × 50 mm package.

Key engineering attributes include a wide operating temperature range of −40°C to +105°C, endurance of 2000 hours at 105°C, RoHS compliance, and radial lead mounting with 10 mm lead spacing. Note: this part is listed as End Of Life.

Key Features

• Electrical Rating — 350 V rated voltage with 220 µF nominal capacitance and ±20% tolerance for stable bulk energy storage at elevated voltages.
• Ripple Current Capability — Low-frequency ripple current 540 mA (120 Hz) and high-frequency ripple current 864 mA (10 kHz) to support smoothing and decoupling under AC ripple conditions.
• Leakage Current — Specified leakage current of 3180 µA, allowing designers to budget standby or leakage behavior into power budgets.
• Thermal and Endurance — Rated for −40°C to +105°C with 2000 hours endurance at 105°C to meet sustained high-temperature operating conditions.
• Package and Mounting — Radial can package (φ22 × 50 mm) with 10 mm lead spacing (±0.5 mm) for through-hole PCB designs; bulk and bag packing options are provided.
• Compliance and Polarity — Polarized aluminum electrolytic construction and RoHS-compliant materials.

Typical Applications

• General-purpose Power Circuits — Bulk smoothing and energy storage where 350 V and 220 µF are required.
• High-voltage DC Filtering — Filtering and decoupling in high-voltage sections of power supplies that benefit from measurable ripple-current capacity.
• Industrial Electronics — General-purpose use in industrial equipment designed for extended operation up to 105°C.
• Through-hole PCB Designs — Radial-lead mounting for straightforward assembly and replacement in legacy or serviceable boards.

Unique Advantages

• High-voltage capability: 350 V rating supports designs requiring elevated DC bus or HV smoothing without series stacking.
• Compact radial can: φ22 × 50 mm footprint balances capacitance and board space for through-hole implementations.
• Measured ripple performance: Specified ripple currents at both low and high frequencies enable predictable thermal and ripple handling.
• Wide operating temperature: −40°C to +105°C operation and 2000 h endurance at 105°C provide reliability in elevated-temperature environments.
• RoHS compliant: Materials conform to RoHS requirements for regulatory and environmental compatibility.

Why Choose UVY2V221MRD?

UVY2V221MRD is positioned for engineers who need a high-voltage, through-hole aluminum electrolytic capacitor with defined ripple capability and long-duration high-temperature endurance. Its combination of 350 V rating, 220 µF capacitance, and compact radial-can footprint make it well suited to general-purpose power filtering and high-voltage DC applications where reliability and predictable electrical behavior are required.

Although this part is End Of Life, its documented specifications—including leakage current, ripple ratings at 120 Hz and 10 kHz, lead spacing, and packaging options—provide clear evaluation criteria for replacement selection or cross-referencing in existing designs.
