UVY2E221MHD

The UVY2E221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UVY series, offering a 220 µF capacitance at a 250 V rating. Engineered for general-purpose power circuits, it delivers bulk energy storage and filtering capability in a compact φ18 × 35.5 mm can.

Key value comes from its wide operating temperature range (−40 °C to 105 °C), rated endurance of 2000 hours at 105 °C, and measured ripple current performance across low and high frequencies—making it suitable for designs that require stable behavior over temperature and time.

Key Features

• Capacitance & Tolerance — 220 µF with a tolerance of −20% to +20%, specified at 120 Hz and 20 °C.
• Voltage Rating — 250 V rated voltage for medium-voltage general-purpose applications.
• Radial Lead Package — Radial can package with lead spacing of 7.5 mm (±0.5 mm) for through-hole mounting and ease of assembly.
• Thermal Range & Endurance — Operating temperature −40 °C to 105 °C with a life rating of 2000 hours at 105 °C.
• Ripple Current Performance — Low-frequency ripple current: 485 mA at 120 Hz; high-frequency ripple current: 776 mA at 10 kHz.
• Leakage & Dissipation — Leakage current listed at 2300 µA; tangent of loss angle (tan δ) = 0.2 measured at 20 °C, 120 Hz.
• Compact Dimensions — Case size φ18 × 35.5 mm with lead spacing 7.5 mm, suitable for space-conscious through-hole layouts.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing. Product status: Mass Production.

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and smoothing where a 250 V, 220 µF polarized capacitor is required across −40 °C to 105 °C.
• Power supply filtering — Supports ripple current handling at both low (120 Hz) and high (10 kHz) frequencies for decoupling and filtering duties.
• Industrial and commercial equipment — Suitable for applications that demand long endurance (2000 hours at 105 °C) and stable performance over a wide temperature range.

Unique Advantages

• High-voltage capability: 250 V rating enables use in medium-voltage circuits without upsizing capacitance form factor.
• Wide operating temperature span: −40 °C to 105 °C supports designs exposed to varying thermal environments.
• Long endurance at elevated temperature: Rated for 2000 hours at 105 °C, giving predictable aging characteristics for maintenance planning.
• Frequency-aware ripple performance: Specified ripple currents at 120 Hz and 10 kHz (485 mA and 776 mA respectively) help designers size thermal management and ripple margins.
• Compact radial can: φ18 × 35.5 mm construction with 7.5 mm lead spacing balances capacitance with PCB real estate for through-hole assemblies.
• RoHS compliant & production-ready: Meets RoHS requirements and is available in mass-production quantities with bulk or bag packing options.
