UHV1E221MPD

The UHV1E221MPD is a Nichicon UHV series aluminum electrolytic capacitor in a radial-lead can, designed for general-purpose power applications that require compact size with high ripple handling and low impedance. With a rated capacitance of 220 µF at 25 V and a rugged -40 °C to 105 °C operating range, it targets circuits where ripple current capability and stable performance over temperature and time are important.

Key Features

• Capacitance and Voltage — 220 µF rated capacitance at 25 V for bulk filtering and decoupling in compact layouts.
• Low Impedance — Specified impedance of 181 mΩ supports low-impedance decoupling and improved high-frequency performance.
• High Ripple Current — Low-frequency ripple current 405 mA (120 Hz) and high-frequency ripple current 810 mA (100 kHz) enable effective filtering in switching supplies and high-frequency converters.
• Loss Tangent (tan δ) — tan δ = 0.13 measured at 20 °C, 120 Hz, 25 V, for predictable dissipation characteristics.
• Reliability and Lifetime — Endurance rated 6000 hours at 105 °C under rated conditions, suitable for long-life power applications.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly in space-constrained designs.
• Leakage Current — Specified leakage current of 55 µA; datasheet also specifies leakage current limit as ≤ 0.01CV (µA) after 2 minutes at 20 °C.
• RoHS Compliant — Meets RoHS requirements for restricted substances.
• Packaging and Availability — Supplied in bulk/no terminal forming or bag packing; status: mass production.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where high ripple current capability and low impedance improve regulator stability.
• DC–DC Converters — Local decoupling and energy storage for converters operating at higher switching frequencies, leveraging the capacitor’s low impedance at high frequency.
• Industrial and General-Purpose Electronics — General-purpose power filtering in compact through-hole assemblies across a broad temperature range (-40 °C to 105 °C).

Unique Advantages

• High ripple handling in a small footprint — 405 mA (120 Hz) and 810 mA (100 kHz) ripple ratings combined with a φ8 × 11.5 mm can enable smaller board area without sacrificing performance.
• Predictable thermal and electrical behavior — tan δ specified at standard test conditions and a defined 6000 h endurance at 105 °C support design validation and lifetime planning.
• Low-impedance performance — 181 mΩ impedance helps reduce voltage ripple and improve transient response in power circuits.
• Through-hole robustness — Radial-lead mounting and specified lead spacing simplify mechanical assembly and replacement in serviceable designs.
• Traceable quality — Part of Nichicon’s UHV series with documented specifications and mass-production availability for consistent supply.
