UHV1E222MHD

The UHV1E222MHD is a Nichicon UHV series radial-lead aluminum electrolytic capacitor offering 2200 µF capacitance at 25 V in a compact φ12.5 × 30.5 mm can. It is a high-reliability, high-ripple, low-impedance type designed for general-purpose electronic applications that require robust bulk capacitance in a small footprint.

Engineered for elevated operating conditions, this part is specified for continuous operation from −40°C to 105°C with a rated lifetime of 6000 hours at 105°C, making it suitable where long endurance and stable performance under ripple loading are important.

Key Features

• High Capacitance: 2200 µF nominal capacitance with ±20% tolerance provides substantial bulk energy storage for smoothing and decoupling.
• 25 V Rated Voltage: Rated for 25 V operation to support a wide range of low-voltage power systems.
• High Ripple Current Handling: Rated ripple currents of 2.846 A at 120 Hz and 3.795 A at 100 kHz enable effective performance under AC ripple stress.
• Low Impedance: Specified impedance of 31 mΩ helps minimize voltage drop under dynamic loads and supports improved high-frequency behavior.
• Compact Radial Package: φ12.5 × 30.5 mm can with 5.0 mm lead spacing (±0.5 mm) provides a small, easy-to-mount radial-lead form factor for through-hole assemblies.
• Wide Temperature Range and Long Life: Operating range −40°C to 105°C and endurance of 6000 hours at 105°C for reliable long-term operation in demanding environments.
• Leakage and Loss Characteristics: Leakage current rated at 550 µA and tangent of loss angle (tan δ) 0.15 (measured at 20°C, 120 Hz) for predictable loss and self-heating behavior.
• RoHS Compliant: Conforms to RoHS requirements as indicated in product data.

Typical Applications

• Power Supplies: Bulk capacitance and high ripple-current capability support input/output filtering and energy storage in low-voltage power converters and regulators.
• Industrial Controls: Stable operation to 105°C and long endurance make the part suitable for control electronics exposed to elevated temperatures and continuous ripple stress.
• Consumer and Commercial Electronics: Compact radial can and high capacitance deliver effective smoothing and decoupling in space-constrained assemblies requiring reliable bulk capacitance.

Unique Advantages

• High Ripple Tolerance: Quantified ripple ratings at both 120 Hz and 100 kHz let designers size capacitors based on actual frequency conditions and thermal margin.
• Low-Impedance Performance: 31 mΩ impedance reduces voltage droop under load, improving transient response in power systems.
• Small Footprint, High Capacity: 2200 µF in a φ12.5 × 30.5 mm package conserves board space while delivering significant bulk energy storage.
• Long-Term Reliability: 6000-hour endurance at 105°C provides a predictable lifecycle for designs with continuous elevated-temperature operation.
• Clear Electrical Characterization: Specified tan δ, leakage current, and frequency-dependent ripple coefficients enable accurate thermal and performance modeling.
• Through-Hole Simplicity: Radial-lead package with 5.0 mm lead spacing simplifies placement and soldering in conventional assembly flows and prototyping.
