UHW1H272MHD

The UHW1H272MHD is a high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series. It is a radial-lead, polarized capacitor rated at 2700 µF and 50 V, optimized for general-purpose power applications requiring elevated temperature endurance and robust ripple handling.

Built for demanding environments, this φ16 × 35.5 mm can delivers low impedance and high ripple-current capability while supporting continuous operation to 105 °C with a rated life of 10,000 hours at that temperature.

Key Features

• Capacitance & Tolerance: 2700 µF nominal with ±20% tolerance (measured at 120 Hz, 20 °C), suitable for bulk energy storage and filtering on a 50 V rail.
• Voltage Rating: 50 V DC rated voltage for mid-voltage power rails and filter stages.
• High Temperature Endurance: Rated for operation from −40 °C to +105 °C with a specified lifetime of 10,000 hours at 105 °C.
• Low Impedance: Characteristic impedance of 54 mOhm, supporting effective decoupling and low-loss operation in power circuits.
• High Ripple Current Capability: Rated ripple current of 2.7 A at 120 Hz and 3.6 A at 10 kHz, enabling reliable handling of AC components on DC rails.
• Radial Lead Package: φ16 × 35.5 mm aluminum can with 7.5 mm lead spacing (±0.5 mm) and standard radial-lead mounting for through-hole assemblies.
• Compliance & Marking: RoHS compliant; parts are printed with white lettering on a black sleeve for clear identification.
• Packaging Options: Supplied in bulk (no terminal forming) or bag packing to suit production and prototyping needs.

Typical Applications

• Power supply smoothing and bulk storage: 2700 µF capacitance and low impedance provide effective energy storage and smoothing on 50 V rails.
• DC–DC converter output filters: High ripple-current rating and low impedance support stable output filtering in switching power supplies.
• Industrial and control electronics: 105 °C operation and 10,000-hour life at that temperature make this capacitor suitable for long-lived industrial power modules and controllers.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 2.7 A (120 Hz) and 3.6 A (10 kHz) reduce heating and extend service life under AC stress.
• Low ESR/Impedance: 54 mOhm impedance supports lower losses and improved voltage stability in power circuits.
• Elevated operating temperature and long life: −40 °C to +105 °C rating with 10,000 hours endurance at 105 °C provides predictable long-term performance in thermally demanding systems.
• Compact radial can: φ16 × 35.5 mm package with 7.5 mm lead spacing simplifies through-hole integration while keeping board footprint modest.
• RoHS compliant and clearly marked: Environmentally compliant construction and white-on-black sleeve marking ease assembly and traceability.
