UHW1C272MHD

The UHW1C272MHD is a miniature, high-reliability aluminum electrolytic capacitor in the Nichicon UHW series. It is a radial-lead, polarized capacitor specified at 2700 µF and 16 V, designed for general-purpose power applications that require high ripple current handling in a compact can.

Key value propositions include low impedance at higher frequencies and extended endurance—rated for 10,000 hours at 105°C—making it suitable for designs that demand sustained performance under elevated temperature and ripple conditions.

Key Features

• Capacitance & Voltage: 2.7 mF (2700 µF) nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20% for predictable bulk energy storage.
• High Ripple Current Capability: Low-frequency ripple current 2.4 A (120 Hz) and high-frequency ripple current 3.2 A (10 kHz), enabling effective filtering and smoothing under varying ripple spectra.
• Low Impedance: Impedance of 45 mΩ and series design intent for lower impedance at high frequency ranges as described in the UHW series datasheet.
• Loss Characteristics: Dissipation factor (tan δ) 0.17 measured at 20°C, 120 Hz. (Note: the series datasheet specifies adding 0.02 to tan δ for capacitances greater than 1000 µF per each 1000 µF increment.)
• Reliability & Endurance: High reliability type with rated life of 10,000 hours at 105°C; endurance verified under DC bias plus rated ripple current per series specifications.
• Operating Range & Leakage: Rated for −40°C to +105°C operating temperature range with specified leakage current of 432 µA (per part data).
• Radial Lead Package: Compact φ12.5 × 25L can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assembly and manual/bulk handling; available in bulk or bag packing.
• Regulatory Compliance: RoHS compliant as specified for the UHW series.

Typical Applications

• Power supply filtering: Bulk smoothing and ripple suppression in DC power rails, leveraging 2700 µF capacitance and 2.4 A ripple rating at 120 Hz.
• High-frequency decoupling: Local energy buffering where lower impedance and 3.2 A ripple capability at 10 kHz improve transient response.
• Industrial electronics: Designs requiring long endurance at elevated temperature (10,000 hours at 105°C) and robust performance across −40°C to +105°C.

Unique Advantages

• High ripple tolerance: Designed to handle substantial low- and high-frequency ripple currents, reducing stress on upstream components.
• Compact footprint: φ12.5 × 25L radial can offers high capacitance in a small through-hole package for space-constrained boards.
• Long-term stability: 10,000-hour endurance at 105°C supports reliable operation in continuous-duty applications.
• Low impedance performance: 45 mΩ impedance helps minimize voltage drop under load and improves filtering effectiveness.
• Practical mounting and packaging: Radial lead configuration with 5 mm lead spacing and bulk/bag packing options simplify assembly and inventory handling.
• Standards compliance: RoHS compliance supports regulatory and environmental requirements for modern electronic products.
