UHW0J272MPD

The UHW0J272MPD is a radial-lead aluminum electrolytic capacitor offering 2.7 mF (2700 µF) capacitance at a 6.3 V rated voltage in a compact φ10 × 20 mm can. It is designed for general-purpose power filtering and energy storage where high ripple handling and long operating life are required.

With low impedance (60 mΩ), high ripple current capability (1.875 A at 120 Hz, 2.5 A at 10 kHz), and a 10000 h endurance at 105°C, this component targets embedded and industrial applications that need compact, reliable smoothing and decoupling in tight spaces. The part is RoHS compliant and available in bulk or bag packing for production use.

Key Features

• Electrical Performance — 2.7 mF capacitance at 6.3 V with capacitance tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Low Impedance — Rated impedance of 60 mΩ supports low-voltage, high-current filtering and helps reduce voltage ripple in power rails.
• High Ripple Current — Low-frequency ripple current: 1.875 A at 120 Hz; high-frequency ripple current: 2.5 A at 10 kHz, enabling effective AC ripple handling across common power frequencies.
• Reliability & Endurance — Life rating of 10000 hours at 105°C under rated bias, with specified limits for capacitance change, tan δ and leakage after endurance testing.
• Thermal Range — Operating temperature range from −40°C to +105°C suitable for a wide range of ambient conditions.
• Compact Radial Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm) and radial through-hole mounting for simple PCB implementation.
• Leakage and Dissipation — Specified leakage current 170.1 µA and tan δ (DF) of 0.23 measured at 20°C, 120 Hz for design budgeting of standby losses and dissipation.
• Compliance & Availability — RoHS compliant and in mass production, supplied in bulk or bag packing.

Typical Applications

• Power Rail Smoothing — Bulk decoupling and smoothing on low-voltage power rails in embedded systems, using the high capacitance and low impedance to reduce ripple.
• Switch-Mode Power Supplies — Input/output filtering where high ripple current capability (1.875 A at 120 Hz; 2.5 A at 10 kHz) and compact size are required.
• Industrial Control Electronics — Local energy storage and transient suppression in control modules operating across −40°C to +105°C.
• Consumer Power Modules — Compact radial through-hole mounting for retrofit designs and power-conditioning circuits in consumer devices.

Unique Advantages

• High ripple capacity in a small package: 2.7 mF and ripple ratings up to 2.5 A at 10 kHz deliver effective AC handling while keeping board area low (φ10 × 20 mm).
• Low impedance for tighter regulation: 60 mΩ impedance helps reduce voltage drop and ripple on low-voltage rails, improving power stability.
• Long-term reliability at elevated temperature: 10000 h endurance at 105°C supports designs that must maintain performance over extended operating periods.
• Wide operating temperature range: −40°C to +105°C suitability for varied ambient environments, from cold-starts to hot enclosures.
• Through-hole simplicity: Radial lead package with 5 mm lead spacing eases prototyping, hand-assembly, and retrofit into existing layouts.
• RoHS compliance: Meets environmental directives for lead-free assembly environments.
