UHW1A272MHD

The UHW1A272MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can, offering 2700 µF (2.7 mF) capacitance at a 10 V rating. Designed for general-purpose electronic designs that require compact energy storage and robust ripple handling, the part delivers low impedance and sustained endurance across a wide temperature range.

Its core value proposition is a compact φ12.5×20 mm package with high ripple-current capability and a long rated lifetime (10 000 hours at 105 °C), making it suitable for applications where space, reliability, and thermal endurance matter.

Key Features

• Capacitance & Voltage — 2700 µF (2.7 mF) rated at 10 V for bulk smoothing and energy storage in power rails.
• High Ripple Current — Low-frequency ripple current of 1.95 A (120 Hz) and high-frequency ripple current of 2.6 A (10 kHz), supporting demanding ripple conditions.
• Low Impedance — Impedance specified at 51 mΩ to help maintain stable voltage under dynamic load.
• Long Endurance — Rated life of 10 000 hours at 105 °C under DC bias plus rated ripple current, supporting long-term reliability in thermally stressed environments.
• Wide Operating Temperature — Specified for −40 °C to +105 °C operation to accommodate a broad range of ambient conditions.
• Compact Radial Can — φ12.5×20 mm can with 5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies.
• Electrical Characteristics — Polarized device; tanδ (DF) specified at 0.2 (20 °C, 120 Hz) and leakage current listed at 270 µA.
• Compliance & Packaging — RoHS-compliant; available in bulk (no terminal forming) or bag packing. Mass-production status.

Typical Applications

• Power filtering and decoupling — Use on DC power rails to smooth voltage and absorb ripple, leveraging 2700 µF capacitance and low impedance.
• DC–DC converter output stabilization — Supports converter outputs where sustained ripple current and compact footprint are required.
• Backup energy reservoir — Provides short-term energy hold-up and decoupling for microload transients in general-purpose electronic systems.

Unique Advantages

• High ripple capacity in a small package: 1.95 A (120 Hz) and 2.6 A (10 kHz) ratings combined with a φ12.5×20 mm can enable higher-performance power circuits without a large board area penalty.
• Low impedance for stable delivery: 51 mΩ impedance helps reduce voltage droop under transient load, improving regulator and rail stability.
• Designed for extended thermal endurance: 10 000 hours at 105 °C supports long service life in thermally demanding environments.
• Through-hole radial form factor: 5 mm lead spacing and radial leads simplify assembly for through-hole boards and prototyping.
• Measured electrical characteristics: Specified tanδ (0.2) and leakage current (270 µA) provide clear engineering parameters for selection and design.
• Regulatory compliance and production readiness: RoHS-compliant and mass-production status ease procurement and integration into production designs.
