UHW1E272MHD

The UHW1E272MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. It is a radial-lead, polarized electrolytic designed for general-purpose electronic applications that require high ripple-current capability and compact size.

Key attributes include a 2700 µF capacitance at 25 V, low impedance and high-frequency performance, and an endurance rating of 10,000 hours at 105°C—making it suited for compact power filtering and decoupling tasks in constrained assemblies.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 µF) rated at 25 V with capacitance tolerance of ±20%.
• High ripple-current capability — Rated ripple current of 2.846 A at 120 Hz and 3.795 A at 10 kHz for demanding AC stress situations.
• Low impedance — Specified impedance of 36 mΩ to support lower ESR performance in power circuits.
• Thermal and endurance performance — Operating temperature range of −40°C to +105°C and life/endurance specified at 10,000 hours at 105°C.
• Loss angle (tan δ) — tan δ = 0.15 (measured at 20°C, 120 Hz) to characterize dissipation for design validation.
• Leakage current — Specified leakage current of 675 µA.
• Package & mounting — Radial lead (can) package, size φ12.5 × 30.5 mm (L), lead spacing 5 mm with 0.5 mm tolerance; available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant.

Typical Applications

• General Purpose Electronics — Suitable where a robust 2700 µF, 25 V polarized capacitor is required for power filtering and decoupling.
• Compact Power Modules — Miniature φ12.5 × 30.5 mm can and high ripple capability help manage board-space constrained power stages.
• High-Frequency Filtering — Lower impedance and specified high-frequency ripple current (3.795 A at 10 kHz) support high-frequency smoothing tasks.

Unique Advantages

• High ripple tolerance: Explicit ripple current ratings at both 120 Hz and 10 kHz give predictable performance under AC stress.
• Compact footprint: φ12.5 × 30.5 mm radial can reduces PCB area compared with larger electrolytics while maintaining large capacitance.
• Temperature and lifetime assurance: Rated for −40°C to +105°C with 10,000 hours endurance at 105°C for long-term stability in elevated-temperature environments.
• Measured low impedance: 36 mΩ impedance supports improved power-delivery stability and reduced ripple voltage.
• Supply-ready packaging: Available in bulk or bag packing to support various assembly and procurement workflows.
• Standards compliance: RoHS compliance supports use in regulated environments requiring restricted-substance conformity.
