UHW1C271MED

The UHW1C271MED is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic applications. It delivers 270 µF capacitance at a 16 V rating in a compact φ6.3 × 11 mm package with radial leads and 2.5 mm lead spacing.

Engineered for applications requiring elevated ripple handling and long-term stability, this part offers low-loss characteristics (tanδ 0.15 at 20°C, 120 Hz), defined leakage (43.2 µA), and rated endurance of 7000 hours at 105°C. Note: this part is currently listed as End Of Life.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 16 V and capacitance tolerance of ±20% (–20% to +20%).
• High ripple capability — Rated low-frequency ripple current of 350 mA at 120 Hz and high-frequency ripple current of 700 mA at 10 kHz, enabling effective smoothing in power circuits where AC ripple is present.
• Low loss — Tangent of loss angle (tanδ) specified at 0.15 (20°C, 120 Hz), suitable for applications where low dissipation factor is required.
• Leakage performance — Specified leakage current of 43.2 µA, measured after rated voltage application conditions for predictable bias behavior.
• Thermal and lifetime profile — Operational temperature range from –40°C to 105°C with a rated endurance of 7000 hours at 105°C.
• Compact radial package — φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole assemblies; available in bulk or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General power filtering: Bulk smoothing and ripple reduction in low-voltage power supplies where 270 µF at 16 V is appropriate.
• Decoupling in electronics: Local decoupling for regulators and converter outputs that require compact radial electrolytic capacitance and elevated ripple current handling.
• Embedded and industrial control: Energy storage and transient suppression in control boards operating within –40°C to 105°C and requiring extended endurance.

Unique Advantages

• High ripple tolerance: Specified ripple currents (350 mA at 120 Hz, 700 mA at 10 kHz) support robust filtering in both low- and high-frequency ripple environments.
• Compact footprint: Small φ6.3 × 11 mm can minimizes board area while delivering 270 µF capacitance for space-constrained designs.
• Long endurance at elevated temperature: 7000 hours rated life at 105°C provides predictable long-term performance in warm operating conditions.
• Predictable electrical behavior: Defined tanδ (0.15) and leakage current (43.2 µA) figures help evaluate loss and bias characteristics during design and validation.
• Through-hole simplicity: Radial-lead mounting and standard lead spacing (2.5 mm) simplify prototyping and repair in through-hole assemblies.
• RoHS compliant: Meets RoHS requirements for restricted substances.
