UHW1H560MED

The UHW1H560MED is an aluminum electrolytic capacitor in Nichicon’s UHW series, offering a compact radial-can package with high ripple-current capability and high reliability. This 56 µF, 50 V polarized capacitor is designed for general-purpose electronic applications that require compact energy storage, smoothing and decoupling under elevated temperature and ripple conditions.

Key mechanical and environmental attributes include a φ6.3 × 11 mm can, 2.5 mm lead spacing, radial lead mounting, RoHS compliance, an operating range of −40°C to 105°C, and a rated lifetime of 7000 hours at 105°C.

Key Features

• Capacitance & Voltage — 56 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for predictable sizing in power and decoupling circuits.
• High Ripple Current — Rated ripple current of 280 mA at 120 Hz and 700 mA at 10 kHz, enabling effective ripple handling across low- and high-frequency domains.
• Low Loss (tan δ) — Specified tan δ of 0.10, supporting lower dissipation and stable performance under AC stress.
• Low Leakage — Specified leakage current of 28 µA, useful for minimizing standby losses in DC circuits.
• Temperature & Lifetime — Operating temperature range −40°C to 105°C with a rated lifetime of 7000 hours at 105°C for long-term reliability in higher-temperature environments.
• Compact Radial Can Package — φ6.3 mm diameter by 11 mm length, radial lead mounting with 2.5 mm lead spacing and 0.5 mm lead diameter for space-constrained PCB layouts.
• RoHS Compliant — Meets RoHS directive requirements for environmental compliance.

Typical Applications

• Power supply filtering — Compact capacitor for smoothing and decoupling on general-purpose power rails where moderate ripple currents are present.
• DC–DC converter support — Suitable for input/output filtering in small converters that require high ripple tolerance and low loss.
• General-purpose electronic equipment — Use in space-conscious circuits needing reliable polarized energy storage across −40°C to 105°C.

Unique Advantages

• High ripple capability in a small footprint — 280 mA (120 Hz) and 700 mA (10 kHz) ratings deliver effective ripple handling despite the compact φ6.3 × 11 mm can size.
• Low dissipation — Tan δ of 0.10 helps reduce heat generation under AC stress, supporting stable operation in confined assemblies.
• Designed for elevated temperatures — Rated for continuous use up to 105°C with a measured lifetime of 7000 hours at that temperature for predictable durability.
• Low standby leakage — 28 µA leakage current reduces parasitic losses in DC applications and standby modes.
• Easy PCB integration — Radial leaded can with 2.5 mm lead spacing and 0.5 mm lead diameter simplifies through-hole placement and wave or hand soldering processes.
• Regulatory compliance — RoHS-compliant construction supports environmentally conscious designs.
