UHW1A682MHD

The UHW1A682MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UHW series, designed for general-purpose electronic applications. It delivers high ripple-current capability and lower impedance at high frequencies in a compact can package, making it suitable for space-constrained power-supply and decoupling tasks where reliability and long operating life are required.

Key Features

• Capacitance & Voltage — 6.8 mF capacitance rated at 10 V for bulk energy storage and smoothing in low-voltage power rails.
• Low Impedance — Measured impedance of 39 mΩ supports stable performance at higher ripple conditions and improved high-frequency response.
• High Ripple Current — Rated ripple current of 3.239 A at 120 Hz and 3.81 A at 10 kHz to handle demanding AC ripple on DC rails.
• Compact Radial Can Package — Radial lead, can-style package with lead spacing of 7.5 mm and physical size L: 2.5 × D: 1.6 cm to save board space.
• Wide Operating Temperature — Specified for –40 °C to +105 °C operation to suit a broad range of ambient conditions.
• Long Endurance — Rated lifetime of 10,000 hours at 105 °C for extended field service life in sustained high-temperature environments.
• Polarized Design & Tolerance — Polarized capacitor with capacitance tolerance of –20% to +20% for predictable performance in polarized circuits.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements for restricted substances.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction on low-voltage DC rails where high ripple current and low impedance are needed.
• Decoupling in Compact Electronics — Local energy storage and high-frequency decoupling in space-constrained assemblies thanks to the small-can radial package.
• General-Purpose Circuitry — Reliable polarized capacitance for a variety of general-purpose electronic designs requiring long-life operation at elevated temperatures.

Unique Advantages

• Compact footprint — Physical size (L: 2.5 × D: 1.6 cm) and radial lead configuration reduce board area compared with larger cans.
• High ripple capability — Dual ripple-current ratings (120 Hz and 10 kHz) plus low impedance (39 mΩ) help manage thermal and electrical stress from AC ripple.
• Extended high-temperature life — 10,000-hour rating at 105 °C provides predictable longevity for designs exposed to sustained high temperatures.
• Broad operating range — –40 °C to +105 °C temperature capability supports deployment across varied ambient conditions.
• Regulatory compliance — RoHS compliance simplifies environmental and regulatory acceptance for commercial products.
