UHW1C682MHD

The UHW1C682MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power applications. Built on Nichicon’s UHW series architecture, it delivers high ripple-current capability and reduced high-frequency impedance in a compact φ16 × 30.5 mm package.

This radial lead, polarized capacitor is intended for designs that require a 6.8 mF capacitance at 16 V, wide operating temperature range, and long endurance at elevated temperatures.

Key Features

• Capacitance & Voltage: 6.8 mF (6800 µF) rated at 16 V with ±20% tolerance, suitable for bulk energy storage and decoupling where this capacitance and voltage rating are required.
• High ripple current performance: Low-frequency ripple current 3.4 A (120 Hz) and high-frequency ripple current 4.0 A (10 kHz), supporting demanding AC ripple conditions.
• Low impedance: Rated impedance of 33 mΩ and documented lower impedance at high frequency, improving filtering performance in switching power supplies and power rails.
• Loss characteristics: Dissipation factor (tanδ) of 0.25 measured at 20°C, 120 Hz, enabling predictable ESR/DF behavior for power design calculations.
• Reliability & endurance: Endurance rated for 10,000 hours at 105°C, providing long-term stability for sustained high-temperature operation.
• Wide temperature range: Operating from −40°C to +105°C to accommodate harsh thermal environments.
• Mechanical & mounting: Radial lead mounting with 7.5 mm lead spacing (±0.5 mm), lead diameter 0.8 mm, and compact dimensions φ16 × 30.5 mm for space-constrained layouts.
• Leakage current: Specified leakage current of 1088 µA, measurable after standard application conditions.
• Packaging & marking: Available in bulk (no terminal forming) or bag packing; marked with white lettering on a black sleeve.
• RoHS compliant: Conforms to RoHS requirements as supplied.

Typical Applications

• General-purpose power filtering: Bulk smoothing and decoupling on 16 V rails where 6.8 mF capacitance and high ripple capacity are required.
• Switching power supplies: Input/output filtering and energy buffering that benefit from the capacitor’s low impedance and high-frequency ripple current rating.
• Industrial electronics: Power rail stabilization in industrial control and instrumentation equipment requiring long endurance at elevated temperatures.

Unique Advantages

• Compact high-capacity solution: 6.8 mF in a φ16 × 30.5 mm can reduces board area compared with larger packages while preserving capacitance.
• High ripple handling: 3.4 A (120 Hz) and 4.0 A (10 kHz) ripple ratings let designers manage significant AC stress without oversizing components.
• Predictable high-frequency performance: Low impedance (33 mΩ) and documented lower high-frequency impedance support reliable filtering in switching environments.
• Long endurance at temperature: 10,000-hour life at 105°C provides design confidence for continuous high-temperature operation.
• Radial-lead convenience: Standard 7.5 mm lead spacing and 0.8 mm lead diameter simplify through-hole assembly and retrofits.
• Compliance and traceability: RoHS-compliant construction and clear sleeve marking facilitate regulatory and assembly requirements.
