Key Features

• Capacitance & Tolerance — 68 µF nominal capacitance with ±10% tolerance, specified at 120 Hz and 20°C for predictable charge storage and filtering behavior.
• Voltage Rating & Polarity — Rated for 63 V DC with polarized construction appropriate for DC power and signal applications where polarity is maintained.
• Low Leakage Current — Low leakage characteristic with measured leakage of 8.568 µA, supporting long-term circuit stability and reduced standby losses.
• Ripple Current Performance — Handles 270 mA at 120 Hz (low frequency) and 540 mA at 10 kHz (high frequency), enabling effective smoothing of both mains-derived and high-frequency switching noise.
• Endurance & Temperature Range — Specified life of 2000 hours at 85°C and an operating temperature range from −40°C to +85°C for consistent operation under elevated ambient conditions.
• Package & Mounting — Radial lead (can) package, size φ10 × 16 mm with 5 mm lead spacing, suitable for through-hole mounting and manual or wave-solder assembly styles.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• Audio power supply filtering — Bulk and decoupling capacitance for audio power rails where 68 µF and 63 V rating help smooth supply ripple and support steady amplifier operation.
• Amplifier decoupling — Local rail decoupling in preamplifiers and power amplifiers, leveraging low leakage current to maintain bias stability and low noise performance.
• Signal coupling and bypass — Use in audio signal paths for coupling and high-frequency bypassing where the combination of capacitance, ripple capability, and low leakage contributes to reliable signal integrity.

Unique Advantages

• Low leakage characteristic — Measured low leakage (8.568 µA) reduces undesired current draw and helps maintain circuit biasing over time.
• Wide ripple handling span — Specified ripple currents at both 120 Hz and 10 kHz give designers confidence for mains-derived smoothing and higher-frequency switching environments.
• Robust thermal endurance — 2000 hours rated life at 85°C supports designs that operate continuously at elevated temperatures without rapid degradation.
• Through-hole radial convenience — φ10 × 16 mm radial can with 5 mm lead spacing simplifies layout and replacement in existing through-hole designs.
• RoHS compliance — Complies with RoHS requirements for materials, easing environmental compliance considerations.
