UKL1J6R8MDD

The UKL1J6R8MDD is a low-leakage aluminum electrolytic capacitor in a radial lead can, offering 6.8 µF capacitance at a 63 V rating. Designed for audio applications, it provides a compact through-hole solution with a small φ5 × 11 mm case and 2.0 mm lead spacing.

Key electrical and reliability attributes include a low leakage current specification, defined ripple current performance at low and high frequencies, and a 2000-hour endurance rating at 85°C. Note: this part is listed as End Of Life and is not recommended for new designs.

Key Features

• Low Leakage Current — Specified leakage current of 0.8568 µA, minimizing DC loss for sensitive circuits.
• Electrical Ratings — 6.8 µF nominal capacitance with ±20% tolerance and 63 V rated voltage suitable for medium-voltage applications.
• Ripple Current Capability — Low-frequency ripple current 59 mA (120 Hz) and high-frequency ripple current 118 mA (10 kHz), supporting both power-supply smoothing and higher-frequency decoupling roles.
• Endurance — Rated for 2000 hours at 85°C when subjected to rated voltage, providing defined lifetime characteristics for thermal stress conditions.
• Temperature Range — Operating from −40°C to +85°C to accommodate typical commercial and audio-environment temperatures.
• Package and Mounting — Radial lead can (φ5 × 11 mm), lead spacing 2.0 mm (±0.5 mm), bulk or bag packing options; polarized for DC circuit use.
• Regulatory — RoHS compliant.

Typical Applications

• Audio circuits — Specified application for audio equipment where low leakage and compact radial packaging support coupling, decoupling, and signal-path conditioning.
• Power supply filtering — 6.8 µF capacitance and defined ripple-current ratings make this capacitor suitable for local smoothing in medium-voltage supply rails.
• Through-hole or service designs — Radial lead form factor and small footprint work well for repair, prototyping, and legacy PCB layouts that require through-hole components.

Unique Advantages

• Minimized DC leakage: Low specified leakage current (0.8568 µA) reduces unwanted DC drain and preserves circuit bias conditions.
• Compact radial can: φ5 × 11 mm case and 2.0 mm lead spacing deliver a small footprint for through-hole assemblies.
• Frequency-aware ripple handling: Separate ripple-current figures at 120 Hz and 10 kHz provide clear expectations for both low- and high-frequency applications.
• Defined endurance rating: 2000 hours at 85°C under rated voltage offers predictable lifetime behavior for thermal stress planning.
• Regulatory compliance: RoHS status ensures adherence to common material-restriction requirements.
• Simple procurement packaging: Available in bulk (no terminal forming) or bag packing to suit production or service needs.

Why Choose UKL1J6R8MDD?

The UKL1J6R8MDD combines low leakage performance, compact radial packaging, and defined ripple and endurance specifications that suit audio-focused and through-hole designs requiring reliable decoupling and filtering at 63 V. Its operating range of −40°C to +85°C and RoHS compliance make it appropriate for a variety of commercial electronic assemblies where predictable electrical behavior is required.

Because this part is listed as End Of Life and is not recommended for new designs, it is most appropriate for maintenance, repair, or existing-product continuity where the exact specification is required.
