UKL1J101KPD

The UKL1J101KPD is a radial-lead aluminum electrolytic capacitor designed for low leakage current applications. It delivers 100 µF capacitance with ±10% tolerance at a rated voltage of 63 V and is supplied in a φ10×20 mm can with 5 mm lead spacing.

Key electrical characteristics include low-frequency ripple current of 330 mA (120 Hz), high-frequency ripple current of 495 mA (10 kHz), and a measured leakage current of 12.6 µA. The part is rated for an operating temperature range of −40°C to 85°C with an endurance life of 2000 hours at 85°C. Note: this part is End Of Life and is not recommended for new designs.

Key Features

• Capacitance & Tolerance: 100 µF nominal with ±10% tolerance (K), specified at 120 Hz and 20°C.
• Rated Voltage: 63 V working voltage suitable for mid-voltage power sections and filtering tasks.
• Low Leakage Current: Rated leakage current of 12.6 µA, supporting circuits where minimized standby loss and low DC leakage are important.
• Ripple Current Performance: 330 mA at 120 Hz (low frequency) and 495 mA at 10 kHz (high frequency), enabling effective smoothing across a range of ripple spectra.
• Thermal Endurance: Specified lifetime of 2000 hours at 85°C and operating range from −40°C to 85°C for stable performance in typical industrial and consumer environments.
• Package & Mounting: Radial lead, can-style package (φ10×20 mm) with 5 mm lead spacing and bulk/bag packing options for through-hole assembly.
• RoHS Compliance: Compliant with RoHS directive, suitable for regulatory-restricted applications.
• Polarized Device: Designed as a polarized aluminum electrolytic capacitor for DC filtering and decoupling use cases.

Typical Applications

• Audio circuits: Used for power supply smoothing, coupling/decoupling, and reservoir applications in audio electronics where low leakage and stable capacitance are required.

Unique Advantages

• Low leakage current: Minimizes standby and bias drain, useful in circuits sensitive to DC leakage.
• Broad ripple handling: Defined ripple current at both 120 Hz and 10 kHz supports filtering across low and high frequency components.
• Compact radial can: φ10×20 mm package balances small footprint with usable capacitance for through-hole designs.
• Temperature-rated endurance: 2000 hours at 85°C provides predictable life performance for designs operating at elevated ambient temperatures.
• RoHS compliant: Meets regulatory requirements for lead-restricted supply chains.
• Supply format flexibility: Available in bulk (no terminal forming) or bag packing to suit assembly and inventory workflows.
