UKL1V101KPD

The UKL1V101KPD is a radial-lead aluminum electrolytic capacitor designed for low leakage current applications. It offers 100 µF capacitance at a 35 V rating, in a compact φ10 × 12.5 mm can with 5 mm lead spacing, making it suitable for space-conscious through-hole boards in audio and related electronics.

Key electrical characteristics include low leakage (typical 7 µA), rated ripple capability (300 mA at 120 Hz, 450 mA at 10 kHz), and a rated endurance of 2000 hours at 85 °C. This product is RoHS compliant. Note: this part is End Of Life and the UKL series is scheduled for discontinuation; it is not recommended for new designs.

Key Features

• Low Leakage Current — Specified leakage current of 7 µA supports lower standby current and tighter DC bias stability where leakage is critical.
• Capacitance and Tolerance — 100 µF with ±10% tolerance (K) at 120 Hz, 20 °C for predictable filtering and decoupling performance.
• Voltage Rating — 35 V rated voltage for mid-range supply rails and common audio power rails.
• Ripple Current Handling — 300 mA at 120 Hz (low frequency) and 450 mA at 10 kHz (high frequency) for effective smoothing under dynamic load conditions.
• Endurance — 2000 hours at 85 °C with rated voltage applied, providing a defined reliability envelope for elevated operating temperatures.
• Temperature Range — Operates from –40 °C to 85 °C to cover a broad range of commercial and industrial ambient conditions.
• Compact Radial Package — φ10 × 12.5 mm can with 5 mm lead spacing and radial-lead mounting simplifies through-hole assembly and replacement in legacy boards.
• Polarized Aluminum Electrolytic — Standard polarized construction for DC smoothing, coupling and power supply filtering.
• Compliance — RoHS compliant for regulatory and environmental alignment.

Typical Applications

• Audio circuits — Low leakage and defined ripple current ratings make this capacitor suitable for power supply decoupling and smoothing in audio equipment and amplifiers.

Unique Advantages

• Reduced standby drain: Low leakage current (7 µA) helps minimize quiescent current in powered audio and consumer electronics.
• Reliable ripple performance: Rated ripple currents (300 mA @120 Hz, 450 mA @10 kHz) support effective filtering across low and high frequency components.
• Compact, serviceable form factor: φ10 × 12.5 mm radial can with 5 mm lead spacing fits space-limited through-hole PCBs and eases manual or automated insertion.
• Temperature and endurance data: Specified –40 °C to 85 °C operation and 2000 hours at 85 °C provide clear operating limits for design validation.
• Regulatory compliance: RoHS conformity simplifies environmental compliance for product assemblies.

Why Choose UKL1V101KPD?

The UKL1V101KPD provides a compact, low-leakage aluminum electrolytic solution for audio and related electronics that require well-characterized ripple handling and a defined endurance at elevated temperature. Its combination of 100 µF capacitance, 35 V rating, and radial-lead package makes it suitable for repairs, legacy boards, and applications where through-hole capacitors are preferred.

Please note the part is End Of Life and the UKL series is scheduled for discontinuation; it is therefore best suited for maintenance, replacement, or existing-production designs rather than new designs.
