UKL1J330KPD

The UKL1J330KPD is a radial-lead aluminum electrolytic capacitor designed for low leakage current applications. It delivers 33 µF capacitance at a 63 V rating in a compact can package (φ8 × 11.5 mm), optimized for audio and related electronic circuits.

With a low leakage specification, defined ripple current ratings at both low and high frequency, and a 2000-hour endurance at 85°C, this capacitor is suited to designs that demand stable DC bias behavior, compact radial mounting, and RoHS compliance.

Key Features

• Low Leakage Construction — Leakage current specified as 4.158 µA, minimizing DC bias drift and supporting stable performance in bias and coupling circuits.
• Electrical Performance — 33 µF capacitance with ±10% tolerance and a 63 V rated voltage provides consistent filtering and decoupling capacity for mid-voltage audio rails.
• Ripple Current Capability — Low frequency ripple current: 170 mA (120 Hz); high frequency ripple current: 340 mA (10 kHz), supporting both power supply smoothing and higher-frequency ripple conditions.
• Reliability & Endurance — Rated for 2000 hours at 85°C, enabling sustained operation under elevated temperature stress.
• Package & Mounting — Radial lead can (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts and manual or automated insertion.
• Environmental Compliance — RoHS compliant, meeting directive requirements for restricted substances.
• Polarized Device — Designed as a polarized electrolytic capacitor for DC applications where polarity is observed.
• Lifecycle Status — End of Life: product is listed as End Of Life; check availability and lead times before specifying.

Typical Applications

• Audio Equipment — Used for power supply smoothing, decoupling and coupling in audio amplifiers and preamplifier circuits where low leakage helps preserve bias and reduce noise.
• Power Supply Filtering — Provides bulk decoupling and ripple attenuation on mid-voltage rails up to 63 V, supporting stable DC supply voltages.
• Analog and Signal Circuits — Useful where low leakage and moderate capacitance are required to maintain DC levels and signal integrity in analog front ends.

Unique Advantages

• Measured Low Leakage: 4.158 µA leakage current specification reduces DC offset drift and lowers idle current loss in sensitive circuits.
• Dual-Frequency Ripple Ratings: Separate ripple current ratings at 120 Hz (170 mA) and 10 kHz (340 mA) quantify performance across typical audio and higher-frequency conditions.
• Compact Radial Can: φ8 × 11.5 mm package and 3.5 mm lead spacing save board area while enabling straightforward through-hole assembly.
• Proven Endurance: 2000 hours at 85°C rating provides predictable longevity under thermal stress for long-term deployments.
• RoHS Compliance: Conforms to RoHS requirements for restricted substances, simplifying regulatory compliance for electronic products.
