UKL2A330MPD

The UKL2A330MPD is a radial-lead aluminum electrolytic capacitor engineered for low leakage current performance. It delivers 33 µF capacitance at a 100 V rating in a compact φ10 × 16 mm can with 5 mm lead spacing.

Designed for audio applications, this polarized capacitor provides a combination of high-voltage handling, defined ripple current capability across low and high frequencies, and long endurance for stabilized power and signal performance in audio circuitry.

Key Features

• Capacitance and Tolerance — 33 µF nominal capacitance with tolerance of −20% to +20% at 120 Hz, 20°C.
• High Voltage Rating — Rated at 100 V to support higher headroom in power circuits.
• Low Leakage — Specified leakage current of 6.6 µA, supporting reduced standby and bias current in sensitive circuits.
• Ripple Current Performance — Low-frequency ripple current of 180 mA (120 Hz) and high-frequency ripple capability of 360 mA (10 kHz), enabling effective smoothing across audio-relevant frequencies.
• Endurance and Temperature Range — Rated for 2000 hours at 85°C and an operating range of −40°C to +85°C for reliable performance in typical electronic environments.
• Package and Mounting — Radial lead (polarized) can package, dimensions φ10 × 16 mm with 5 mm lead spacing and 0.5 mm lead spacing tolerance, supplied bulk or in bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Audio power supply decoupling — Provides smoothing and energy storage for amplifier and preamplifier supply rails where low leakage is important to maintain bias stability.
• Audio signal conditioning — Used in coupling and decoupling roles within audio circuits, leveraging its low leakage and defined loss tangent for predictable behavior.
• Audio equipment control circuitry — Supports power filtering and transient buffering in control and peripheral circuits within audio devices.

Unique Advantages

• Low standby current: The 6.6 µA leakage rating helps minimize unwanted current draw in idle or low-power audio systems.
• High-voltage capability: 100 V rating gives designers headroom for higher-voltage supply rails or transient conditions.
• Frequency-aware ripple handling: Separate ripple ratings at 120 Hz (180 mA) and 10 kHz (360 mA) clarify performance across both power-line and audio-frequency domains.
• Compact radial form factor: φ10 × 16 mm can with 5 mm lead spacing fits confined PCB layouts while remaining serviceable for through-hole assembly.
• Durability in elevated temperature: 2000-hour endurance at 85°C supports sustained operation in warmed enclosures and long-running audio equipment.
• RoHS compliant: Conforms to current RoHS directive requirements for environmentally conscious designs.
