UKL1C151MPD

The UKL1C151MPD is a radial-lead aluminum electrolytic capacitor offering 150 µF capacitance at a 16 V rating. Built for board-level power smoothing and decoupling, it delivers targeted performance for audio and low-frequency applications where compact size and low leakage are important.

Its combination of low leakage, defined ripple current capability at both low and high frequencies, and an extended operating range makes it suitable for designs that require reliable filtering and energy storage in a small radial can package.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with ±20% tolerance and a 16 V rated voltage, appropriate for a range of low-voltage power and audio circuits.
• Low Leakage Current — Specified leakage of 4.8 µA, supporting long-term bias stability and reduced standby current in DC-coupled circuits.
• Ripple Current Performance — Rated ripple current of 280 mA at 120 Hz and 420 mA at 10 kHz, enabling effective smoothing at both mains-related and higher-frequency switching/noise components.
• Endurance & Temperature — 2000 hours life at 85 °C and an operating range from −40 °C to 85 °C, providing predictable performance in elevated-temperature operating environments.
• Compact Radial Package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial-lead mounting, simplifying through-hole assembly and board placement in space-constrained designs.
• RoHS Compliant — Manufactured to meet RoHS requirements.

Typical Applications

• Audio circuits — Coupling, decoupling and power supply smoothing in audio preamplifiers, DAC/ADC front ends, and consumer audio devices where low leakage and stable capacitance matter.
• Power supply filtering — Bulk smoothing and ripple suppression at both 120 Hz and higher-frequency components (10 kHz) in low-voltage DC rails.
• Board-level through-hole designs — Small radial-can footprint and 3.5 mm lead spacing for compact assemblies requiring reliable electrolytic bulk capacitance.

Unique Advantages

• Low standby current: The specified 4.8 µA leakage supports designs where low quiescent current is required for bias stability and reduced power drain.
• Dual-frequency ripple capability: Ripple current ratings at 120 Hz and 10 kHz let designers address both mains-related ripple and higher-frequency noise with a single component.
• Compact form factor: φ8 × 11.5 mm can with tight lead spacing provides bulk capacitance without consuming excessive board area, ideal for space-limited assemblies.
• Durability at elevated temperature: 2000 hours rated life at 85 °C gives predictable end-of-life behavior for applications exposed to sustained heat.
• Through-hole ease-of-use: Radial leads and a standard can package simplify manual assembly and rework compared with surface-mount options.
• Regulatory compliance: RoHS conformity supports use in regions and products requiring restricted-substance compliance.
