UKL1E101MPD

The UKL1E101MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UKL series, designed for low leakage performance in compact applications. It delivers 100 µF capacitance at a 25 V rating in a φ8 × 11.5 mm can with 3.5 mm lead spacing.

This part is targeted at applications where low leakage and steady ripple handling matter—such as audio front-end and power decoupling circuits—while offering a 2000-hour endurance at 85°C. Note: the product status is End Of Life; availability may be limited.

Key Features

• Capacitance & Voltage — Rated at 100 µF and 25 V for energy storage and decoupling duties in low-voltage circuits.
• Low Leakage — Specified leakage current of 5 µA (typical measurement conditions at 20°C), supporting stable biasing in sensitive circuits.
• Low Loss (tan δ) — Dissipation factor (tanδ) of 0.08 at 20°C, 120 Hz, minimizing loss in AC conditions.
• Ripple Current Capability — Handles 280 mA at 120 Hz (low-frequency) and 420 mA at 10 kHz (high-frequency), useful for smoothing and decoupling across audio and power-line frequencies.
• Endurance & Temperature Range — Rated for 2000 hours at 85°C with an operating range from −40°C to +85°C.
• Compact Radial Package — Small footprint: φ8 × 11.5 mm can, 3.5 mm lead spacing (±0.5 mm) in a radial-lead format for through-hole assembly.
• Packaging & Compliance — Available in bulk or bag packing; RoHS compliant.

Typical Applications

• Audio electronics — Power-supply smoothing and coupling/decoupling in audio amplifiers and consumer audio devices where low leakage and low loss improve performance.
• Power supply filtering — Local bulk storage and ripple suppression for low-voltage rails in small-form-factor equipment.
• Embedded and portable equipment — Compact radial form provides reliable capacitance in tight PCB layouts for consumer and industrial devices.

Unique Advantages

• Low standby leakage — 5 µA leakage current helps maintain stable DC bias and reduces standby power loss in sensitive circuits.
• Measurable low dissipation — tanδ of 0.08 at 120 Hz aids in reducing AC losses and heat generation in filtering applications.
• Dual-frequency ripple handling — Specified ripple current at both 120 Hz and 10 kHz supports performance across low- and high-frequency noise environments common in audio and power electronics.
• Durability at elevated temperature — 2000-hour endurance at 85°C provides predictable lifetime behavior for designs operating in warm environments.
• Compact, through-hole convenience — φ8 × 11.5 mm can and 3.5 mm lead spacing simplify replacement and prototyping in legacy and repair applications.
• Regulatory compliance — RoHS status supports designs targeting restricted-substance requirements.
