UKL2A101KHD

The UKL2A101KHD is a radial-lead aluminum electrolytic capacitor designed for low leakage applications. It provides 100 µF capacitance at a 100 V rating with a compact φ12.5 × 20 mm can and 5 mm lead spacing.

This part is optimized for audio applications where low leakage and reliable ripple handling are required. Note: this product is End Of Life and the UKL series is scheduled for discontinuation; the series datasheet indicates it is not recommended for new designs.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with ±10% tolerance and a 100 V rated voltage for high-voltage audio and power circuits.
• Low Leakage — Specified leakage current of 20 µA to minimize standby loss and bias drift in sensitive circuits.
• Ripple Performance — Low-frequency ripple current 370 mA (120 Hz) and high-frequency ripple current 555 mA (10 kHz) to support filtering and decoupling across a range of frequencies.
• Mechanical & Mounting — Radial lead, polarized can in a φ12.5 × 20 mm package with 5 mm lead spacing (±0.5 mm) for through‑hole assembly and hand or wave soldering workflows.
• Temperature & Endurance — Operating range −40 °C to +85 °C with endurance rated at 2000 hours at 85 °C for predictable long-term performance within the specified envelope.
• Packaging & Compliance — Available in bulk (no terminal forming) / bag packing and compliant with RoHS (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio equipment — Suited for audio circuits and power rails where low leakage and a 100 V rating contribute to stable biasing and effective filtering.

Unique Advantages

• Low standby leakage: 20 µA leakage current helps maintain bias stability and reduces parasitic losses in sensitive audio circuits.
• High-voltage capability: 100 V rating enables use in higher-voltage sections of power supplies and amplifiers without upsizing capacitance or package.
• Frequency-flexible ripple handling: Specified ripple currents at both 120 Hz and 10 kHz provide predictable thermal and performance behavior across low and high ripple frequencies.
• Compact radial package: φ12.5 × 20 mm can with 5 mm lead spacing fits common through-hole layouts while providing substantial capacitance for its size.
• Datasheet-backed endurance: 2000 hours at 85 °C offers a clear reliability specification for maintenance and legacy-support planning.
• RoHS compliance: Meets applicable RoHS directives for restricted substances.

Why Choose UKL2A101KHD?

UKL2A101KHD combines a high 100 V rating with a 100 µF capacitance and low leakage specification, making it a practical choice for audio-focused circuits and other designs that require stable bias and effective ripple suppression. Its radial-lead can and defined mechanical footprint simplify replacement and retrofit in existing boards.

Because this part is End Of Life and the UKL series is scheduled for discontinuation (not recommended for new designs), it is particularly well suited for supporting legacy products, repairs, and maintenance where direct form‑fit‑function replacement is required.
