UKL2A151MHD

The UKL2A151MHD is a radial-lead aluminum electrolytic capacitor providing 150 µF capacitance at a 100 V rating in a compact φ12.5 × 25 mm can. Designed for applications where low leakage and dependable ripple handling are important, this polarized capacitor is supplied in bulk or bag packing.

With a rated operating range of −40°C to 85°C and a 2000-hour endurance at 85°C, the UKL2A151MHD is targeted at audio and related electronics where stable DC performance and controlled leakage are required.

Key Features

• Electrical Capacity & Rating — 150 µF capacitance with a 100 V rated voltage and ±20% tolerance, suitable for higher-voltage circuits requiring moderate capacitance.
• Low Leakage Current — Specified leakage current of 30 µA, supporting circuits that require minimal DC bleed over time.
• Ripple Performance — Low-frequency ripple current 470 mA (120 Hz) and high-frequency ripple current 705 mA (10 kHz), providing defined ripple handling across common frequencies.
• Reliability & Endurance — Endurance rated to 2000 hours at 85°C with restoration to 20°C for post-test verification.
• Temperature Range — Operating range from −40°C to 85°C to accommodate typical electronic environments.
• Package & Mounting — Radial-lead, can-style package (φ12.5 × 25 L) with 5 mm lead spacing and 0.5 mm spacing tolerance for through-hole layouts.
• Compliance & Packaging — RoHS-compliant materials; available in Bulk (no terminal forming) or Bag packing for production or service uses.

Typical Applications

• Audio equipment — Suitable for audio circuits that require 150 µF at 100 V with low leakage, such as amplifier power supply stages and related modules.
• Power filtering in signal circuits — Used where controlled leakage and defined ripple ratings at 120 Hz and 10 kHz are required for stable DC rails.
• Through-hole electronic assemblies — Radial lead form factor and 5 mm lead spacing fit classic PCB layouts and repair/service applications.

Unique Advantages

• Low DC leakage: The 30 µA leakage specification reduces unwanted current loss and drift in DC-biased circuits.
• Defined ripple capability: Specified ripple currents at both low and high frequencies (470 mA @120 Hz, 705 mA @10 kHz) allow predictable thermal and performance planning.
• High voltage handling: 100 V rating supports designs that need greater DC headroom without upsizing capacitance form factor.
• Proven endurance: 2000 hours at 85°C provides a measurable reliability baseline for thermal endurance planning.
• Compact radial package: φ12.5 × 25 mm can and 5 mm lead spacing deliver a compact, serviceable through-hole solution for retrofits and board-level assemblies.
• RoHS-compliant: Manufactured to RoHS requirements for environmental compliance in applicable regions.
