UKL1C102MHD

The UKL1C102MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKL low-leakage series. It delivers 1000 µF capacitance at a 16 V rating with polarized radial can packaging and is intended for audio applications and other circuits requiring bulk capacitance with controlled leakage.

Key attributes include low leakage current, specified ripple current at both low and high frequencies, and a 2000-hour endurance rating at 85 °C. The part is RoHS-compliant and supplied in bulk or bag packing.

Key Features

• Capacitance & Tolerance — 1000 µF nominal capacitance with ±20% tolerance for bulk energy storage and decoupling needs.
• Rated Voltage — 16 V working voltage suitable for low-voltage audio circuits and general-purpose power rails.
• Low Leakage Current — Specified leakage current of 32 µA, consistent with the UKL series' low-leakage design intent.
• Ripple Current Capability — Low-frequency ripple current of 910 mA at 120 Hz and high-frequency ripple current of 1.0465 A at 10 kHz, supporting both mains-frequency smoothing and higher-frequency decoupling.
• Endurance & Temperature Range — Rated for 2000 hours at 85 °C with operating temperature range of −40 °C to +85 °C.
• Package & Mechanical — Radial can construction, size φ12.5 × 25 mm, lead spacing 5 mm (±0.5 mm), and 0.6 mm lead diameter for straightforward through-hole mounting.
• Polarized — Standard polarized aluminum electrolytic construction for correct DC circuit placement.
• Compliance & Packaging — RoHS-compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Audio — Suited for audio equipment power supply smoothing and bulk decoupling where 1000 µF and low leakage are required.
• Power Rail Decoupling — Used on low-voltage DC rails to stabilize supply and absorb load transients within its 16 V rating.
• Energy Storage — Employed where compact, through-hole bulk capacitance is needed within the φ12.5 × 25 mm footprint.

Unique Advantages

• Low Standby Drain: Leakage current specified at 32 µA helps minimize standby and quiescent currents in sensitive circuits.
• Dual-Frequency Ripple Handling: Explicit ripple ratings at 120 Hz (910 mA) and 10 kHz (1.0465 A) provide clear guidance for both low- and high-frequency smoothing needs.
• Thermal Endurance: Rated for 2000 hours at 85 °C, enabling predictable lifetime behavior in elevated-temperature environments within the specified range.
• Compact Through-Hole Form Factor: φ12.5 × 25 mm radial can with 5 mm lead spacing offers a compact, serviceable solution for through-hole designs.
• Regulatory Compliance: RoHS-compliant construction supports use in regions and products requiring restricted-substance conformity.
