UKL1C681MHD

The UKL1C681MHD is a radial‑lead aluminum electrolytic capacitor designed for low leakage current applications. With 680 µF capacitance at 16 V, this polarized can offers compact energy storage and filtering for audio and related electronic equipment.

Key value comes from its low leakage characteristic, defined ripple current ratings at low and high frequency, and a compact φ12.5 × 20 mm radial can with 5 mm lead spacing, making it suitable for board‑level power smoothing and decoupling in audio circuits operating between -40°C and 85°C.

Key Features

• Capacitance & Tolerance — 680 µF nominal with ±20% tolerance, providing bulk filtering and energy storage for low‑voltage power rails.
• Rated Voltage — 16 V DC rating for low‑voltage audio and consumer power applications.
• Low Leakage Performance — Specified leakage current of 21.76 µA, supporting circuits where minimal self‑discharge and low standby loss are important.
• Ripple Current Capability — Low frequency ripple current 730 mA (120 Hz) and high frequency ripple current 1.095 A (10 kHz), enabling reliable filtering under AC ripple across common audio bandwidths.
• Package & Mounting — Radial, can‑style package (φ12.5 × 20 mm) with 5 mm lead spacing (±0.5 mm), delivered in bulk or bag packing for through‑hole assembly.
• Operating Range & Endurance — Rated for -40°C to 85°C with a life/endurance of 2000 hours at 85°C, suitable for many commercial audio environments.
• Environmental Compliance — RoHS compliant construction.

Typical Applications

• Audio Electronics — Bulk filtering and power‑supply decoupling in audio amplifiers, preamps and signal processing equipment.
• Power Rail Smoothing — Energy storage and ripple reduction on low‑voltage DC rails in consumer and pro‑audio devices.
• Board‑Level Through‑Hole Designs — Straightforward radial mounting for repairable or prototype boards where can‑style capacitors are preferred.

Unique Advantages

• Low Standby Loss: The specified low leakage current (21.76 µA) minimizes self‑discharge, helping preserve stored charge in standby conditions.
• Broad Ripple Handling: Rated ripple currents at both 120 Hz (730 mA) and 10 kHz (1.095 A) accommodate filtering across low and higher frequency components common in audio power rails.
• Compact Radial Footprint: The φ12.5 × 20 mm can with 5 mm lead spacing delivers high capacitance in a small through‑hole package for space‑constrained designs.
• Designed for Commercial Temperature Ranges: Operation from -40°C to 85°C with 2000 hours endurance at 85°C supports reliable performance in typical audio equipment environments.
• RoHS Compliance: Meets RoHS requirements for lead‑free assembly and regulatory adherence in commercial products.
