LKS1H123MESC

The LKS1H123MESC is an aluminum electrolytic capacitor in a snap‑in, radial can package designed for audio equipment and general-purpose electronic designs. With a 12 mF capacitance at 50 V and a compact form factor, it is intended as a smaller-sized upgrade option where improved tonal quality and bulk energy storage are desirable.

Built for board-mounted snap‑in installation, the device offers polarized operation, a rated operating range of −40 °C to +85 °C, and RoHS compliance (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage: 12 mF rated capacitance at 50 V, suitable for bulk energy storage and smoothing in power rails.
• Tolerance & Polarization: ±20% tolerance at 120 Hz, 20 °C and polarized construction for correct DC orientation in audio and power circuits.
• Mounting & Package: Snap‑in terminal, radial can package designed for secure PCB installation and straightforward assembly.
• Operating Range: Specified for −40 °C to +85 °C operation, supporting a wide ambient temperature span for consumer and professional audio equipment.
• Endurance: Rated for 1000 hours at 85 °C under rated voltage, with defined limits for capacitance change, tan δ, and leakage after endurance testing.
• Ripple Handling: Rated ripple current of 4.2 A at 120 Hz, enabling effective ripple rejection in power supply applications.
• Regulatory Compliance: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions: Body dimensions approximately 4.0 cm length × 3.5 cm diameter, offering a smaller-sized option within the LKS series.

Typical Applications

• Audio Equipment: Bulk smoothing and power decoupling in amplifiers and audio power supplies; intended to improve tonal characteristics when replacing smaller standard capacitors.
• General‑Purpose Electronics: Energy storage and filtering in consumer and professional electronic devices where a snap‑in radial capacitor is preferred.
• Power Supply Rails: Reservoir and ripple reduction on DC power rails in systems operating within the specified voltage and temperature range.

Unique Advantages

• High Bulk Capacitance in a Smaller Can: 12 mF in a compact radial snap‑in package enables designers to increase filter capacity without a larger footprint.
• Assembly Efficiency: Snap‑in terminals provide reliable mechanical retention and simplified PCB mounting compared with leaded variants.
• Ripple Performance: 4.2 A rated ripple current at 120 Hz supports effective handling of AC ripple on power rails.
• Defined Endurance: 1000 hours at 85 °C under rated voltage gives clear expectations for lifecycle behavior in elevated-temperature applications.
• Regulatory Compliance: RoHS conformity supports use in designs requiring restricted‑substance compliance.
