LLS1J392MELZ

The LLS1J392MELZ is an aluminum electrolytic capacitor in a snap‑in radial can package designed for general‑purpose power applications. It delivers 3.9 mF capacitance at a 63 V rating with polarized construction and snap‑in terminals for secure PCB mounting.

Engineered for continuous operation up to 85°C, the device withstands 3000 hours of rated ripple current at 85°C and is RoHS compliant, making it suitable for designs that require defined electrical performance and long‑term ripple endurance.

Key Features

• Capacitance and Voltage: 3.9 mF capacitance with a 63 V rated voltage, suitable for bulk energy storage and decoupling in mid‑voltage power rails.
• Ripple Current Endurance: Specified ripple current handling of 3.09 A at 120 Hz and 3.554 A at 50 kHz, and qualified to withstand 3000 hours of rated ripple current at 85°C.
• Operating Temperature Range: −40°C to +85°C operating range to support a wide range of ambient conditions.
• Package and Mounting: Snap‑in terminal, radial can package for secure, through‑hole PCB installation. Physical size: L: 4 × D: 2.2 cm; height (seated) max: 1.575 inch.
• Tolerance and Polarization: Capacitance tolerance −20% to +20%; polarized construction for correct orientation in DC circuits.
• Compliance: RoHS compliant to 2011/65/EU and (EU)2015/863.

Typical Applications

• General Power Supply Filtering: Bulk smoothing and ripple reduction on DC power rails where 63 V and 3.9 mF are required.
• Industrial Control Equipment: Energy storage and decoupling in control electronics that operate across −40°C to +85°C and require sustained ripple endurance.
• Power Amplifier and Converter Support: Supply decoupling and reservoir capacitance in amplifier and converter stages that demand rated ripple current handling.

Unique Advantages

• Proven ripple endurance: Rated to withstand 3000 hours of applied rated ripple current at 85°C, providing predictable performance under continuous ripple stress.
• Defined ripple-current specs: Explicit ripple current values—3.09 A (120 Hz) and 3.554 A (50 kHz)—allow accurate thermal and reliability budgeting in designs.
• Robust temperature capability: −40°C to +85°C operating range supports designs exposed to wide ambient variations.
• Secure snap‑in mounting: Radial, snap‑in terminal package simplifies mechanical retention and through‑hole assembly for high‑current boards.
• Regulatory compliance: RoHS compliance aligns with environmental requirements for commercial and industrial products.
