LLS1E393MELC

The LLS1E393MELC is a snap‑in terminal aluminum electrolytic capacitor in Nichicon's LLS series, specified as an 85°C standard device. It delivers 39 mF capacitance at a 25 V rated voltage in a radial, can-style snap‑in package for general‑purpose electronic applications.

Engineered for sustained ripple duty, this capacitor is rated to withstand application of its rated ripple current for 3000 hours at 85°C and is RoHS compliant.

Key Features

• Capacitance & Voltage — 39 mF nominal capacitance at a 25 V rated voltage with ±20% tolerance.
• Snap‑in Radial Can Package — Snap‑in terminal type and radial can construction for secure PCB mounting and mechanical retention.
• High Ripple Endurance — Withstands 3000 hours of rated ripple current at 85°C; specified ripple currents: 7.56 A at 120 Hz and 8.694 A at 50 kHz.
• Operating Temperature Range — Rated for operation from −40°C to +85°C.
• Reliability Parameters — Endurance: capacitance change within ±20% and leakage current ≤ initial specified value after endurance test; tan δ limits apply per rated voltage.
• Leakage Current Specification — Leakage current I ≤ 3√(C·V) (μA) after 5 minutes' application of rated voltage at 20°C.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Dimensions — Body dimensions approximately L: 5.0 cm × D: 3.5 cm; maximum seated height 1.969 inch as specified.

Typical Applications

• General‑Purpose Electronic Equipment — Suitable where a polarized aluminum electrolytic capacitor with 39 mF/25 V is required for bulk capacitance.
• High‑Ripple Environments — Appropriate for circuits that must sustain rated ripple current for extended durations, supported by the 3000‑hour endurance at 85°C and specified ripple current values.
• Wide‑Temperature Operation — Fits applications that operate across −40°C to +85°C while maintaining specified performance limits.

Unique Advantages

• Extended Ripple Lifetime: Rated to withstand 3000 hours of rated ripple current at 85°C, helping ensure longevity in continuous‑ripple applications.
• High Ripple Current Capability: Specified ripple currents (7.56 A at 120 Hz, 8.694 A at 50 kHz) support demanding ripple workloads without immediate degradation.
• Robust Endurance Specifications: Post‑endurance limits (capacitance within ±20%, leakage ≤ initial value) provide predictable long‑term behavior under rated stress.
• Design‑Friendly Package: Snap‑in radial can simplifies mechanical mounting and retention for through‑hole assemblies.
• Compliance and Environmental Safety: RoHS compliance supports regulatory and environmental requirements for product deployment.
• Clear Electrical Limits: Defined leakage current formula and tan δ limits by rated voltage allow straightforward qualification in designs.

Why Choose LLS1E393MELC?

LLS1E393MELC combines substantial bulk capacitance (39 mF) with robust ripple endurance and clear electrical specifications, making it a practical choice for general‑purpose electronic designs that require sustained ripple handling and reliable long‑term performance up to 85°C. Its snap‑in radial can package provides mechanical stability for through‑hole assemblies while the polarized aluminum electrolytic construction delivers the expected capacitance density for bulk energy storage.

This part is well suited for engineers and procurement teams specifying standard 25 V electrolytic capacitors with documented endurance, leakage, and tan δ characteristics, and for projects that require RoHS compliance and defined performance across −40°C to +85°C.
