LLS2C272MELC

The LLS2C272MELC is a Nichicon LLS series aluminum electrolytic capacitor with a snap-in terminal design intended for general-purpose power applications. It provides 2.7 mF capacitance at a 160 V rated voltage in a radial, can-style snap-in package.

Designed for reliable ripple-current operation, this capacitor withstands 3000 hours of rated ripple current at 85°C and is RoHS compliant, making it suitable for designs that require validated endurance and environmental conformity.

Key Features

• Electrical Characteristics — 2.7 mF capacitance with ±20% tolerance and a 160 V rated voltage.
• Ripple Current Capability — Rated ripple-current handling of 5.57 A at 120 Hz and 8.355 A at 50 kHz, specified for the part.
• Temperature Range — Operating temperature range from −40°C to +85°C (applicable to rated voltages in the 16–250 V band).
• Endurance — Meets endurance requirements after 3000 hours at 85°C when DC bias plus rated ripple current is applied; capacitance change remains within ±20% and leakage current stays within initial specified limits.
• Leakage Current Specification — Leakage current defined as I ≤ 3√CV (μA) after 5 minutes' application of rated voltage at 20°C (C in μF, V in V).
• Impedance Stability at Low Temperature — For the 160 V rating, Z(−25°C)/Z(+20°C) ≤ 3 and Z(−40°C)/Z(+20°C) ≤ 12, per series specifications.
• Mechanical & Mounting — Snap-in terminal, radial can package (snap-in) for secure board or chassis mounting; physical dimensions approximately L: 4.5 × D: 3.5 cm.
• Compliance & Marking — RoHS compliant; sleeve marking printed in white on a black sleeve for clear polarity/identification.

Typical Applications

• General-purpose power systems — Bulk energy storage and ripple-current handling where a polarized, high-voltage electrolytic is required.
• Industrial power equipment — Use in systems that demand sustained ripple endurance at elevated temperatures (specified 3000 hours at 85°C).
• Chassis- or board-mounted modules — Snap-in terminal and radial can form factor for secure mounting in modular power assemblies.

Unique Advantages

• High-voltage bulk capacitance: 2.7 mF at 160 V provides significant energy storage in a compact can-style package.
• Validated ripple endurance: Specified to withstand 3000 hours of rated ripple current at 85°C, supporting designs that require long-term ripple performance.
• Frequency-specific ripple ratings: Clear ripple-current specifications at 120 Hz (5.57 A) and 50 kHz (8.355 A) simplify thermal and reliability calculations.
• Low-temperature impedance data: Published impedance ratios for −25°C and −40°C enable predictable behavior across the specified temperature range.
• RoHS compliant: Meets RoHS directive requirements for environmental conformity.
• Clear identification: White-on-black sleeve marking for polarity and part identification simplifies assembly and inspection.
