LLS1J272MELA

The LLS1J272MELA is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LLS series, specified at 2.7 mF and 63 V. It is a polarized, radial can package designed for general-purpose electronic applications.

Engineered for sustained operation up to 85 °C, this part withstands 3000 hours of rated ripple-current application at 85 °C and is RoHS compliant, providing a durable capacitor option where reliable bulk capacitance and snap-in mounting are required.

Key Features

• Capacitance & Rated Voltage — 2.7 mF capacitance at a rated voltage of 63 V, with a tolerance of -20% to 20% (measured at 120 Hz, 20 °C).
• Endurance at Elevated Temperature — Specified to withstand 3000 hours of rated ripple-current application at 85 °C per the LLS series endurance specification.
• Rated Ripple Current — 2.52 A at 120 Hz and 2.898 A at 50 kHz, enabling sustained AC current handling within the rated conditions.
• Operating Temperature Range — Specified for use from –40 °C to +85 °C.
• Packaging & Mounting — Radial, can-style snap-in package for secure panel or chassis mounting; physical size L: 3 × D: 2.5 cm and maximum seated height 1.181 inch.
• Leakage Current — After 5 minutes’ application of rated voltage at 20 °C, leakage current follows I ≤ 3√CV (μA) [C: μF, V: V] as specified in the series data.
• Loss Angle (tan δ) — At 120 Hz, 20 °C, tan δ (max.) for the 63 V rating is 0.25 according to series characteristics.
• Low-Temperature Impedance Stability — For rated voltages within 16 to 100 V, impedance ratios are specified: Z(–25 °C)/Z(+20 °C) ≤ 4 and Z(–40 °C)/Z(+20 °C) ≤ 20 (measurement at 120 Hz).
• Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — Suited for general-purpose use where a polarized 2.7 mF, 63 V snap-in capacitor is required.
• Bulk Capacitance Requirements — Appropriate for designs needing bulk energy storage in a snap-in radial can format.
• Equipment Operating up to 85 °C — For applications that require components rated for operation through –40 °C to +85 °C and endurance under rated ripple current.

Unique Advantages

• Proven Endurance: 3000 hours rated ripple-current endurance at 85 °C provides long-term stability under sustained operating stress.
• High Ripple-Current Capability: Specified ripple currents of 2.52 A (120 Hz) and 2.898 A (50 kHz) support designs with continuous AC current demands.
• Snap-in Mounting Convenience: Radial snap-in package simplifies assembly and secures the component in chassis or PCB-mounted configurations.
• Measured Low-Temperature Performance: Defined impedance ratios at –25 °C and –40 °C (for 16–100 V range) give predictable behavior across cold conditions.
• Clear Electrical Limits: Leakage current defined by I ≤ 3√CV (μA) and tan δ limits provide verifiable electrical performance parameters for design validation.
• Regulatory Compliance: RoHS compliance supports environmentally regulated product builds.
