LLS1E273MELB

The LLS1E273MELB is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose electronic applications. It delivers high bulk capacitance (27,000 µF) in a radial, can-style snap-in package suitable for assemblies that require robust bulk energy storage and smoothing at low-voltage DC rails.

Key attributes include a 25 V rated voltage, an operating temperature range of −40 °C to +85 °C, and endurance proven for 3,000 hours at 85 °C under rated ripple conditions—making it a practical choice where long-term stability and ripple handling matter.

Key Features

• High Capacitance & Rated Voltage 27,000 µF nominal capacitance at a 25 V rating provides substantial bulk energy storage for DC bus smoothing and decoupling in general-purpose designs.
• Snap-in Terminal, Radial Can Package Snap-in mounting type and radial, can-style package simplify PCB assembly and provide secure mechanical retention in through-hole layouts.
• Temperature Range & Endurance Operating range of −40 °C to +85 °C with a specified endurance of 3,000 hours at 85 °C when subjected to rated ripple current and DC bias.
• Ripple Current Capability Rated ripple currents of 6.02 A at 120 Hz and 6.923 A at 50 kHz support continuous ripple handling under specified conditions.
• Capacitance Tolerance & Polarization ±20% capacitance tolerance at 120 Hz, 20 °C, with polarized construction for correct DC orientation.
• Compact Dimensions Package dimensions L: 4.5 cm × D: 3.0 cm (φ30 × 45 mm), providing a high capacitance-to-volume ratio for space-constrained designs.
• RoHS Compliant Constructed to meet RoHS requirements (2011/65/EU, (EU)2015/863), supporting environmental compliance goals.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling on low-voltage DC rails in general-purpose electronic equipment.
• Energy storage and hold-up — Providing stored charge for brief hold-up intervals and transient absorption in assemblies requiring large capacitance.
• Industrial and commercial electronics — High-capacitance, snap-in mounting suited to through-hole assembly practices in industrial and commercial power circuits.
