LLS2G471MELC

The LLS2G471MELC is an aluminum electrolytic capacitor in a snap-in terminal, radial can package designed for general-purpose applications. It combines a 470 µF nominal capacitance with a 400 V rated voltage and is specified for operation from −25 °C to +85 °C.

Designed to withstand sustained ripple stress, this part endures 3000 hours of rated ripple current at 85 °C and is RoHS compliant, making it suitable for designs that require reliable, high-voltage bulk capacitance in a snap-in format.

Key Features

• Electrical Performance — 470 µF nominal capacitance with a ±20% tolerance (measured at 120 Hz, 20 °C) and a 400 V rated voltage.
• Ripple Current Capability — Rated ripple current of 2.51 A at 120 Hz and 3.589 A at 50 kHz, enabling continuous AC ripple handling within specified limits.
• Endurance and Reliability — Specified to withstand 3000 hours with rated ripple current at 85 °C; after endurance testing, capacitance remains within ±20%, tan δ remains ≤ 200% of initial specified value, and leakage current is ≤ initial specified value.
• Low-Temperature and Loss Characteristics — Capacitance tolerance and impedance behavior documented for low-temperature performance; tangents of loss angle (tan δ) for 400 V rating are specified (max. 0.20 at 120 Hz, 20 °C).
• Mechanical & Mounting — Snap-in, radial can package with terminal dimensions suited for secure PCB mounting; overall size L: 3.5 × D: 3.5 cm and maximum seated height 1.378 inch.
• Leakage Current Specification — Leakage current defined by I ≤ 3√(C·V) (µA) after 5 minutes application of rated voltage at 20 °C, providing predictable DC leakage behavior.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Bulk capacitance for smoothing and filtering in general-purpose designs requiring 400 V rating and 470 µF capacity.
• DC bus smoothing in general-purpose systems — Provides energy storage and ripple attenuation where sustained ripple endurance at 85 °C is required.
• General-purpose bulk energy storage — Used where a polarized, high-voltage electrolytic capacitor with documented endurance and leakage specifications is needed.

Unique Advantages

• High-voltage capability: 400 V rated voltage supports designs that require elevated DC bus voltages without resorting to series capacitor arrangements.
• Proven ripple endurance: Rated to withstand 3000 hours of rated ripple current at 85 °C, helping maintain capacitance and electrical characteristics over extended operation.
• Measured ripple performance: Published ripple current values at 120 Hz and 50 kHz (2.51 A and 3.589 A, respectively) allow designers to size parts against expected AC stress.
• Snap-in packaging: Radial, snap-in can offers secure PCB mounting and straightforward assembly for panel or board-mounted bulk capacitance.
• Documented electrical limits: Leakage current formula and tan δ specification (max. 0.20 at 400 V) provide clear electrical acceptance criteria during selection and testing.
• Regulatory compliance: RoHS conformity supports deployment in environments that require RoHS-compliant components.
