LGW2E681MELB30

The LGW2E681MELB30 from Nichicon is an aluminum electrolytic capacitor in a snap-in terminal (radial can) package, rated at 680 µF and 250 V. It is part of the LGW series designed for general-purpose applications where elevated ripple handling and high-temperature endurance are required.

Key value propositions include high ripple-current capability, long endurance at elevated temperature (3000 hours at 105°C), and RoHS compliance, making it suitable for designs that demand reliable bulk capacitance in a secure snap-in mounting.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 250 V and a tolerance of ±20% (measured at 120 Hz, 20°C).
• Snap-in Radial Can Package — Snap-in terminal type and radial can construction for stable board mounting and mechanical retention.
• High Ripple Current — Rated ripple current performance includes 2.55 A at 120 Hz and 3.825 A at 50 kHz; frequency coefficients for the 200–250 V range include 50 Hz: 0.81, 60 Hz: 0.85, 120 Hz: 1.00, 300 Hz: 1.17, 1 kHz: 1.32, 10 kHz: 1.45, 50 kHz or more: 1.50.
• High-Temperature Endurance — Designed to withstand 3000 hours under rated ripple current at 105°C; endurance criteria include capacitance change within ±20%, tan δ up to 200% of initial specification, and leakage current meeting initial limits after test.
• Temperature Range — Category temperature range of –40°C to +105°C for the 200–250 V rating.
• Electrical Reliability Parameters — Leakage current defined by I ≤ 3√(C·V) µA (after 5 minutes at 20°C); tangent of loss angle (tan δ) maximum 0.15 for 200–400 V at 120 Hz, 20°C.
• RoHS Compliance & Marking — Compliant with RoHS; capacitors are printed with white lettering on a black sleeve for clear identification.

Typical Applications

• General-purpose power designs — Provides bulk capacitance and ripple handling where a 680 µF, 250 V snap-in aluminum electrolytic capacitor is required.
• High-temperature environments — Suited to applications that operate up to 105°C and require long-term endurance under rated ripple conditions.
• Board-mounted assemblies — Snap-in radial can package for secure mounting in equipment assemblies demanding robust mechanical retention.

Unique Advantages

• Elevated ripple capability: Specified ripple current values (2.55 A at 120 Hz; 3.825 A at 50 kHz) and frequency coefficients support designs with significant AC stress on bulk capacitors.
• Proven high-temperature endurance: Rated to endure 3000 hours at 105°C under rated ripple, offering predictable lifetime behavior for sustained thermal stress.
• Clear electrical limits: Leakage current and tan δ specifications (including the I ≤ 3√(C·V) leakage formula and tan δ max 0.15 at 120 Hz) provide measurable acceptance criteria for production and QA.
• RoHS-compliant construction: Materials meet RoHS directives while the black sleeve with white marking ensures clear part identification.
• Secure board installation: Snap-in terminal and radial can package deliver stable mechanical retention for through-hole assembly in commercial and industrial equipment.
