Key Features

• Capacitance & Voltage — 680 µF nominal capacitance at a rated voltage of 200 V, with a tolerance of ±20% (–20% to +20%).
• High Ripple Current Capability — Rated ripple current specified as 2.3 A at 120 Hz and 3.45 A at 50 kHz for this part number, with frequency coefficients available in the series datasheet to evaluate ripple performance across frequencies.
• High-Temperature Endurance — Designed for operation from –40 °C to +105 °C (200–250 V category) and specified to withstand 3000 hours of rated ripple current at 105 °C.
• Reliability & Endurance Specs — After 3000 hours of D.C. bias plus rated ripple current at 105 °C, capacitance change remains within ±20%, tan δ stays within 200% of initial spec, and leakage current remains at or below initial specified value.
• Leakage Current Limit — Leakage current specified by I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20 °C (C = µF, V = volts), per series specification.
• Package & Mounting — Radial can with snap-in terminals for secure board/chassis installation; polarized design suitable for correct polarity placement.
• Environmental Compliance — Compliant to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power Electronics — Suited for general-purpose designs that require a 680 µF, 200 V snap-in electrolytic capacitor with high ripple capability.
• High-Ripple Environments — Appropriate where sustained rated ripple current at elevated temperature (105 °C) is expected, supported by the 3000-hour endurance rating.
• Board or Chassis Mounting — Snap-in terminal package provides a secure mechanical mounting option for radial can implementations.

Unique Advantages

• Extended Ripple Endurance: The LGW2D681MELZ40 is specified to withstand 3000 hours of rated ripple current at 105 °C, enabling longer service life in high-stress power applications.
• Frequency-Dependent Ripple Headroom: Published frequency coefficients for the LGW series allow engineers to quantify ripple current capability across 50 Hz to 50 kHz and higher frequencies.
• High Temperature Rating: Operation down to –40 °C and up to +105 °C (200–250 V range) supports designs exposed to wide ambient ranges.
• Clear Leakage Specification: Leakage current defined by I ≤ 3√(C·V) µA after 5 minutes at 20 °C provides a verifiable baseline for leakage performance in application testing.
• RoHS Compliant: Conforms to current RoHS directives for regulatory compliance in markets requiring restricted substances adherence.
• Secure Snap-in Package: Radial snap-in can simplifies mounting and mechanical retention for chassis and board-level power assemblies.
