LHX2W681MELC60

The LHX2W681MELC60 is a snap-in terminal aluminum electrolytic capacitor designed for long-life operation at elevated temperatures. This radial, can-style capacitor delivers 680 µF at a 450 V rating and is optimized for general-purpose use in equipment that requires sustained high-temperature support and reliability.

Engineered as a long-life product in the LHX series, the LHX2W681MELC60 offers a combination of high voltage, large capacitance, and extended endurance while complying with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 680 µF capacitance with a 450 V rated voltage for high-voltage energy storage and filtering in general-purpose designs.
• High-Temperature Long Life — Rated for operation from –40 °C to +125 °C with a lifetime specified as 5000 hours at 125 °C under rated conditions.
• Snap-In Radial Can Package — Snap-in terminal, radial can construction (size: 35 × 60 mm) for robust mechanical mounting and easy PCB assembly.
• Ripple Current Capability — Rated ripple current of 2.43 A (120 Hz at 125 °C); frequency coefficient data allow scaling to higher frequencies (e.g., higher ripple at kHz ranges).
• Electrical Stability — Capacitance tolerance ±20% (120 Hz, 20 °C) and low-temperature impedance stability with Z(–25 °C)/Z(+20 °C) ≤ 8 at 120 Hz.
• Leakage and Dissipation — Leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20 °C; tan δ ≤ 0.20 at 120 Hz, 20 °C.
• Regulatory Compliance & Marking — RoHS compliant; body marked with white lettering on a black sleeve for clear identification.

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance and voltage support in designs that require a 450 V, 680 µF capacitor with snap-in mounting.
• High-temperature systems — Suited to equipment that must maintain performance up to +125 °C and benefit from the LHX series long-life assurance.
• Power filtering and energy buffering — Supports AC ripple handling with specified rated ripple current and frequency coefficients for varying operating frequencies.

Unique Advantages

• Long-life performance at elevated temperature: Rated 5000 hours at 125 °C to support sustained high-temperature operation and reliability requirements.
• High-voltage, high-capacitance balance: 450 V rating combined with 680 µF capacitance addresses designs that need substantial energy storage without increasing component count.
• Snap-in mounting for robust assembly: Radial, snap-in can package simplifies board installation and mechanical retention compared with leaded axial options.
• Designed for ripple handling: 2.43 A rated ripple current at 120 Hz (125 °C) with frequency coefficients provided for scaling to higher frequencies.
• Measurable electrical stability: Specified leakage current limit (I ≤ 3√CV), tan δ ≤ 0.20, and low-temperature impedance ratio ensure predictable behavior across operating conditions.
• RoHS compliant and clearly marked: Environmentally compliant construction with printed identification for traceability.
