LAR2E681MELZ50

The LAR2E681MELZ50 is an aluminum electrolytic capacitor in a snap‑in terminal radial can designed for general-purpose power circuitry. It delivers 680 µF capacitance at a 250 V rating with a compact 22 mm diameter and 50 mm length mechanical footprint.

Designed for demanding environments, this part withstands 2,000 hours of rated ripple current exposure at 105°C and incorporates design elements to reduce short incidence under overvoltage conditions. It is RoHS compliant and tailored for applications that require durable, high-voltage bulk capacitance in a snap‑in package.

Key Features

• Electrical: 680 µF, 250 V — High-voltage capacitance for bulk energy storage with a rated voltage of 250 V and capacitance of 680 µF (±20%).
• High-temperature endurance — Rated to operate from −40°C to 105°C and specified to withstand 2,000 hours of rated ripple current at 105°C.
• Ripple current capability — Specified ripple current: 1.7 A at 120 Hz (low frequency) and 2.55 A at 50 kHz (high frequency), supporting a range of ripple conditions.
• Safety behavior under overvoltage — Designed to reduce the incidence of short when exposed to overvoltage up to 1.5× rated voltage, with pressure relief behavior specified in the datasheet.
• Snap‑in radial can package — Snap‑in terminal mounting for secure board retention and easy installation; package dimensions: D = 22 mm, L = 50 mm (height seated max 1.969 inch).
• Regulatory compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Provides bulk capacitance and ripple handling for general-purpose power electronics where a 250 V, 680 µF snap‑in capacitor is required.
• High-temperature installations — Suited to circuits that operate up to 105°C and require long-duration ripple endurance (2,000 hours at rated ripple).
• Panel and chassis-mounted power modules — Snap‑in radial can simplifies mechanical retention in assemblies that need a compact, board-mounted electrolytic capacitor.

Unique Advantages

• Proven high-temperature reliability: Endurance tested for 2,000 hours at 105°C under rated ripple current, supporting long-term operation in hot environments.
• Overvoltage safety consideration: Design reduces short incidence when exposed to 1.5× rated voltage, improving circuit-level safety during abnormal conditions.
• Frequency-aware ripple performance: Published ripple current figures at 120 Hz and 50 kHz enable informed selection for both low- and high-frequency ripple environments.
• Compact snap‑in form factor: 22 mm diameter and 50 mm length in a snap‑in radial can provide a space-efficient solution with secure board mounting.
• RoHS-compliant material set: Conforms to RoHS (2011/65/EU, (EU)2015/863), aiding regulatory alignment for assemblies.
