LAR2E681MELC25

The LAR2E681MELC25 from Nichicon is a snap‑in, aluminum electrolytic capacitor in the LAR series, rated 680 µF at 250 V. It is designed for general purpose applications that require high capacitance in a radial, snap‑in can package with a compact φ35×25L footprint and tray packing for mass production.

Key value propositions include robust ripple handling (1.7 A at 120 Hz and 2.55 A at 50 kHz), a 2000‑hour endurance rating at 105 °C, low leakage current, and RoHS compliance for environmental conformity.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance at a rated voltage of 250 V, with capacitance tolerance of ±20% (–20% to +20%).
• Ripple Current Performance: Rated ripple current of 1.7 A at 120 Hz (low frequency) and 2.55 A at 50 kHz (high frequency), supporting designs with significant ripple demands.
• High‑Temperature Endurance: Lifetime/endurance of 2000 hours at 105 °C when D.C. bias plus rated ripple current is applied.
• Leakage Current: Specified leakage current of 1,230 µA (measured conditions as per product specifications).
• Safety under Overvoltage: LAR series construction reduces incidence of shorting when exposed to overvoltage (rated voltage × 1.5); safety performance validated per series specification.
• Operating Temperature Range: −40 °C to +105 °C, suitable for elevated ambient conditions specified for this part.
• Package & Mounting: Radial, snap‑in can (snap‑in terminal type) with dimensions φ35 × 25 L and tray packing for production handling.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — For designs that require a 680 µF, 250 V snap‑in aluminum electrolytic capacitor with specified endurance and ripple handling.
• Power Supply Modules — Where rated ripple current of 1.7 A (120 Hz) and higher frequency performance (2.55 A at 50 kHz) are needed to support DC link or bulk filtering tasks.
• Industrial Equipment — Applications that benefit from a compact φ35×25L snap‑in package and a 2000‑hour endurance rating at 105 °C for reliable operation in higher temperature environments.

Unique Advantages

• High ripple capability: Explicit ripple ratings at both low and high frequencies let designers match capacitor selection to expected ripple spectra.
• Long endurance at elevated temperature: 2000 hours at 105 °C under rated conditions provides predictable life performance for thermal‑stress applications.
• Overvoltage risk reduction: LAR series design reduces incidence of shorting under 1.5× rated voltage stress, supporting safer overvoltage behavior.
• Compact snap‑in packaging: φ35×25L radial can with snap‑in terminals enables secure PCB mounting and tray packing suited to volume assembly.
• Measured leakage performance: Specified leakage current of 1,230 µA allows designers to budget standby and leakage behavior into their system power budgets.
• RoHS compliance: Conforms to RoHS directives (2011/65/EU, (EU)2015/863) for environmentally conscious designs.
