LAR2E102MELB40

The LAR2E102MELB40 is an aluminum electrolytic, snap‑in terminal capacitor rated at 250 V and 1000 µF. It is a radial, can‑style, polarized capacitor designed for general‑purpose applications that require high capacitance at elevated voltage and temperature.

Key value propositions include high‑temperature endurance (2000 hours at 105°C under rated ripple conditions), controlled safety behavior under overvoltage (reduced incidence of short when 1.5× rated voltage is applied), and RoHS compliance for regulatory compatibility.

Key Features

• Electrical Rating — 1000 µF capacitance at a rated voltage of 250 V; capacitance tolerance ±20% (at 120 Hz, 20°C).
• High‑Temperature Endurance — Specified to withstand 2000 hours of rated ripple current at 105°C; endurance criteria include capacitance change within ±20% and leakage current within initial specified value after test.
• Snap‑in Terminal / Radial Can — Snap‑in terminal type in a radial, can package for secure snap‑in mounting on appropriate boards or chassis.
• Safety Performance under Overvoltage — Designed to reduce short incidence when subjected to overvoltage of rated voltage × 1.5 (limited current test conditions), with the pressure relief vent specified to operate or remain closed without short or flame for defined passing conditions.
• Ripple Current Capability — Rated ripple current: 2.2 A at 120 Hz and 3.3 A at 50 kHz (frequency‑dependent coefficients apply as specified for the LAR series).
• Operating Range & Polarization — Polarized capacitor with category temperature range down to −40°C and up to +105°C; leakage current and tan δ specifications defined in the product data.
• Form Factor & Dimensions — φ30 × 40L (listed size: L: 4 × D: 3 cm) with a maximum seated height of 1.575 inches, facilitating compact placement where a snap‑in radial can is required.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — Suitable for general‑purpose circuits requiring a 250 V, 1000 µF snap‑in aluminum electrolytic capacitor.
• General Purpose — Applicable where sustained ripple current performance at elevated temperature (2000 hours at 105°C) is needed.
• General Purpose — A RoHS‑compliant option for general‑purpose capacitor replacement or specification in new designs.

Unique Advantages

• High‑temperature reliability: Endurance rating of 2000 hours at 105°C under rated ripple current supports longer operation in elevated ambient temperatures.
• Robust ripple handling: Published ripple current values at 120 Hz and 50 kHz provide clear selection criteria for AC and switching environments.
• Snap‑in mechanical format: Radial, can style with snap‑in terminals simplifies installation into compatible assemblies requiring secure, through‑hole mounting.
• Controlled behavior under overvoltage: Designed to reduce the incidence of shorting when exposed to 1.5× rated voltage under the specified test, with defined pressure relief behavior.
• Regulatory readiness: RoHS compliance supports use in designs that must meet current restricted‑substance requirements.
