LAR2E122MELB45

The LAR2E122MELB45 from Nichicon is an aluminum electrolytic capacitor in a snap‑in radial can package. It delivers 1.2 mF (1200 µF) capacitance at a 250 V rating and is specified for general‑purpose applications.

Designed for durability in elevated temperatures, the device withstands 2000 hours of rated ripple current at 105°C and includes measures to reduce short incidence under overvoltage conditions. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a 250 V rated voltage and ±20% tolerance.
• Snap‑in Radial Can Package — Snap‑in terminal mounting for secure board attachment in a φ30 × 45 mm can (size: L: 4.5 × D: 3 cm).
• High‑Temperature Endurance — Specified to withstand 2000 hours of rated ripple current at 105°C.
• Overvoltage Safety Performance — Designed to reduce short incidence when exposed to 1.5× rated voltage (safety behavior described in the series specification).
• Ripple Current Capability — Rated ripple current: 2.3 A at 120 Hz and 3.45 A at 50 kHz.
• Operating Range & Polarization — Polarized component with an operating temperature range of −40°C to +105°C.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose designs — Provides bulk capacitance and energy storage where a 250 V, 1200 µF polarized capacitor is required.
• High‑temperature environments — Suited to applications that require continuous operation and endurance at temperatures up to 105°C.
• Board‑level snap‑in mounting — Useful where a robust snap‑in radial can is preferred for secure PCB installation.

Unique Advantages

• Proven endurance at elevated temperature — 2000 hours at 105°C under rated ripple current supports reliable long‑term operation in hot environments.
• Improved overvoltage behavior — Series design reduces the incidence of shorting when subjected to 1.5× rated voltage, improving safety margins.
• Strong ripple handling — Specified ripple currents of 2.3 A (120 Hz) and 3.45 A (50 kHz) support demanding AC/rectified workloads.
• Robust mechanical mounting — Snap‑in radial can form factor provides secure board attachment for through‑hole assemblies.
• Regulatory assurance — RoHS compliance supports environmentally regulated product builds.
