LAR2G221MELZ45

The LAR2G221MELZ45 is a Nichicon LAR series aluminum electrolytic capacitor in a snap‑in, radial can package. It delivers 220 µF capacitance at a 400 V rating and is designed for general‑purpose applications that require high‑voltage bulk capacitance in a compact snap‑in form factor.

This part is specified for operation from −25 °C to 105 °C and is engineered to withstand 2000 hours of rated ripple current at 105 °C, providing a balance of high‑temperature endurance and secure board mounting.

Key Features

• Rated Capacitance and Voltage: 220 µF nominal capacitance at 400 V DC, suitable for high‑voltage bulk energy storage in a single component.
• Snap‑In Radial Can Package: Snap‑in terminal type with a radial can (L: 45 mm × D: 22 mm), optimized for secure PCB mounting and higher mechanical stability.
• High‑Temperature Endurance: Specified to withstand 2000 hours of rated ripple current at 105 °C, with post‑test limits on capacitance change, tan δ, and leakage current defined in the LAR series specifications.
• Overvoltage Safety Performance: Designed to reduce short incidence when subjected to overvoltage (rated voltage × 1.5), with pressure relief venting behavior defined under limited‑current overvoltage testing.
• Ripple Current Capability: Rated ripple current of 1.1 A at 120 Hz and 1.573 A at 50 kHz (frequency dependence available in the series data), enabling effective AC filtering and decoupling at relevant frequencies.
• Operating Range and Tolerance: Operating temperature −25 °C to 105 °C with capacitance tolerance ±20% (120 Hz, 20 °C). Polarized device for correct polarity installation.
• Standards Compliance: RoHS compliant (2011/65/EU, (EU)2015/863), meeting current restricted‑substance requirements.

Typical Applications

• General‑purpose power assemblies — Provides high‑voltage bulk capacitance for circuits that require 400 V rated components in a snap‑in can.
• Industrial power modules — Suitable where extended high‑temperature endurance (2000 h at 105 °C under rated ripple) is required for sustained operation.
• High‑voltage DC filtering — Used for smoothing and energy storage in designs needing 220 µF at 400 V in a secure snap‑in package.

Unique Advantages

• High‑voltage capacity in a compact package: 220 µF at 400 V offers substantial bulk capacitance while occupying a 22 mm diameter, 45 mm length footprint.
• Long high‑temperature service life: Endurance specified for 2000 hours at 105 °C with rated ripple current ensures predictable aging and performance under thermal stress.
• Improved safety under overvoltage: Series‑defined reduction of short incidence when exposed to 1.5× rated voltage reduces risk and aids fault behavior management.
• Robust ripple handling across frequency: Specified ripple current at 120 Hz and 50 kHz, plus published frequency coefficients, help designers size parts for their operating spectra.
• Secure mounting: Snap‑in terminal construction provides reliable mechanical retention for board‑level power applications.
• Regulatory compliance: RoHS conformity supports use in regions requiring restricted‑substance adherence.
