LGR2D221MELZ25

The LGR2D221MELZ25 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor specified at 220 µF and 200 V. It is part of Nichicon’s LGR long‑life assurance series designed for general‑purpose applications that require high ripple handling and extended endurance at elevated temperatures.

Engineered as a radial, can‑style, snap‑in component, this polarized capacitor offers long life at up to 105°C and is RoHS compliant, making it suitable for industrial and power‑electronics assemblies where reliable smoothing and energy buffering are required.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 200 V for bulk energy storage and smoothing in high‑voltage circuits.
• Long‑life Thermal Endurance — Rated for 10,000 hours at 105°C when subjected to DC bias plus rated ripple current, with capacitance change within ±25% after the endurance test.
• Temperature Range — Operating temperature range from −40°C to +105°C, enabling operation across a broad ambient range.
• Ripple Current Handling — Rated ripple current 1.0 A (mArms) at 120 Hz; specified ripple capability increases with frequency (see frequency coefficients for 200 V series).
• High‑frequency Ripple — Measured ripple current capabilities include 1 A at 120 Hz and up to 1.5 A at 50 kHz for higher‑frequency applications.
• Low Leakage — Leakage current listed as 0.62 mA for the 220 µF, 200 V size (22 × 25 mm), supporting low‑loss energy storage.
• Mechanical & Mounting — Snap‑in radial can package (φ22 × 25 mm), designed for secure chassis or PCB snap‑in mounting.
• Capacitance Tolerance — ±20% (specified at 120 Hz, 20°C).
• RoHS Compliant — Conforms to RoHS requirements as stated in the product series documentation.

Typical Applications

• General‑purpose power electronics — Bulk smoothing and energy buffering in power supplies and industrial power modules where 200 V operation and snap‑in mounting are required.
• High‑temperature environments — Circuits that must maintain performance at elevated ambient temperatures up to 105°C and where long endurance is needed.
• Chassis or PCB snap‑in installs — Applications needing secure, quick mechanical installation using a radial snap‑in can package.

Unique Advantages

• 10,000‑hour rated life at 105°C — Demonstrated endurance for prolonged high‑temperature operation, reducing the need for frequent replacements.
• Wide operating temperature span — −40°C to +105°C range supports deployment in varied environmental conditions.
• High ripple capability across frequency — 1.0 A at 120 Hz with higher coefficients at elevated frequencies (e.g., coefficient 1.50 at 50 kHz), enabling reliable ripple dissipation across a broad frequency spectrum.
• Compact, serviceable snap‑in form factor — φ22 × 25 mm can offers a space‑efficient solution with robust mechanical retention for power assemblies.
• Predictable electrical parameters — Specified leakage current (0.62 mA) and defined tolerance (±20%) allow for precise design margining.
• Regulatory conformity — RoHS compliance supports environmental and regulatory requirements.
