LGY1K222MELB25

The LGY1K222MELB25 is a snap‑in terminal aluminum electrolytic capacitor designed for long‑life operation at elevated temperature. It provides 2.2 mF capacitance at an 80 V rating and is polarized for DC applications.

Engineered for industrial power applications, this part is specified for sustained ripple current at 105°C and is suited to industrial power supplies and ballast applications where dependable performance and extended life are required.

Key Features

• Capacitance & Voltage — 2.2 mF rated capacitance with an 80 V working voltage; capacitance tolerance is ±20% at 120 Hz, 20°C.
• High‑temperature, long life — Rated for operation up to 105°C with long life assurance: endurance defined as 5000 hours with DC bias plus rated ripple current at 105°C.
• Ripple current capability — Rated ripple current of 2 A at 120 Hz and 2.3 A at 50 kHz to support power supply filtering and smoothing under load.
• Operating temperature range — Specified from −40°C to +105°C for broad industrial temperature environments.
• Package & mounting — Snap‑in radial can (snap‑in terminal type) for secure board mounting; physical size approximately L: 2.5 × D: 3 cm with a maximum seated height of 2.5 cm.
• Polarized design — Polar capacitor intended for DC applications.
• RoHS compliant — Meets RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Bulk filtering and ripple handling where long life at elevated temperature is required.
• Ballasts — Designed for ballast applications that demand sustained ripple performance and thermal endurance.
• General‑purpose electronic equipment — General purpose polarized energy storage and smoothing in equipment operating within −40°C to +105°C.

Unique Advantages

• Long life at high temperature — 5000 hours endurance under rated ripple at 105°C provides a measurable lifetime metric for thermal reliability planning.
• Rated ripple current data — Published ripple current values at 120 Hz and 50 kHz allow designers to size the capacitor against expected AC stress.
• Snap‑in mounting for secure installation — Snap‑in terminal package simplifies mechanical retention and is suitable for heavier‑duty board installations.
• Wide operating temperature span — −40°C to +105°C rating supports a broad range of industrial environments without derating outside specified limits.
• Regulatory compliance — RoHS compliance supports use in designs requiring restricted‑substance conformity.
