LKX2E221MESY30

The LKX2E221MESY30 is a 220 µF, 250 V polarized aluminum electrolytic capacitor in a snap‑in radial can package. It is designed for general‑purpose power applications, with explicit use cases in audio equipment and switching power supplies.

Engineered for elevated operating environments, this Nichicon LKX series part combines a wide operating temperature range with specified ripple handling and a 2000‑hour endurance rating at 105°C to support reliable DC filtering and energy storage.

Key Features

• Capacitance & Voltage — Rated 220 µF at 250 V with a capacitance tolerance of ±20% (120 Hz, 20°C).
• Snap‑in Radial Can Package — Snap‑in mounting for secure board retention and straightforward insertion into chassis or PCB assemblies.
• Operating Temperature & Endurance — Specified for –40°C to +105°C operation with a lifetime rating of 2000 hours at 105°C under rated bias and ripple conditions.
• Ripple Current Performance — Rated ripple current of 1.0 A at 120 Hz and 1.5 A at 50 kHz; frequency coefficient data (200–250 V) shows increasing allowable ripple up to a coefficient of 1.50 at 50 kHz and above.
• Polarized Electrolytic — Polarized design suitable for DC power filtering and energy storage applications.
• Marking & Compliance — Printed with gold lettering on a black sleeve and compliant with RoHS requirements.
• Compact Footprint — Size approximately L: 3 × D: 2 cm with a sealed snap‑in radial can package for space‑conscious designs.

Typical Applications

• Audio Equipment — Bulk and smoothing capacitor for audio power supplies; the LKX series notes material selection aimed at achieving superior acoustic sound.
• Switching Power Supplies — Energy storage and output filtering in SMPS topologies where high ripple capability and elevated temperature endurance are required.
• General‑Purpose Power Filtering — DC filtering, decoupling and bulk storage in industrial and commercial electronic equipment.

Unique Advantages

• High‑temperature endurance: Rated for 2000 hours at 105°C to maintain capacitance and leakage characteristics over extended elevated‑temperature operation.
• Frequency‑aware ripple handling: Specified ripple currents at 120 Hz and 50 kHz with documented frequency coefficients (up to 1.50 at 50 kHz) allow designers to size capacitors confidently across application frequencies.
• Secure snap‑in mounting: Radial snap‑in construction provides robust mechanical retention for board and chassis installations.
• Clear identification and compliance: Gold printed marking on a black sleeve simplifies part identification, and RoHS compliance supports regulatory requirements.
• Polarized design for DC systems: Direct suitability for DC power filtering and energy storage in common power electronics use cases.
