LLS2W121MELZ

The LLS2W121MELZ is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 120 µF capacitance at a 450 V rating in a compact φ22 × 35 mm can with snap‑in mounting for secure, high‑current board installation.

Engineered for sustained operation, this part provides long endurance—3000 hours at 85°C—along with defined ripple and leakage characteristics, making it appropriate for bulk energy storage, smoothing and filtering in industrial and power conversion systems.

Key Features

• Rated Electricals — 120 µF capacitance at 450 VDC with ±20% tolerance, offering high‑voltage bulk capacitance for power systems.
• High Ripple Capability — Rated ripple current of 1.07 A at 120 Hz and 1.53 A at 50 kHz to support filtering and smoothing under continuous AC ripple conditions.
• Low Leakage — Specified leakage current of 690 µA, suitable for power applications where controlled self‑discharge is required.
• Long Endurance — Designed to withstand 3000 hours at 85°C under rated conditions, with specified limits on capacitance change, tan δ and leakage after endurance testing.
• Snap‑In Radial Package — Can type, snap‑in terminals and radial mounting ease PCB insertion and secure mechanical retention in power assemblies.
• Operating Range — Rated for operation from −25°C to +85°C, matching the series’ specified temperature limits for high‑voltage variants.
• Environmental Compliance — RoHS compliant, meeting applicable restricted‑substance requirements.
• Packaging & Availability — Supplied in tray packing and available in mass production quantities for volume designs.

Typical Applications

• Power Supply Bulk Filtering — Bulk energy storage and smoothing in high‑voltage power supplies where 450 VDC rating and substantial capacitance are required.
• Industrial Power Conversion — Voltage stabilization and ripple suppression in industrial converters and inverters operating within the −25°C to +85°C range.
• Motor Drive Circuits — DC link and intermediate bus smoothing in motor drives that require high voltage and sustained ripple handling.
• Energy Storage and Filtering — Hold‑up capacitors and filter stages in general‑purpose electronic equipment that leverage long endurance and controlled leakage.

Unique Advantages

• High‑Voltage Capability: 450 V rating provides a reliable solution for high‑voltage bulk applications without the need to parallel multiple lower‑voltage parts.
• Defined Ripple Performance: Specified ripple currents at 120 Hz and 50 kHz allow designers to predict thermal and electrical behavior across common operating frequencies.
• Extended Life Under Load: 3000‑hour endurance at 85°C under rated ripple conditions supports long‑term system reliability in continuous‑use environments.
• Compact Snap‑In Form Factor: φ22 × 35 mm can with snap‑in terminals combines a small footprint with robust mechanical retention for high‑current board installations.
• Controlled Leakage: Low specified leakage current reduces self‑discharge impact in circuits that require predictable hold‑up and standby behavior.
• RoHS Compliant & Production Ready: Environmentally compliant and supplied in tray packing for streamlined production assembly.
