LNT1K683MSEN

The LNT1K683MSEN is an aluminum electrolytic capacitor in a screw-terminal radial can package, offering 68,000 µF capacitance at an 80 V rated voltage. Designed for general-purpose electronic systems, it provides large bulk capacitance in a rugged, serviceable screw-terminal form factor.

Key performance attributes include a wide operating temperature range of -40°C to +105°C, a rated life of 2,000 hours at 105°C, and RoHS compliance—making it suitable where sustained high-capacitance and elevated-temperature endurance are required.

Key Features

• High Capacitance — 68,000 µF (68 mF) provides substantial bulk energy storage for power systems and decoupling applications.
• 80 V Rated Voltage — Supports higher-voltage power rails within the specified rating.
• Screw Terminal Mounting — Radial can with screw terminals enables secure mechanical and electrical connections for high-current installations.
• High-Temperature Endurance — Rated life of 2,000 hours at 105°C, with defined endurance and recovery characteristics per the LNT series specifications.
• Operating Temperature Range — −40°C to +105°C to cover a wide range of environmental conditions.
• Ripple Current Capability — Specified ripple current of 17 A at 120 Hz and 19.55 A at 100 kHz to support high-current filtering requirements.
• Tolerance and Loss — Capacitance tolerance ±20% and tan δ specified at 0.4 for expected loss-angle behavior.
• RoHS Compliant — Meets RoHS directive requirements as indicated in the product data.

Typical Applications

• General-Purpose Power Systems — Bulk capacitance and smoothing for power rails where high capacitance and screw-terminal connections are required.
• High-Current Filtering — Use in circuits requiring defined ripple-current handling at 120 Hz and high-frequency conditions.
• Industrial Electronics — Suitable for equipment operating across −40°C to +105°C that needs long-life bulk energy storage.

Unique Advantages

• Large Energy Storage: 68,000 µF capacitance delivers significant bulk charge capacity to stabilize power rails and absorb transients.
• Robust Thermal Performance: 2,000-hour life at 105°C demonstrates endurance under sustained elevated temperatures.
• Secure, Serviceable Connections: Screw-terminal package simplifies installation and replacement in high-current assemblies.
• Measured Ripple Capability: Specified ripple currents at both 120 Hz and 100 kHz provide predictable thermal and electrical performance margins.
• Wide Ambient Range: −40°C to +105°C operating range supports diverse deployment environments.
• Regulatory Compliance: RoHS status supports use in applications requiring restricted-substance compliance.
