LNUN7102MTEF

The LNUN7102MTEF is a screw‑terminal aluminum electrolytic capacitor engineered for high‑voltage industrial power applications. It delivers 1000 µF capacitance at a DC rated voltage of 525 V and is designed for stud/bolt mounting in radial can form‑factor installations.

Built for inverter and servo drive environments, this 105°C‑rated capacitor combines high voltage handling, compact sizing relative to the LNT series, and endurance under ripple and charge‑discharge cycling to support regenerative and high‑frequency power stages.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C) and a rated DC voltage of 525 V, polarized for DC energy storage in power circuits.
• High‑Temperature Endurance — Specified for operation from −40°C to +105°C with a load life of 5000 hours when subjected to rated ripple current at 105°C.
• High Ripple & High‑Frequency Capability — Ripple current ratings of 5.4 A at 120 Hz and 7.56 A at 10 kHz support high‑power, high‑frequency inverter and regenerative loads.
• Screw Terminal / Stud Bolt Mount — Radial can with screw terminals for secure stud/bolt mounting; nominal bolt sizing for the 51 mm diameter configuration aligns with M5 fasteners.
• Charge–Discharge Endurance — Tested to withstand 50 million charge–discharge cycles (ΔV = rated voltage ±0.3, 3 Hz) while meeting capacitance, tan δ and leakage specifications.
• Leakage, Insulation & Voltage Proof — Leakage current specified as not more than 3√CV (µA) or 5 mA (whichever is smaller) after 5 minutes; insulation resistance >100 MΩ at DC 500 V and AC voltage proof between terminal and bracket.
• Compact Dimensions — Physical size L: 9.5 × D: 5.1 cm provides a compact footprint for high‑voltage applications relative to larger high‑voltage cans.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Energy storage and smoothing for inverter DC buses, supporting motor drive systems and general inverter power stages.
• AC Servomotor Regenerative Circuits — Handles high‑frequency regenerative voltages and rapid charge–discharge cycles common in servo and motion control applications.
• High‑Voltage Power Supplies — Bulk capacitance and high voltage rating for industrial power supply filter and energy buffering roles.

Unique Advantages

• High Voltage in a Reduced Footprint — Rated to DC 525 V while offering a smaller size versus comparable LNT series parts, enabling space‑efficient power module designs.
• Designed for Continuous High‑Temperature Operation — 105°C rating and a 5000‑hour load life under ripple extend service life in thermally demanding installations.
• Strong High‑Frequency Performance — Elevated ripple current capability at both low and high frequencies supports HF regenerative and inverter environments.
• Durable Cycling Capability — Proven endurance through extensive charge–discharge cycling, maintaining capacitance and leakage characteristics for cyclic applications.
• Measurable Reliability Metrics — Clear leakage, insulation resistance, and voltage proof specifications simplify reliability assessment and system validation.
• Application‑Ready Package — Screw terminals and stud‑bolt mounting in a radial can make integration and mechanical fastening straightforward for industrial assemblies.
