LNT1V223MSE

The LNT1V223MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering 22,000 µF capacitance at a 35 V rating in a φ35 × 100 mm radial can with screw terminals. It is designed for general-purpose power applications that require large bulk capacitance, secure screw-terminal connections and durable operation across a wide temperature range.

Key value propositions include high capacitance and substantial ripple-handling capability, operation from −40 °C to +105 °C, and a rated endurance of 2000 hours at 105 °C when used with rated ripple current for the 10 to 250 V range.

Key Features

• High Capacitance — 22,000 µF (22 mF) at 35 V provides significant bulk energy storage and smoothing for power rails.
• Rated Voltage — 35 V nominal working voltage suited to mid-voltage power systems and DC bus applications.
• Screw-Terminal Mounting — Radial can with screw terminals enables robust, low-impedance power connections and secure mechanical fastening.
• Wide Operating Temperature — Specified for −40 °C to +105 °C to support demanding thermal environments.
• Ripple Current Capability — Low-frequency ripple current of 5.6 A at 120 Hz and high-frequency ripple current of 6.44 A at 100 kHz to support both mains-frequency filtering and higher-frequency switching loads.
• Endurance and Reliability — Rated life of 2000 hours at 105 °C (for 10 to 250 V range) with post-test limits: capacitance change within ±20%, tan δ up to 300% of initial specified value, and leakage current within initial specified value.
• Electrical Loss Characteristics — Specified tangent of loss angle (tan δ) of 0.3 measured at 20 °C, 120 Hz.
• Leakage Current — Initial leakage current specified at 2,630 µA, measured after standard stabilization.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Power supplies and converters — Bulk smoothing and energy storage for DC rails where high capacitance and steady ripple handling are required.
• Industrial equipment — Energy buffering and decoupling in control systems and power electronics that benefit from screw-terminal secure connections.
• UPS and backup systems — Bulk capacitance for hold-up and transient support within the specified temperature and life ratings.
• Power conditioning and filtering — Low-frequency and high-frequency ripple attenuation supported by specified ripple current ratings at 120 Hz and 100 kHz.

Unique Advantages

• Large bulk capacitance in a compact can — 22,000 µF in a φ35 × 100 mm package provides substantial energy density for bulk storage without complex parallel arrays.
• Robust screw-terminal termination — Facilitates low‑impedance connections and reliable mechanical fastening for high-current or vibration-prone installations.
• Measured performance for both low and high frequencies — Specified ripple current at 120 Hz and 100 kHz enables designers to assess behavior across switching and mains frequencies.
• Designed for elevated-temperature endurance — 2000 hours at 105 °C (for the 10–250 V class) with defined post-test acceptance criteria for capacitance, tan δ and leakage current.
• Predictable electrical loss — Tan δ specified at 0.3 (20 °C, 120 Hz) provides a reference for power dissipation and thermal planning.
• Regulatory compliance — RoHS status: Compliant, simplifying environmental conformance considerations.
