LNT2H103MSEJBB

The LNT2H103MSEJBB from Nichicon is a screw-terminal aluminum electrolytic capacitor offering 10,000 µF capacitance at a 500 V rating with a 105°C operating temperature. Built for high-voltage, high-ripple environments, this polarized radial-can capacitor targets general-purpose power applications that require large bulk capacitance, sustained ripple handling and high-temperature endurance.

Key Features

• Capacitance & Voltage — 10 mF (10,000 µF) nominal capacitance with a 500 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for high-voltage systems.
• High Temperature Endurance — Rated to operate up to 105°C with a specified load life of 2000 hours at 105°C for this voltage range, supporting sustained operation in hot environments.
• High Ripple Current Capability — Specified ripple current of 29.9 A at 120 Hz (low frequency) and 41.86 A at 100 kHz (high frequency), enabling effective smoothing in high-stress power circuits.
• Robust Mounting & Package — Screw terminal radial can package designed for secure bolted connections and durable mechanical mounting; package case noted as radial, can – screw terminals.
• Polarized Electrolytic Construction — Polar capacitor suitable for DC bias applications where high capacitance and voltage are required.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting current restricted-substance directives.
• Operating Range & Physical Size — Operating temperature range of −25°C to +105°C (for the 160 to 500 V range) and documented size dimensions L: 25 × D: 9 cm with a maximum seated height listed as 9.843 inches.

Typical Applications

• High-voltage power supplies — Bulk filtering and energy storage in 500 V power rails where large capacitance and high ripple current are required.
• Power converters and inverters — DC-link smoothing and ripple attenuation in converters that demand high-voltage bulk capacitance at elevated temperatures.
• Industrial power systems — Energy buffering and transient handling in industrial equipment and power electronics modules operating up to 105°C.
• Uninterruptible power supplies (UPS) and backup power — Bulk storage and smoothing functions in high-voltage sections that require sustained ripple performance.

Unique Advantages

• High-voltage capability: 500 V rating enables use in elevated-voltage designs without paralleling multiple lower-voltage parts.
• Large single-component capacitance: 10,000 µF provides significant bulk energy storage to reduce component count and simplify board layout.
• High ripple current rating: Specified LF and HF ripple currents (29.9 A at 120 Hz, 41.86 A at 100 kHz) help minimize temperature rise and improve reliability under heavy ripple loading.
• Designed for elevated temperatures: 105°C rating and a documented load life of 2000 hours at 105°C (for this voltage range) support demanding thermal environments.
• Secure, serviceable connections: Screw terminal radial-can package provides durable bolted attachment for high-current applications and easy field servicing.
• Regulatory compliance: RoHS conformity ensures alignment with common environmental directives.
