LKS1J332MESC

The LKS1J332MESC is a Nichicon LKS-series snap-in aluminum electrolytic capacitor offering 3.3 mF (3300 μF) capacitance at a 63 V rating. Delivered in a radial, snap-in can (φ35 × 20 mm), this part targets general-purpose and audio equipment designs that require bulk capacitance in a compact snap-in package.

Designed for operating temperatures from −40°C to +85°C and rated for 1000 hours at 85°C, the LKS1J332MESC balances ripple handling and long-term endurance for demanding power-filtering applications.

Key Features

• Capacitance & Voltage — 3.3 mF (3300 μF) rated at 63 V with ±20% tolerance, providing bulk energy storage for power rails and smoothing applications.
• Snap-In Radial Package — Radial, can-type snap-in mounting in a φ35 × 20 mm footprint for secure chassis or PCB mounting where snap-in terminals are required.
• Ripple Current — 2.45 A ripple current (measured at 120 Hz), suitable for applications with moderate AC ripple on DC rails.
• Loss Tangent — tan δ = 0.30 (measurement at 120 Hz, 20°C) for predictable dissipation behavior in audio and power circuits.
• Leakage Current — Specified leakage current of 1360 μA (after rated voltage), enabling designers to budget standby losses accurately.
• Temperature & Reliability — Operating range −40°C to +85°C with endurance characterized to 1000 hours at 85°C.
• RoHS Compliant — Conforms to RoHS directive requirements.
• Polarized — Electrolytic polarized design for DC bulk applications.

Typical Applications

• Audio Equipment — Sized and specified for audio applications in the LKS series; suitable for power supply smoothing and bulk decoupling in audio amplifiers and related circuits.
• General-Purpose Power Filtering — Bulk capacitance for DC rail smoothing and energy storage in general-purpose electronic equipment operating up to 63 V.
• Snap-In Chassis/PCB Assemblies — Snap-in mounting provides mechanical retention for assemblies that require secure, vibration-resistant across-board installation.

Unique Advantages

• High Bulk Capacitance at 63 V: 3.3 mF nominal value provides substantial energy reserve for smoothing and transient support on higher-voltage rails.
• Compact Snap-In Footprint: φ35 × 20 mm radial can with snap-in terminals enables high-density placement while maintaining mechanical retention.
• Predictable Ripple Performance: 2.45 A ripple rating (120 Hz) and specified tan δ let designers estimate heating and performance under AC-stressed conditions.
• Endurance Characterized to 1000 h at 85°C: Provides a verifiable baseline for lifetime planning in ambient and elevated-temperature applications.
• RoHS Compliance: Facilitates deployment in environments requiring lead-free and restricted-substance conformity.
